The Rajbari Treasure of Bhutum Bagan

Chapter 1: The Night the Alien Fell into the Fish Pond

In Bhutum Bagan, a sleepy suburban corner of Kolkata where half the people claimed to be descendants of zamindars and the other half claimed the zamindars still owed them money, nothing exciting had happened since 1987, when a goat had eaten the Panchayat election poster and caused a recount.

At the centre of Bhutum Bagan stood the old Choudhury Rajbari, a three-storeyed mansion with cracked pillars, sleepy balconies, dusty chandeliers, a Durga dalan, a pond full of overconfident fish, and a family history so confusing that even the family priest had stopped explaining it after 1974.

The Rajbari belonged to nobody in particular and everybody in general. One Choudhury uncle lived in Salt Lake. One aunt lived in Toronto. One cousin had converted half a room into a gym in 2003 and never returned. The rest of the property was occupied by pigeons, bats, one retired cow, two illegal cable wires, and a ghost named Panchanan.

Panchanan was not a dangerous ghost. He had been the estate accountant in 1911. He died during an argument over whether the zamindar’s mango expenses should be entered under “fruit” or “public relations.” Since then, he floated around the Rajbari wearing a transparent dhoti and complaining about financial irregularities.

At exactly 10:43 on a humid Tuesday night, something fell from the sky.

It came down with a sound like a pressure cooker landing inside a harmonium.

“GLOP-THAP-BHISHHH!”

The object crashed into the fish pond behind the Rajbari. Water jumped like it had received an electric shock. Fish flew in all directions. One particularly large katla landed on the terrace, looked around with deep disappointment, and fainted.

The only human witness was twelve-year-old Rikto, known in the para as “Riki Telescope” because he had once used his grandfather’s broken binoculars to discover that the neighbour’s cat was secretly entering three houses for breakfast.

Riki was on the roof, doing homework under protest. He had been asked to write an essay on “The Value of Discipline.” He had written the title and then drawn a detective with a magnifying glass. That was when the sky flashed green.

Riki ran down the stairs, slipped on a sleeping dog, apologised to the dog, and reached the pond.

A round silver object, shaped like a pressure cooker designed by a mad scientist, floated among the water hyacinths. Smoke came out of it. A small hatch opened. From inside emerged a creature who looked like a nervous green coconut with two large eyes, four thin hands, three antennae, and a tiny backpack.

The creature stood on the pond steps, sneezed bubbles, and announced, “Take me to your chief fish.”

Riki blinked.

The creature blinked four times, because apparently it had extra eyelids.

“Who are you?” Riki whispered.

“I am Zorbo-9 of Planet Ulta-Palta Minor,” said the creature. “Explorer, scientist, emergency snack inspector, and temporary victim of your planet’s gravity. I came searching for intelligent life. So far I have met fish. They were rude.”

Before Riki could answer, a cold voice said, “Fish are respectable residents. Unlike certain aerial trespassers.”

Panchanan the ghost floated out of the hibiscus bush, holding an old ledger.

Zorbo-9 screamed. “Transparent human! Hardware failure!”

Panchanan screamed. “Green vegetable! British experiment!”

Riki screamed because everyone else was screaming and he did not want to feel left out.

Their combined scream woke three dogs, five crows, Inspector Malati Sen of Bhutum Bagan Police Outpost, who lived next door, and Gobindacharan Bhattacharya, the Rajbari pujari, who had been sleeping beside the temple bell because he believed thieves respected religious furniture.

Within fifteen minutes, the pond was surrounded by people.

Inspector Malati Sen arrived first, with a torch, a notebook, and the expression of someone who had seen enough local foolishness to remain calm during any crisis, including alien arrival.

Behind her came Constable Haru, carrying a lathi in one hand and a packet of muri in the other.

“Madam,” he whispered, “is this a political matter?”

“Everything becomes political if we wait long enough,” said Inspector Sen.

The pujari arrived next, his sacred thread on one shoulder, his spectacles on his forehead, and sandalwood paste applied in such hurry that he looked like he had collided with a bowl of payesh.

“Who has disturbed the pond of Mother Lakshmi?” he cried.

Zorbo-9 raised one hand. “I apologise to Lakshmi authority. My craft suffered from mishti-doi vapour interference.”

“Mishti doi?” said Riki.

“Yes. Your city emits dangerous levels of sweet fermented dairy radiation. My navigation system thought it was premium rocket fuel.”

At this point, a tall, thin man in a crumpled linen suit entered through the gate, holding an umbrella though there was no rain.

This was Detective Haripada Halder, known professionally as H. Halder, known socially as “Half-pant Holmes” because in childhood he had solved the mystery of the missing school tiffin while wearing half-pants. He now claimed to be a consulting detective. His office was above a tyre shop near Gariahat, and his business card said:

H. HALDER

Private Detective

Missing Persons, Missing Cats, Missing Jewellery, Missing Logic

He had come to Bhutum Bagan because Gobindacharan Bhattacharya had reported that temple coconuts were disappearing every Thursday. Halder had suspected either a thief, a monkey, or a committee member.

He looked at the alien. He looked at the ghost. He looked at Riki.

“Excellent,” he said. “The coconut case has improved.”

Inspector Sen gave him a dry look. “Halder-babu, do not touch evidence.”

“I never touch evidence,” said Halder. “I only mentally disturb it.”

From the shadows near the old granary, another pair of eyes watched everything. These eyes belonged to Nolen Das, a small-time thief, part-time pickpocket, full-time philosopher, and specialist in stealing useless things by mistake. He had once stolen a schoolbag thinking it contained gold, and found three grammar books and a tiffin box of bitter gourd.

Nolen had come that night to steal brass lamps from the Rajbari temple. Instead, he had seen an alien, a ghost, a detective, police, and a pujari arguing about pond pollution.

“Baba re,” whispered Nolen. “Tonight’s crime market is overcrowded.”

He quietly moved backward and stepped on the tail of the retired cow.

The cow mooed like a broken trumpet.

Everyone turned.

Nolen froze.

“Who is there?” shouted Inspector Sen.

Nolen tried to run but slipped on moss and fell face-first into a bucket.

Zorbo-9 pointed. “Chief fish?”

“No,” said Riki. “Local thief.”

“I object,” said Nolen from inside the bucket. “I am an independent property redistribution consultant.”

Just then, Panchanan the ghost suddenly stiffened. His transparent moustache trembled.

“Property,” he whispered. “Redistribution. Treasure. Ledger. Lock number seven.”

Detective Halder’s eyes sharpened.

“What treasure?”

