THIS IS A WORK OF FICTION

On Saptami evening, when all of south Calcutta appeared to have dressed itself in borrowed gold and traffic police whistles, Nirmal Dey stood on a bamboo ladder above Rashbehari Avenue with a tester in his mouth and rainwater in his shoes.

Below him, the city performed its annual miracle of congestion. Autos nosed forward like green beetles. Buses breathed diesel into human faces. Aunties in silk saris lifted their hems over black water with the solemnity of queens crossing enemy territory. Boys with gelled hair and fake leather jackets shouted into the Puja noise as if shouting were a recognized form of courtship. Hawkers sold phuchka, balloons, plastic tridents, hair clips, devotional calendars, and phone covers printed with gods who had clearly not approved the artwork.

Above the tram wires and banners and loudspeakers, the pandal lights were supposed to bloom in sequence: conch, lotus, lion, goddess, demon, goddess again, because no Bengali committee trusted symbolism unless it repeated itself.

Instead half the avenue went dark.

“Dada!” screamed Tublu from below. “Committee secretary is coming. Please either fix or die before he arrives.”

Nirmal spat the tester into his palm. “Very good. Those are the two approved options in Bengal.”

He was fifty-one, thin in the manner of men who had known too many unpaid months and too much tea, with a cough that arrived whenever rich people spoke of opportunity. Once he had taught practical biology at a private coaching centre near Gariahat, telling boys with engineering haircuts that earthworms were nature’s humble ploughmen. Now he patched festival wiring, ceiling fans, mixer-grinders, and the occasional moral collapse of para committees. His wife had left for her brother’s flat in Barasat three years ago, taking their daughter’s framed photograph because, as she said, “At least there she will not gather damp.”

Their daughter, Piu, had died at eleven. Dengue, then negligence, then the great Indian fog in which nobody is responsible because everybody is busy.

Since then Nirmal distrusted water that collected.

He pushed aside a wet loop of wire and saw what had tripped the circuit. Not a burn. Not a rat bite. A skin.

It hung from the junction box, glossy black, thin as wet silk, ridged in rings. At first he thought it was rubber insulation peeled by heat. Then it moved slightly in the rain, not with the wind but against it, contracting with a private memory of muscle.

“Bring the torch,” he called.

“Torch gone,” Tublu said. “Volunteer took it to find his girlfriend.”

Naturally, Nirmal thought. Civilization had many stages, and the last was always a boy misusing equipment for romance.

He folded the black skin into newspaper and climbed down.

At street level an old man in a cream kurta was watching him. Not staring exactly. Studying. He had a scholarly head, bald on top, with a white fringe around it like defeated grass. His spectacles were taped at one hinge. In one hand he held a packet of muri; in the other, a plastic file swollen with papers.

“You found one,” the old man said.

“One what?”

The man looked at the newspaper in Nirmal’s hand. “Don’t throw it in the drain.”

“Why?”

“Because drains are how they learn the city.”

This was the sort of sentence Calcutta produced after sundown: philosophical, unhygienic, and possibly mad.

“Are you from the committee?” Nirmal asked.

The old man smiled. “No committee will accept me now. I am Dr. Arindam Lahiri.”

The name landed unpleasantly. Nirmal had seen it in old newspapers years ago. Not front page. Inside. Science scandal. Grant money. Failed wetland project. Some accusation about illegal specimens. The reporters had used the phrase “controversial geneticist,” which was newspaper Bengali for a man who had lost both reputation and furniture.

Tublu arrived without torch but with a paper cup of tea. “Dada, secretary says if lights don’t come in five minutes he will replace us with Behala team.”

“Tell him Behala team already died,” Nirmal said.

Dr. Lahiri leaned close. His breath smelled faintly of fennel and medicine. “Where is the skin?”

Nirmal held the newspaper tighter. “In my hand.”

“Good. Keep it dry.”

“It came from a wet junction box.”

“Yes. That is how things begin. Then they stop needing water.”

Across the avenue, lights failed again, not flickering but vanishing in strips. One lane after another. Conch. Lotus. Lion. Goddess. Gone. The darkness did not fall. It crawled.

People cheered at first, thinking it was part of the show.

That was Calcutta too. We are so starved for spectacle that catastrophe must introduce itself twice.

By Ashtami afternoon, the first missing reports had become para gossip. A goat from the meat shop near Lake Market. Two stray dogs. A boy’s sandal with the foot not inside it, discovered under a temporary bamboo gate. The police said open manhole. The committee said opposition sabotage. The opposition said ruling-party negligence. Everybody agreed the matter was unfortunate and therefore somebody else’s department.

Nirmal went to see Dr. Lahiri because the black skin had not dried.

He had kept it overnight on his table under the slow fan. In the morning it was damp, cool, and longer by two inches.