Panchanan looked toward the broken western wing of the Rajbari. The moonlight touched the cracked arches. For one second, the old mansion seemed awake.

“The Choudhury treasure,” said the ghost. “Gold mohurs, jewels, emerald waist-belt, ruby crown, diamond anklets, and one silver paan box nobody liked but everyone fought over. Hidden before the estate collapsed. Lost for almost a hundred years.”

The pujari gasped. “The legend is true?”

Inspector Sen closed her notebook. “If there is treasure, there will be crime.”

From beyond the boundary wall came the faint sound of a truck engine.

At the far end of Bhutum Bagan, a gang of smugglers had already heard the news. Their leader, Balaram “Boka Bali” Sardar, was not actually foolish, though his nickname meant otherwise. He had smuggled antique idols, fake antiques, genuine fake antiques, and once, by mistake, twelve sacks of organic cauliflower.

Tonight he sat in a truck marked Dhulomati Heritage Export: Cultural Logistics Since Yesterday.

Beside him were his men: Paltan, who could break locks but not passwords; Chapal, who could climb walls but feared lizards; and Titli, who handled accounts and had the cold eyes of a tax officer.

Boka Bali smiled.

“Long-lost treasure,” he said. “Police there. Detective there. Ghost there. Alien also there. Perfect. While fools argue, professionals dig.”

Back at the pond, Zorbo-9’s spaceship made a sad burping noise and sank three inches.

“My craft needs repair,” said Zorbo. “I require gold, jewels, and fermented sweets.”

Detective Halder opened his umbrella with dramatic force.

“Then we have a case,” he declared. “An alien needs fuel, a ghost has memory trouble, a boy has courage, a thief has fallen in a bucket, police have suspicion, a priest has panic, and a Rajbari hides treasure.”

Riki grinned.

Panchanan adjusted his transparent ledger.

Inspector Sen sighed.

Nolen removed the bucket from his head.

And somewhere inside the old Rajbari, behind a wall that had not opened in ninety-six years, something clicked.

Chapter 2: The Zamindar’s Curse and the Scientist’s Umbrella

The next morning Bhutum Bagan woke up with three rumours.

First, that a ghost had joined the police.

Second, that a green foreigner had come to buy the Rajbari.

Third, that the Panchayat Pradhan was going to turn the pond into an international airport.

All three rumours reached Panchayat Pradhan Pankaj Mondal before breakfast. Pankaj Mondal was a round man with a round face, round glasses, and round opinions that changed direction depending on who was listening. He reached the Rajbari wearing a spotless kurta and a smile usually seen on people opening schemes.

“What is happening here?” he demanded. “As elected representative, I must be informed before any alien landing.”

Inspector Sen replied, “The alien did not apply through Panchayat.”

“That is exactly the problem,” said Pankaj. “No decentralisation.”

Detective Halder had converted the old thakurdalan into a temporary investigation room. On one side sat Riki with a notebook. On another side sat Zorbo-9, drying his antennae with a gamchha. Panchanan floated upside down near the ceiling because he said it helped memory. Nolen Das sat under supervision, eating muri and looking offended.

Gobindacharan the pujari stood near the temple door. He had tied three extra protective threads around his wrist and one around his spectacles.

“I always knew the treasure existed,” he announced. “In our family, we have served this temple for seven generations. My grandfather told my father, my father told me, and I forgot to tell myself.”

Halder tapped the table. “Facts only.”

The pujari coughed. “Fact: Raja Umaprasad Choudhury hid the treasure around 1930 when estate cases, tax disputes, family quarrels, and British officials made life unpleasant.”

Panchanan nodded. “Correct. There was also a lawsuit over fourteen mango trees.”

“Where did he hide it?” asked Riki.

Panchanan frowned. “That is the problem. I was the accountant. I wrote the coded entry. Then I died during the mango argument. Since then, I remember everything except the useful part.”

“Convenient,” said Inspector Sen.

Panchanan looked hurt. “Madam, dying is already inconvenient.”

At this moment, a cycle bell rang outside like a mosquito with ambition. A man entered wearing a laboratory coat, rubber sandals, and a helmet made from an old pressure cooker.

“Move aside!” he cried. “Science has arrived late but with confidence!”

This was Professor Protul Chandra Pixel, retired scientist, amateur inventor, and full-time disaster. He claimed to have worked in cosmic acoustics, quantum archaeology, and machine-assisted gossip detection. His most famous invention was a solar-powered mosquito repellent that attracted mosquitoes from other districts.

He rushed to Zorbo-9 and bowed.

“My extraterrestrial colleague!”

Zorbo examined him. “Are you Earth scientist?”

“Yes.”

“Then why is your head inside cooking vessel?”

“For protection from unknown rays.”

“There are no rays.”

“Then it is working.”

Professor Pixel set up three instruments: a copper coil, a transistor radio, and an umbrella connected to a battery.

“This device,” he declared, “will detect hidden metallic objects using advanced principles of magnetism, vibration, and hope.”

He switched it on.

The umbrella opened violently and hit Pankaj Pradhan on the nose.

“Excellent,” said Halder. “It has detected politics.”

Inspector Sen rubbed her forehead.

Riki, meanwhile, studied an old framed painting in the thakurdalan. It showed Raja Umaprasad standing beside the Durga idol, one hand on a sword, the other on a book. Beneath the painting was a line in faded Bengali:

“Where the lion drinks, where the moon wears shoes, where seven accounts sleep, there rests the debt of gold.”

Riki read it aloud.

Everyone became silent.

Then Nolen said, “Lion drinks? Impossible. Lion takes only mineral water.”

Panchanan trembled. “That line. I wrote it in the ledger.”

Halder leaned forward. “What does it mean?”

The ghost squeezed his eyes. “The lion may be the Durga lion. The moon may be the old moon-shaped window. Seven accounts may refer to seven ledgers. Or seven rooms. Or seven unpaid salaries. Umaprasad-babu was poetic only when avoiding tax.”

Professor Pixel’s umbrella beeped.

“Metal detected!” he shouted.

Everyone ran after him into the courtyard. The umbrella dragged him to a corner near the well. Constable Haru dug with a spade. After ten minutes he found a rusted tiffin carrier.

Gobindacharan gasped. “Treasure?”

Inspector Sen opened it. Inside was a petrified luchi from approximately 1952.

Professor Pixel looked proud. “Ancient carbohydrate.”

During the excitement, Nolen slowly slipped toward the gate. He had almost escaped when Zorbo’s antenna stretched like a fishing rod and lifted him by the collar.

“Independent redistribution consultant attempting redistribution of himself,” said Zorbo.

Nolen sighed. “Your technology lacks respect for small business.”

But Riki noticed something. When Zorbo’s antenna extended, the old temple bell began to vibrate. Not loudly. Just a faint hum. The Durga lion statue beside the idol also shifted a little.

“Wait,” said Riki. “Zorbo, do that again.”

Zorbo stretched his antenna.

The bell hummed. The lion’s stone mouth opened slightly.

The pujari screamed, “Ma! The lion is yawning!”

Halder knelt near the statue. Inside the lion’s mouth was a small brass tube.

Inspector Sen removed it carefully. Inside was a rolled strip of old cloth.

On it was written:

“The first key is not metal.Ask the one who stole but did not sell.Ask the one who died but did not leave.Ask the child who sees what elders step over.”

Everyone turned to Nolen.

Nolen looked alarmed. “Why me? I only steal things that are already neglected.”

Halder smiled. “Exactly. Did you ever steal anything from this Rajbari but fail to sell it?”

Nolen scratched his head. “Many things. One cracked mirror. One brass handle. One broken hookah. One framed certificate of Sanskrit excellence. Nobody bought. Terrible resale market.”

“Where are they?”

“In my aunt’s cowshed.”

Inspector Sen ordered Constable Haru to fetch them.

Pankaj Pradhan clapped. “This is becoming a heritage recovery mission. We can create employment. Ticket counter here, selfie point there, alien interaction platform near pond.”

Zorbo whispered to Riki, “Is this chief fish?”

“No,” said Riki. “Worse. Local governance.”

By afternoon, Haru returned carrying a sack of stolen junk. The cracked mirror was ordinary. The hookah was ordinary. The Sanskrit certificate had been eaten by termites with educational ambition.

But the brass handle was strange. It was shaped like a fish with three eyes.

Panchanan floated down. “Three-eyed fish. Umaprasad-babu’s private symbol.”

Riki turned the handle over. There were tiny letters scratched on the back:

“Attach where the moon wears shoes.”

“The moon wears shoes,” repeated Halder.

At that moment Dr. Hiranmoy Halder arrived, though nobody had called him. He was the local doctor, unrelated to the detective but strongly offended that people assumed all Halders were cousins. He carried a leather bag, a stethoscope, and a permanent expression of medical suspicion.

“I heard there is an alien, a ghost, and a treasure fever,” said Dr. Halder. “Naturally, I came.”

“Doctor, this is not a disease,” said Inspector Sen.

“Everything is a disease until proven political.”

He examined Zorbo with the stethoscope.

“No heartbeat,” he announced.

“I have four pulse bubbles,” said Zorbo.

“Serious condition.”

He examined Panchanan.

“No pulse. No temperature. No body. Chronic case.”

Panchanan said, “I am dead.”

“That explains some symptoms.”

While everyone argued, Riki looked toward the western wing. High above the broken staircase was a round window shaped like a crescent moon. Beneath it, two stone brackets stuck out like feet.

“The moon wears shoes,” he whispered.

They climbed to the western wing. Dust lay thick. Bats complained. Professor Pixel’s umbrella detected one nail, two coins, and Dr. Halder’s stethoscope.

At the crescent window, Riki fixed the three-eyed fish handle between the two stone brackets. It fit perfectly.

A panel in the wall opened.

Inside was a small chamber containing seven ledgers.

Panchanan gave a soft cry.

“My accounts!”

Halder opened the first ledger. Most entries were boring: rice, oil, court fees, elephant medicine. But in the seventh ledger, one page was sealed with red wax.

Inspector Sen broke the seal.

Inside was a map of the Rajbari drawn in black ink. At the bottom was a warning:

“The treasure belongs not to greed but to guardianship.Those who steal shall sneeze truth.Those who lie shall hear bells.Those who dig blindly shall fall.”

Far outside, near the bamboo grove, Boka Bali and his smugglers listened through a hidden microphone fixed inside a clay pot.

Paltan whispered, “Boss, we should steal the map.”

Boka Bali smiled. “No. Let them solve the puzzle. Then we take the treasure.”

Titli opened her notebook. “Efficient theft through outsourced research.”

Chapal sneezed.

Boka Bali frowned. “Why sneeze?”

Chapal panicked. “I was thinking of stealing the alien also.”

From the Rajbari temple, the bell rang once by itself.

Chapter 3: The Thief, the Pujari, and the Smugglers’ Documentary

By evening, Bhutum Bagan had become famous.

Children gathered at the Rajbari gate chanting, “Alien! Alien! One selfie!”

A sweet shop sent complimentary sandesh because the owner wanted “interplanetary customer review.”

A local YouTube channel arrived with the headline: GHOST-ALIEN TREASURE LIVE: POLICE SILENT, PUBLIC VIOLENTLY CURIOUS.

Inspector Sen locked the main gate and declared the Rajbari a restricted area. Naturally, this made more people climb the wall.

Detective Halder spread the old map on a table.

The map showed the Rajbari, pond, temple, granary, cowshed, old music room, and a tunnel leading toward the river. Three symbols were marked: a lion, a moon, and a conch.

“We found the lion and moon,” said Riki. “Now conch.”

Gobindacharan puffed up. “The temple has five conches. One for morning worship, one for evening worship, one cracked, one decorative, and one missing since 1962 due to suspected cousin involvement.”

Panchanan raised a ghostly finger. “Not temple conch. Estate conch. The zamindar used a large ceremonial conch during Durga Puja. It was kept in the music room.”

The music room was on the first floor. Once, famous singers had performed there. Now it contained broken chairs, pigeon feathers, a harmonium with emotional damage, and portraits of ancestors who looked disappointed with modern times.

Zorbo scanned the room with his wrist device.

“Organic dust: 71 percent. Pigeon authority: high. Musical sadness: extreme.”

Nolen sneezed.

Inspector Sen turned. “Why are you sneezing?”

Nolen’s eyes widened. “I was thinking of stealing that small portrait frame.”

The temple bell rang faintly.

Everyone stared.

“The curse works!” cried Gobindacharan. “Those who steal shall sneeze truth!”

Nolen became pale. “This is a professional hazard.”

They searched the room. Behind a broken tanpura, Riki found the ceremonial conch. It was large, heavy, and painted with faded gold lines. But its mouth was sealed with wax.

Dr. Halder tapped it. “Could contain germs.”

Professor Pixel tapped it. “Could contain cosmic sound.”

Nolen tapped it. “Could contain resale value.”

The bell rang.

“Sorry,” said Nolen.