Lahiri lived behind an old single-screen cinema near Tollygunge, in a lane where posters peeled from walls in layers: gods, candidates, coaching centres, fairness clinics, lost pets, and one fading heroine smiling beneath mildew as if fame had become a fungal disease. His building had once been respectable, which in Calcutta meant the staircase was broad enough for former servants and current rats.

The door opened before Nirmal knocked.

Inside, Lahiri’s flat was nearly empty. Books stood in towers where furniture should have been. A cracked aquarium occupied one wall, green with algae. The air smelled of wet soil, stale incense, and the mineral coldness of underground places.

“You brought it?” Lahiri asked.

“No. I came for tea.”

The old man looked puzzled.

“Yes, I brought it.”

Nirmal placed the newspaper on a table. The skin inside flexed, very gently. Lahiri shut his eyes.

“How many?” Nirmal asked.

“Outside? I don’t know.”

“Inside?”

“That is not a simple question.”

“It becomes simple if police ask.”

Lahiri laughed softly. “Police. My dear man, police cannot find stolen scooters parked outside police stations. You want them to find the Ordovician?”

Nirmal did not like educated madness. Uneducated madness shouted and broke cups. Educated madness quoted time periods.

“You made them,” he said.

“I brought back a possibility,” Lahiri replied. “Modern worms are modest because the world became modest. Oxygen fell. Soil changed. Predators improved. Everything was reduced, domesticated, disciplined. But once, before vertebrate arrogance, the earth belonged to soft bodies and appetite.”

“Very poetic. Did one eat the goat?”

“They do not eat like tigers. They incorporate.”

“Excellent. The goat will be pleased to hear its promotion.”

Lahiri’s mouth twitched. For a moment he seemed almost ordinary, an old Bengali man enjoying sarcasm in a failing room.

Then something thudded under the floor.

Nirmal looked down.

“Neighbour?” he asked.

“No.”

Another thud. Slow, muscular, patient.

Lahiri moved to the aquarium and lifted a damp cloth from its top. Inside, there was no fish. There was mud, black water, and a small shrine photograph of a boy of about twelve, smiling with one front tooth slightly crooked.

“Your son?” Nirmal asked before he could stop himself.

Lahiri covered the aquarium again.

“Riju,” he said. “He liked earthworms. Other boys wanted dinosaurs, tigers, aeroplanes. Riju wanted things people stepped over.”

Nirmal thought of Piu’s photograph in Barasat, wrapped in newspaper on a steel almirah perhaps, between saris and school certificates nobody could throw away. Grief made fools of people. That was its oldest scientific property.

“You lost him,” Nirmal said.

“Everybody loses someone. Only the rich get to call it tragedy. The rest call it adjustment.”

There it was, sharp and bitter, a true thing made poisonous by being kept too long.

“What did you teach them?” Nirmal asked.

Lahiri did not answer.

The floor thudded again. This time dust fell from the bookshelf.

On Ashtami night the crowds thickened until the city became a single animal with many elbows. Nirmal worked near Deshapriya Park, checking distribution boxes, sweating through his shirt though the air had turned strangely cool.

Everywhere there were clues now, once he knew how to see them. Wet circles on dry asphalt. Drains breathing mist. Bamboo poles darkening at the base as if dipped in ink. Dogs refusing lanes. Crows gathering on cable lines but not cawing. Near a tea stall, a length of marigold garland lay on the ground and slowly disappeared through a crack no wider than a coin slot.

He called Tublu. “Stay off drains.”

“Why?”

“Because I said.”

“That is not information, dada. That is parenting.”

“Then consider yourself raised.”

The lights failed at eight twenty-three.

Not all. That would have been less frightening. Instead the city lost illumination in patches, like a body losing sensation. A pandal blazed white, then next to it a lane disappeared, then a restaurant sign, then the fairy lights on a balcony where an old woman stood holding a plate of incense. The dark portions were not empty. They moved.

People began to scream when the first bamboo barricade bent inward.

From the mouth of the lane came a rolling blackness, low at first, then rising, braided, wet, ringed, thousands of bodies sliding over and under one another. It looked like smoke until one saw the shine. It looked like cloth until one saw the mouths. It looked like a single creature until one saw it deciding in many directions at once.

The worms came soundlessly except for a soft dragging, like wet saris pulled across stone.

A man in a new kurta slipped. His wife grabbed him. Something black wrapped his ankle. Nirmal struck it with a bamboo pole. The thing recoiled, not from pain perhaps, but from surprise. Its body was thick as a child’s thigh and cold as stored rain.

“Move!” Nirmal shouted.

That useful human instruction, ignored by crowds everywhere since the invention of crowds, finally worked when a goddess’s lion toppled and smashed into the street.

People surged toward the main road. Children cried. Someone dropped a dhaak. The drum rolled, was covered, and stopped.

Above the chaos, through a loudspeaker still powered by some separate line, a recorded chant continued in perfect devotion.