Inside the conch they found another clue, written on thin copper foil:

“To open the sleep of gold, assemble four witnesses:The hand of law,The hand of faith,The hand of science,The hand of mischief.”

Inspector Sen said, “Law.”

Gobindacharan said, “Faith.”

Professor Pixel said, “Science.”

Everyone looked at Nolen.

Nolen bowed modestly. “At last, social recognition.”

The copper foil also mentioned a place: The Hall of Twelve Echoes.

Panchanan explained. “Below the Rajbari there is an old underground hall. It connected the temple, granary, and riverside warehouse. During storms, goods were stored there. During lawsuits, documents were hidden there. During family quarrels, relatives were hidden there.”

“Where is the entrance?” asked Halder.

“Behind the Durga dalan,” said Panchanan. “But it was sealed after the incident of 1929.”

“What incident?”

Panchanan looked embarrassed. “A goat entered and became zamindar for three hours.”

Before the team could move, Pankaj Pradhan returned with garlands.

“I have spoken to district officials,” he announced. “This treasure must be used for development. We can create Bhutum Bagan International Heritage Eco-Spiritual Alien Tourism Circuit.”

Inspector Sen said, “First we must recover it legally.”

“Of course,” said Pankaj. “Legal recovery, then committee, then subcommittee, then advisory group, then foundation stone.”

Zorbo whispered, “Your planet moves slowly.”

“Only files,” said Riki. “People move fast when there is free food.”

Just then, three men and one woman entered through the gate carrying cameras, microphones, and fake identity cards.

“Documentary team,” said the woman briskly. “From Global Heritage Vision Media Culture Channel.”

She was Titli, the smugglers’ accountant.

Behind her were Boka Bali wearing a director’s scarf, Paltan carrying a camera without lens, and Chapal holding a boom mic that was actually a metal detector.

Inspector Sen blocked them. “Who gave permission?”

Pankaj Pradhan raised his hand halfway, then lowered it after seeing Inspector Sen’s face.

Boka Bali smiled smoothly. “Madam, we are here to preserve culture.”

Panchanan floated through him accidentally.

Boka Bali shivered. “Culture is cold.”

Zorbo sniffed him. “You smell of river mud, engine oil, and dishonest ambition.”

Boka Bali laughed. “Alien humour! Wonderful footage.”

Detective Halder noticed Chapal’s boom mic was beeping near the temple wall.

“Interesting microphone,” he said.

Chapal panicked. “It records deep emotions.”

Nolen suddenly sneezed.

Inspector Sen looked at him.

Nolen pointed at the documentary team. “They are smugglers! Sorry. I thought of stealing their wallet and saw fake ID.”

The temple bell rang violently.

Boka Bali’s smile disappeared.

“Run!” shouted Titli.

The smugglers scattered.

What followed became famous in Bhutum Bagan history as the Great Heritage Chase.

Paltan ran into the cowshed and was chased out by the retired cow, who had developed strong anti-crime views.

Chapal climbed the mango tree, saw a lizard, and surrendered to a squirrel.

Titli tried to escape through the kitchen but slipped on spilled mustard oil and slid across the courtyard like a professional athlete in a new sport.

Boka Bali, however, escaped through a side passage near the granary.

Inspector Sen sent Constable Haru after him. Haru ran bravely for six steps, then returned.

“Madam,” he said, “passage is dark.”

“Take a torch.”

“Torch is also scared.”

By the time they reached the granary, Boka Bali had vanished.

But he had left behind a torn paper. Professor Pixel picked it up.

It was a copy of part of the old map.

Halder’s face became serious. “They know about the underground hall.”

Panchanan shivered. “Then they may find the river entrance.”

Riki looked at the map again. The Hall of Twelve Echoes lay beneath the Durga dalan. But another tunnel connected it to an abandoned warehouse near the old canal.

“If the smugglers enter from outside,” he said, “they can reach the treasure before us.”

Inspector Sen loaded her revolver.

“No one enters without police.”

Gobindacharan clutched his bell. “No one enters without mantra.”

Professor Pixel adjusted his pressure-cooker helmet. “No one enters without science.”

Nolen raised his hand. “No one enters without someone who knows how locks actually behave.”

Dr. Halder sighed. “No one enters without medical supervision. Ghost, alien, detective, thief, priest—this is already a hospital case.”

Zorbo opened his backpack and pulled out a glowing purple cube.

“This can detect underground cavities,” he said. “But it needs emotional calibration.”

“What does that mean?” asked Riki.

“Someone must tell it a sincere secret.”

Everyone looked at Nolen.

Nolen folded his arms. “Why always me?”

The cube glowed.

Nolen sighed. “Fine. I once stole my own bicycle because I forgot it was mine.”

The cube hummed happily and projected a 3D image of the underground tunnels.

Professor Pixel stared, deeply offended. “This alien toy is better than my umbrella.”

“Do not worry,” said Zorbo kindly. “Your umbrella has excellent political detection.”

The projection showed three routes to the Hall of Twelve Echoes. One from the temple, one from the granary, and one from the canal warehouse.

A red dot moved in the canal tunnel.

Boka Bali had already entered.

Inspector Sen snapped, “Move.”

The team gathered at the Durga dalan. Gobindacharan pushed aside a stone lotus behind the idol platform. A hidden staircase opened with a grinding sound.

Cold air rose from below.

Panchanan floated down first, then floated back up immediately.

“Problem,” he said.

“What problem?” asked Halder.

“Rats.”

Riki stared. “You are a ghost.”

“Yes,” said Panchanan. “Not a foolish ghost.”

From the darkness below came a sneeze.

Then a voice echoed: “I am not stealing. I am only pre-recovering!”

The bell rang.

The treasure hunt had officially entered the underground.

Chapter 4: The Hall of Twelve Echoes

The staircase beneath the Durga dalan was narrow, damp, and smelled of wet earth, old incense, and secrets that had not been cleaned for generations.

Inspector Sen went first with her torch. Behind her came Detective Halder, Riki, Zorbo-9, Gobindacharan, Professor Pixel, Dr. Halder, Nolen, Constable Haru, and finally Panchanan, who floated while lifting his feet though he had no need to.

“Ghosts do not step on rats,” he explained. “It is a matter of dignity.”

The passage walls were built of old brick. Moss covered the corners. Here and there, tiny terracotta tiles showed fish, lotus, owls, and strange symbols.

Zorbo touched one tile. “This architecture is emotionally unstable.”

“That is Bengal,” said Halder.

After fifty steps, they reached a round chamber. Twelve arched openings circled the wall. Each opening led into darkness. In the centre stood a stone platform with four hand-shaped depressions.

“The Hall of Twelve Echoes,” whispered Panchanan.

Gobindacharan chanted a mantra with such speed that even the gods might have requested subtitles.

Professor Pixel placed his umbrella on the floor. It immediately spun in circles and pointed toward Dr. Halder’s medicine bag.

“Metal detected!” he cried.

“That is my forceps,” said the doctor.

“Science must begin somewhere.”

On the stone platform were carved words:

“Four witnesses must touch together.Law, faith, science, mischief.Then truth shall speak twelve times.”

Inspector Sen placed her hand in the first depression.

Gobindacharan placed his hand in the second.

Professor Pixel proudly placed his hand in the third.

Nolen hesitated.

“Will this arrest me?” he asked.

“No,” said Inspector Sen.

“Will this tax me?” he asked Pankaj, who had followed them secretly and was hiding behind Haru.

Pankaj emerged, embarrassed. “Tax structure will be discussed later.”

Nolen placed his hand in the fourth depression.

The platform trembled.

All twelve arches began to whisper.

“Gold sleeps where hunger was fed.”

“Gold sleeps where music became silence.”

“Gold sleeps where the river forgot its name.”

“Gold sleeps where the goddess sees but does not show.”

The whispers overlapped until the chamber sounded like a market full of invisible grandmothers.

Riki closed his eyes and listened carefully.

“Say them one by one!” he shouted.

The chamber obeyed.

The first arch said, “Count not doors. Count echoes.”

The second said, “The honest thief opens the dishonest lock.”

The third said, “The dead accountant remembers when numbers are sung.”

The fourth said, “The alien light reveals ink without fire.”

The fifth said, “The doctor hears what stone hides.”

The sixth said, “The priest must ring no bell.”

Gobindacharan looked offended. “No bell? Then why did I bring three?”

The seventh said, “The pradhan must promise nothing.”

Everyone looked at Pankaj.

Pankaj looked wounded. “Then what is my role?”

“Development restraint,” said Inspector Sen.

The eighth said, “The police must trust the child.”

Inspector Sen glanced at Riki. “I already do.”

Riki stood straighter.

The ninth said, “The scientist must switch off invention.”

Professor Pixel clutched his umbrella. “Cruel but visionary.”

The tenth said, “The ghost must forgive mango accounts.”

Panchanan became pale, which was impressive because he was already transparent.

The eleventh said, “The smugglers shall sneeze.”

From one of the tunnels came a loud sneeze.

“ACHOO!”

Then another.

“ACHOO! I am carrying a crowbar for illegal treasure extraction!”

The bell rang faintly.

“Boka Bali,” whispered Halder.

The twelfth arch said, “Beware the false treasure.”

Suddenly the chamber floor shook. From the canal-side tunnel emerged Boka Bali, Paltan, Chapal, and Titli, covered in mud and spiderwebs. Paltan held a crowbar. Chapal held a sack. Titli held a pistol, which made everyone instantly less amused.

“Enough drama,” said Boka Bali. “Map, clues, alien cube. Hand them over.”

Inspector Sen raised her revolver. “Drop the weapon.”

Titli smiled. “Madam, underground echoes confuse aim.”

Panchanan floated behind Boka Bali and shouted in his ear, “Debit entry pending!”

Boka Bali screamed and dropped his torch.

Zorbo pressed a button on his backpack. A beam of blue light filled the chamber. Hidden ink appeared on the walls, lines and arrows glowing like fireflies.

Riki saw that each arch had a number hidden above it. Not one to twelve, but old Bengali accounting symbols.

Panchanan gasped. “Ledger marks!”

The smugglers also saw the glowing arrows.

“There!” shouted Boka Bali. “That tunnel!”

Everyone ran at once.

Unfortunately, Professor Pixel forgot the instruction to switch off invention. His umbrella activated, shot sparks, opened, closed, opened again, and began dragging him toward the strongest metal source.

“Help!” he cried. “Science has become independent!”

The umbrella pulled him into the fifth tunnel. Dr. Halder chased him because medical ethics required preventing umbrella-related death. Gobindacharan chased the doctor because he had accidentally carried one of the bells. Nolen chased Gobindacharan because the bell was silver. Inspector Sen chased Nolen because habit is habit. Riki and Zorbo followed because the story had no choice. Panchanan floated behind complaining that nobody respected formation.

The tunnel ended in a locked iron gate.

On the gate was written:

“Dishonest lock. Honest thief.”

Nolen sighed. “Fine.”

He examined the lock. “This is not a lock. This is an insult.”

He took a hairpin from Gobindacharan’s hair knot.

“Arre!” cried the pujari. “That pin is ritual property!”

“Relax,” said Nolen. “It is becoming historical tool.”

Within seconds, the gate opened.

The chamber beyond was long and rectangular. Along its walls stood wooden chests.

Gold light shone from cracks.

Everyone froze.

Boka Bali burst in from another tunnel. “Mine!”

He ran to the nearest chest and opened it.

Inside were glittering gold coins.

Paltan opened another. Jewels flashed.

Chapal opened a third. Silver plates, ruby necklaces, emerald bangles.

Boka Bali laughed. “Treasure!”

He grabbed a handful of coins.

Immediately he sneezed.

“ACHOO! These are fake!”

The temple bell rang from far away though no one touched it.

Titli picked up a necklace and sneezed. “ACHOO! Glass stones!”

Paltan bit a coin and sneezed. “ACHOO! Brass!”

Chapal opened a chest and sneezed. “ACHOO! I fear my mother more than police!”

Inspector Sen smiled. “False treasure.”

Halder picked up a coin. “Stage props. Made to trap greedy men.”

Boka Bali growled. “Where is the real treasure?”

The chamber answered with an echo:

“Gold sleeps where hunger was fed.”

Riki remembered the old map. “Granary.”

Panchanan’s eyes widened. “The Lakshmi granary. During famine, Umaprasad opened grain stores. That was where hunger was fed.”

“But the map shows the granary tunnel collapsed,” said Halder.

Dr. Halder had his stethoscope pressed against the wall.

“Quiet,” he said.

Everyone stared. The doctor tapped the bricks and listened.

“There is a hollow passage behind this wall. Stone hides breathing.”

The fifth echo had said: the doctor hears what stone hides.

Zorbo scanned the wall. “Air cavity confirmed. Also two rats discussing inheritance.”

Panchanan moved behind Inspector Sen.

Nolen checked the bricks. “This section is newer. Someone sealed it.”

Boka Bali raised his pistol again. “Open it.”

Inspector Sen aimed her revolver. “Drop it.”

Then, from above, came a sound none of them expected.

“Moooooo!”

The retired cow had wandered down the stairs.

Behind her came half the village, including Pankaj Pradhan, who had gone up to give a statement and returned with supporters.

The cow saw Boka Bali waving a pistol. Perhaps she disliked weapons. Perhaps she remembered the tail incident. Perhaps she was simply a cow with principles.

She charged.

Boka Bali screamed, fired into the ceiling, missed everyone, dropped the pistol, and jumped into a fake treasure chest. The lid closed over him.

Inspector Sen arrested Titli and Paltan. Chapal surrendered to Gobindacharan and requested spiritual protection from cows.

Constable Haru looked at the cow with awe. “Madam, should we recruit her?”

“Already better than half my informers,” said Inspector Sen.

Riki, meanwhile, studied the sealed wall. A small carving showed a mango tree.

Panchanan whispered, “Mango accounts.”

The tenth echo had said: the ghost must forgive mango accounts.

Panchanan’s face changed. For a hundred years, he had been angry about the mango expenses that caused his last argument. He had accused the zamindar of wasting estate money on fruit gifts. He had died clutching the ledger, furious and unpaid.

Now he touched the mango carving.

“Umaprasad-babu,” he said softly, “perhaps the mangoes were for famine kitchens. Perhaps I was wrong. I forgive the account.”

The wall shook.

Brick by brick, it opened.

A dark passage sloped upward toward the granary.

At the end of the passage shone not gold, but a single brass lamp burning without oil.

Zorbo whispered, “That is not normal combustion.”

Panchanan smiled sadly. “No. That is from a lost world.”

Chapter 5: The Granary of Hungry Gods

The passage to the Lakshmi granary was lower than the earlier tunnels. Everyone had to bend except Panchanan, who floated smugly, and Zorbo, who was naturally compact.

The air smelled of old grain. On the walls were faded handprints, possibly of workers who once carried sacks during monsoon nights. Riki ran his fingers over them and felt a strange seriousness under all the comedy.

The Rajbari had been foolish, proud, quarrelsome, and dusty. But somewhere in its past, it had also fed people.

They reached a wooden door reinforced with iron strips. Above it was written:

“Do not open with hunger in your heart.”

Nolen stepped back. “I am always hungry.”

“Not stomach hunger,” said Halder. “Greed.”

Pankaj Pradhan raised his hand. “What about development hunger?”

The bell rang faintly.

Pankaj lowered his hand.

The door had no visible lock. Instead, it had seven small holes arranged like stars.

“Seven accounts,” whispered Panchanan.

From his ledger, he tore seven ghostly pages. Strangely, once separated from the ledger, the pages became solid. Each page carried numbers, grain quantities, names of villages, and payments made during hard times.

“The estate fed twelve villages,” said Panchanan. “Rice, dal, jaggery, oil. I entered every account.”

He placed the pages into the seven holes. Nothing happened.

Riki looked closer. “Numbers are not enough. The third echo said numbers are sung.”

Gobindacharan brightened. “Song! I can chant.”

“No bell,” warned Riki.

The pujari looked wounded again but obeyed.

Panchanan began to sing the account entries in an old cracked tune. It was not exactly music. It sounded like a calculator learning Rabindra Sangeet during a cold. But the granary door listened.

“Five maunds rice to Dakshinpara, Two jars oil to Banshtala, Seven sacks dal to Charaktala…”

As he sang, the holes glowed one by one.

Zorbo wiped his eyes.

“Are you crying?” asked Riki.

“No. My species leaks through antenna during agricultural emotion.”

The door opened.

Inside lay the old granary chamber.

It was vast, circular, and cool. Empty grain bins stood around the walls. At the centre was a raised stone platform. On the platform stood a wooden chest, simple and plain.

No gold glittered. No jewel flashed.

Boka Bali, still trapped in handcuffs, groaned. “After all this, one box? Very poor treasure management.”

Inspector Sen warned him to keep quiet.

The chest had four seals: a police symbol, a conch, a gear, and a small monkey.

“Law, faith, science, mischief again,” said Riki.

Inspector Sen touched the police symbol.

Gobindacharan touched the conch.

Professor Pixel touched the gear after promising not to switch anything on.

Nolen touched the monkey. “Why monkey?”

“Branding,” said Halder.

The chest opened.

Inside were bundles of old documents, a velvet pouch, and a smaller iron box.

Inspector Sen opened the pouch. Inside lay a necklace of gold and emeralds, a ruby nose-ring, diamond-studded bangles, a pearl belt, and gold mohurs wrapped in silk.

For once, nobody joked.

Even Nolen whispered, “Beautiful.”

Zorbo scanned the jewels. “Gold purity high. Emotional radiation very high. Snack value low.”

The iron box contained a letter written by Raja Umaprasad Choudhury.

Halder read aloud:

“If this treasure is found, know that it was not hidden to preserve luxury. It was hidden because men of greed had surrounded the estate. Part of it belongs to the temple, part to workers unpaid, part to famine relief accounts, part to education of children from the villages, and part to preservation of the house as public memory. Let no descendant claim all. Let no thief take all. Let guardians decide in daylight.”

Pankaj Pradhan became alert. “Guardianship committee?”

The bell rang.

“Daylight,” said Inspector Sen firmly. “Legal procedure first.”

But the story was not finished.

Professor Pixel, who had been unusually quiet, leaned toward the platform.

“There is something under this stone.”

Dr. Halder listened with his stethoscope. “Yes. Hollow again.”

Nolen found a hidden latch beneath the platform. “This one is not dishonest. It is shy.”

A square slab opened. Inside was a metal cylinder unlike anything in the Rajbari.

Zorbo’s antennae shot upward.

“That is not Earth-made.”

The cylinder glowed blue.

Panchanan stared. “I have never seen this.”

Zorbo carefully lifted it. His face became serious. “This is a memory capsule from my people.”

Everyone stared.

“Your people came here before?” asked Riki.

“Long ago,” said Zorbo. “Maybe one of my ancestors visited Earth, crashed, and was helped by this zamindar family. This capsule may be why my ship was drawn here.”

The cylinder projected a faint image: a green alien, older-looking than Zorbo, standing beside Raja Umaprasad in the granary. The alien held a broken engine part. The zamindar held a bowl of mishti doi. Both looked confused but friendly.

The projection spoke in a crackling voice.

“Record of Zorbo-Prime, explorer of Ulta-Palta Minor. Emergency landing on blue planet. Local human chief provided fermented sweet fuel and rice. In return, I helped create vault locks to protect community treasure. Warning: descendants may become foolish. Design accordingly.”

Zorbo bowed his head.

Riki whispered, “So your family helped hide the treasure.”

“Yes,” said Zorbo. “And your sweet yoghurt nearly destroyed two generations of navigation.”

This touching moment was interrupted by Boka Bali sneezing violently.

“ACHOO! I have a backup gang waiting outside!”

The bell rang like thunder.

Inspector Sen spun around. “Where?”

Boka Bali tried to hold his nose but the curse was stronger.

“ACHOO! Near the warehouse! With truck! And fake police uniforms! And one real goat for distraction!”

Inspector Sen immediately radioed for backup.

But before police could arrive, the ground shook. From the canal tunnel came shouting. The backup smugglers had entered and were trying to break through the old warehouse passage.

Dust fell from the ceiling.

Professor Pixel shouted, “Structural instability!”

Dr. Halder shouted, “Everyone breathe calmly!”

Gobindacharan shouted, “Can I ring bell now?”

“No!” shouted everyone.

Zorbo checked his device. “If they break the wrong wall, the granary may collapse.”

Riki looked at the layout projected by the alien cube. The smugglers were in the old river tunnel below them. If they could block the tunnel exit, police could trap them.

“How?” asked Inspector Sen.

Riki pointed to the grain chute system above the platform. “This granary used to pour grain down to storage channels. Can we open them?”

Panchanan smiled. “Yes. But there is no grain now.”

Nolen grinned. “There is fake treasure.”

The plan was ridiculous, which meant it had a high chance of success in Bhutum Bagan.

They carried the fake brass coins and glass jewels from the false treasure chamber to the grain chute. Professor Pixel connected his umbrella battery to the old pulley. Zorbo stabilised the mechanism with alien tape. Gobindacharan blessed the rope without bell. Dr. Halder stood ready with bandages. Panchanan floated through walls giving directions. Inspector Sen coordinated police positions. Riki counted down.

Below, the backup smugglers broke into the tunnel.

“Where is treasure?” one shouted.

“Above!” cried another.

At that moment, Riki pulled the lever.

A shining waterfall of fake coins, glass jewels, old brass plates, petrified luchis, and one unnecessary silver paan box nobody liked poured through the chute onto the smugglers.

They screamed.

“Gold!”

“Ow!”

“Diamond!”

“My nose!”

“Ruby!”

“Who threw luchi?”

The smugglers began fighting over fake treasure while sneezing truth.

“ACHOO! I betrayed you last month!”

“ACHOO! I kept extra commission!”

“ACHOO! I am not even a smuggler, I came for free dinner!”

By the time Inspector Sen’s police force entered from the warehouse, the gang had defeated itself through greed, slippery brass, and emotional confession.

The retired cow arrived last and sat at the tunnel mouth, preventing escape.

Constable Haru saluted her.

“Madam Cow has secured perimeter.”

The treasure was safe.

The smugglers were arrested.

The Rajbari was suddenly no longer sleepy.

But one final mystery remained.

The treasure letter mentioned “guardians in daylight.” Who were they?

At sunrise, as the team emerged into the courtyard, the first light touched the Durga dalan. The old temple bell rang once by itself.

On the floor before the goddess appeared a line of hidden writing, visible only in morning light:

“The final key is not below the house.It is in the house that children enter.”

Riki understood first.

“The old village school,” he said.

Panchanan nodded slowly. “Built from estate funds. Closed for years. The schoolhouse stands beside the banyan tree.”

Halder smiled. “Then the treasure has one more secret.”

Boka Bali groaned from the police jeep. “Again? This family hid things like squirrels.”

Zorbo looked delighted. “Good. My ship still needs repair. Also I have not studied school snacks.”

Chapter 6: The Gold and the Great Rosogolla Take-Off

The old Bhutum Bagan schoolhouse stood beside a banyan tree whose roots looked like an elderly committee discussing land records.

The building had two rooms, a broken blackboard, three benches, a portrait of Vidyasagar, and a cupboard full of exam papers from 1968. For many years, it had been closed. Children now went to schools farther away, while goats used the veranda for philosophical chewing.

The whole village gathered there after sunrise.

Inspector Sen placed police tape around the entrance. Pankaj Pradhan placed himself near the front, in case photographers came. Gobindacharan carried incense but no bell. Professor Pixel carried his umbrella under protest. Dr. Halder carried antiseptic, glucose, and suspicion. Nolen carried nothing, because Inspector Sen had checked.

Zorbo’s spaceship remained half-sunk in the Rajbari pond, guarded by Constable Haru and the retired cow.

Detective Halder examined the schoolhouse floor. “Children enter here. What did Umaprasad hide in a school?”

Riki walked to the blackboard. Faded chalk marks remained under layers of dust. He wiped them carefully.

A sentence appeared:

“Knowledge is the only treasure that grows when stolen.”

Nolen became emotional. “At last, theft with dignity.”

Below the sentence were four drawings: a book, a lamp, a grain stalk, and a star.

Panchanan touched the wall. “This school was Umaprasad-babu’s last project. Many relatives opposed it. They said poor children did not need learning. He said ignorance is more expensive than education.”

Pankaj Pradhan looked around nervously. “Good line. Can I use it in speech?”

The bell rang faintly from far away.

“No,” said Inspector Sen.

Riki noticed the portrait of Vidyasagar hung slightly crooked. Behind it was a small metal plate with seven screws.

Nolen approached. “May I?”

Inspector Sen nodded.

“With permission, theft becomes carpentry,” he said and opened the plate.

Behind it was a tiny switch.

Professor Pixel grew excited. “Let science press it!”

“No invention,” said Riki.

The scientist sighed and folded his hands.

Riki pressed the switch.

The blackboard slid upward.

Behind it was a hidden recess containing a second chest. This one was not full of jewels. It contained land deeds, handwritten scholarship lists, worker payment records, temple trust documents, and a small cloth bag of gold coins marked:

For school repair and village library.

Gobindacharan wiped his eyes. “The treasure was divided.”

Halder nodded. “Jewels in the granary. Future in the school.”

Inspector Sen collected the documents carefully. “These will need legal verification.”

Pankaj Pradhan said, “We shall form a transparent committee.”

The temple bell gave one sharp warning ring.

Pankaj coughed. “A very transparent committee. With minutes. Public display. External audit.”

The bell remained silent.

“Good,” said Inspector Sen.

Suddenly, Zorbo’s communication device beeped. He became alarmed.

“My ship core is losing sweetness.”

“Sweetness?” asked Dr. Halder.

“Mishti-doi radiation stabilised crash landing. But for take-off I need concentrated sugar-lactose joy. Preferably round, white, syrup-soaked.”

“Rosogolla,” said Riki.

The entire village became active. Within ten minutes, three sweet shops sent rosogolla. One sent pantua by mistake. Zorbo tested both.

“Rosogolla fuel acceptable. Pantua emotionally powerful but aerodynamically confused.”

Meanwhile, the arrested smugglers sat in a police van outside the schoolhouse. Boka Bali tried to look dignified despite having fake coins stuck in his hair.

Nolen walked up to him.

“See?” said Nolen. “This is why one should remain small thief. Big crime has logistics problem.”

Boka Bali sneezed. “ACHOO! I respect your professional analysis!”

The bell rang once in approval.

Later that morning, district police arrived. Heritage officials arrived. Reporters arrived. One reporter asked Zorbo whether aliens believed in democracy.

Zorbo replied, “We tried it once. Then three moons demanded separate parking.”

Detective Halder gave no interviews. He sat under the banyan tree with Riki and Panchanan.

“You solved most of it,” Halder told Riki.

Riki shook his head. “Everyone solved some part.”

“That,” said Halder, “is the secret of difficult mysteries. One person sees the clue. Another understands the clue. A third opens the lock. A fourth accidentally brings the cow.”

Panchanan looked at the schoolhouse. His old anger had disappeared. For the first time in a century, he did not clutch his ledger like a weapon.

“What will happen to me now?” he asked.

Zorbo said, “You can come to my planet. We need accountant ghost.”

Panchanan considered. “Do you have mango disputes?”

“Only floating pumpkin tax.”

“I will stay.”

Inspector Sen approached. “The heritage department wants someone to help catalog the Rajbari records.”

Panchanan straightened. “Finally. Proper employment.”

“You will be honorary archival guardian.”

“Salary?”

“You are dead.”

“Still exploited,” said Panchanan.

By afternoon, the treasure had been sealed under police supervision. The jewels would go through legal process. The school documents would help create a public trust. The Rajbari would not become a private resort, a smuggler warehouse, or Pankaj Pradhan’s International Alien Selfie Park, though he continued trying.

Nolen Das received a strange reward. Inspector Sen did not arrest him for old petty thefts, on condition that he return stolen objects and become a registered guide for the future Rajbari museum.

“Guide?” said Nolen.

“Yes,” said Inspector Sen. “You know every corner because you tried to steal from all of them.”

Nolen bowed. “At last, experience recognised.”

Gobindacharan became official temple custodian and promised never to sleep on the bell again unless spiritually necessary.

Dr. Halder wrote a medical paper titled Psychological Effects of Treasure Hunts on Mixed Human-Extraterrestrial-Ghost Groups, rejected by three journals before lunch.

Professor Pixel modified his umbrella into a “heritage detector.” It continued to detect only politics, forceps, and occasionally fried snacks.

At sunset, Zorbo prepared to leave.

The Rajbari pond had been cleaned enough for the spaceship to rise. The craft emerged covered in algae, one lotus, and a deeply offended frog.

The village gathered around.

Riki handed Zorbo a steel tiffin carrier.

“For the journey,” he said. “Rosogolla. And mishti doi. But careful.”

Zorbo took it solemnly. “I will warn my navigation system.”

Panchanan floated near the pond. “When you reach your planet, tell Zorbo-Prime’s descendants that Umaprasad kept his promise.”

Zorbo bowed. “And you kept the accounts.”

The spaceship door opened. Zorbo entered, then popped his head out.

“One question,” he said. “On Earth, are all mysteries solved by child, ghost, detective, thief, priest, doctor, police, scientist, cow, and local government?”

Detective Halder thought for a moment.

“In Bengal,” he said, “we prefer a full committee.”

The engine started. It sounded like a harmonium arguing with a pressure cooker. The ship rose slowly above the pond. Everyone waved.

The retired cow mooed.

Zorbo’s voice came through the speaker. “Farewell, chief fish and associated mammals!”

The ship shot upward, turned briefly toward the moon, then came back down two feet.

A hatch opened.

Zorbo shouted, “Forgot spoon!”

Riki threw one up. Zorbo caught it.

The ship finally vanished into the evening sky, leaving behind a trail of sparkling syrup vapour.

For several seconds, Bhutum Bagan was silent.

Then Pankaj Pradhan said, “We should build a commemorative gate.”

The temple bell rang angrily.

Everyone laughed.

Months later, the Rajbari became the Bhutum Bagan Public Heritage House. The old school reopened as a library and learning centre. The treasure helped restore the Durga dalan, repair village ponds, fund scholarships, and create a small museum.

At the entrance sat Nolen Das, now wearing a badge that said Authorised Guide.

His standard tour began like this:

“Ladies and gentlemen, please look at this pond. Here an alien fell. Please look at this temple. Here a ghost complained. Please look at this granary. Here smugglers sneezed truth. Please look at that cow. Do not argue with her. She is senior security.”

Panchanan floated in the archive room, correcting labels.

“No, no,” he would say to visitors. “That is not ordinary brass handle. That is three-eyed fish handle. Please respect accounting history.”

Inspector Sen visited sometimes, pretending to check security but actually to drink tea.

Dr. Halder visited to check whether ghosts required vaccination.

Professor Pixel installed a device at the gate that was supposed to count visitors. It counted clouds.

Gobindacharan rang the temple bell every evening, but softly. The bell had become famous and somewhat proud.

Detective Halder returned to his office above the tyre shop. On his wall he hung a framed note from Riki:

“Best mystery ever. Please call me for next case.”

A week later, Halder received a new client. A woman from Howrah claimed her pressure cooker was receiving messages from Mars.

Halder looked at the sky.

He smiled.

In Bhutum Bagan, under the banyan tree, Riki sat reading in the restored school library. Beside him lay the old copy of the treasure clue:

“The treasure belongs not to greed but to guardianship.”

He looked toward the Rajbari, glowing in the late afternoon sun.

Somewhere inside, a ghost was arguing with a file.

Somewhere outside, a reformed thief was charging five rupees extra for premium storytelling.

Somewhere in space, an alien was probably trying to explain rosogolla to his government.

And somewhere deep in Bengal’s endless lanes of dust, fishponds, temples, tea stalls, police registers, and impossible rumours, another mystery was surely waiting.

Because in Bengal, old houses never run out of secrets.

They only wait until a child, a ghost, an alien, and a detective have enough time after homework.

The End.