Nirmal saw Dr. Lahiri standing beside a transformer, calm, file under one arm.

He pushed through the crowd toward him. “Stop this!”

Lahiri watched the black mass enter the light. “I cannot.”

“You released them.”

The old man’s eyes shone. “No. They left.”

“That is what all fathers say about children who become criminals.”

Lahiri flinched, and Nirmal was ashamed of the cruelty because it had come from his own wound, not from justice.

A worm lifted its front end near Lahiri. No eyes, no face, only a blunt opening that trembled in the air. Lahiri whispered something.

The worm turned toward him.

Nirmal heard it then.

Not from the worm. From below. From drains, cracks, gutters, wet soil around trees. A sound like thousands of mouths forming a name without breath.

A-rin-dam.

The old man smiled with terrible tenderness.

“You made them remember you,” Nirmal said.

“No,” Lahiri whispered. “I made them remember being called.”

“Called by whom?”

Lahiri looked at the black river spreading beneath Durga’s painted feet. “By whoever loved them first.”

The next hour broke into pieces.

Nirmal dragged three children onto the roof of a sweet shop. He saw Tublu standing on a taxi bonnet, swinging a broken light frame like a sword and shouting, “Come then, biology!” which was brave, stupid, and therefore almost noble. He saw a policeman firing into the ground until his bullets vanished into moving flesh without effect. He saw one worm climb a lamp post and wrap around the light, not to break it but to cover it, as if darkness were not absence but appetite.

Then Nirmal saw the pattern.

They avoided loudspeakers playing devotional songs. They crossed roads where names were being shouted. A mother screamed “Bappa!” and the black surface rippled toward her voice. A man yelled “Munni!” and three thick cords rose from a drain. The worms did not hunt heat. They hunted address.

Calcutta, which had survived empire, famine, ideology, real estate promoters, and committee meetings, was being undone by its greatest habit: calling out to missing people.

Nirmal found Lahiri near the rear of the pandal, half fallen against bamboo.

“Where is the wetland?” Nirmal demanded.

Lahiri’s face had gone grey. “Under the old tram depot.”

“There is no tram depot there now.”

“Exactly. There is a luxury complex proposal. Basement work stopped in litigation. Water came in. I improved it.”

“How many are there?”

Lahiri laughed, then coughed. “In Bengal? Count complaints. Same number.”

Nirmal slapped him. Not hard. Enough to bring him back from poetry.

“How to stop them?”

The old man touched his cheek, astonished. “You can’t kill them tonight.”

“Then what?”

“Call them home.”

“To you?”

Lahiri looked toward the moving dark. “They know my name. But not home.”

“Who does?”

Lahiri closed his eyes. “Riju.”

The hidden wetland lay beneath a construction fence behind a row of shuttered shops, where a billboard promised “LUXURY NATURE LIVING” above a pit filled with illegal rain. The irony was so Bengali it should have received a state award. Vines had eaten the scaffolding. Mosquitoes rose in committees. From below came a wet turning sound, immense and intimate, as if the earth had digestion.

Nirmal reached it with Lahiri leaning on him and Tublu limping behind.

“You should go,” Nirmal told the boy.

“And miss this?” Tublu said, eyes huge. “Dada, my whole life is boring. Let me have one apocalypse.”

They climbed through a gap in the fence.

The basement ramp descended into black water. But it was not water. Not entirely. The surface breathed in rings. Dim emergency lamps, rigged along the walls, showed an artificial marsh spread under concrete columns: reeds, tanks, mud channels, pipes, prayer flags of scientific tape, and everywhere black bodies moving through one another, soft and muscular, ancient as hunger.

At the far end stood a small wooden platform. On it: a schoolbag, a rusted cricket bat, a plastic dinosaur, and dozens of notebooks sealed in transparent covers.

Riju’s things.

“You kept a shrine,” Nirmal said.

“A memory chamber,” Lahiri whispered.

“You kept a shrine.”

The old man said nothing.

From the city above came shouting, metal buckling, the far rhythmic chant of Puja continuing because devotion, like bureaucracy, rarely stops merely because reality has objected.

Lahiri opened the plastic file and pulled out a notebook. Its pages were covered in childish handwriting. Drawings of worms. Labels. Names. Not scientific names. Pet names.

Moti. Kalo. Bhulo. Raja. Professor. Maati-babu.

On the last page, written many times in larger letters: Riju.

“They responded to his voice recordings,” Lahiri said. “At first only movement. Then pattern. Then preference. I thought memory had entered them. Not human memory. Older. Associative. Name as food bell. Name as sunlight. Name as home.”

“You used your dead son’s voice to train them.”

“I used what was left.”

The sentence was almost too small for the crime.

Nirmal thought of all that remains after a child dies. Hairclips. Geometry boxes. Half-used soap. The last water bottle. A parent can turn anything into a temple because the alternative is admitting the universe has no complaint department.

“What happened to Riju?” Nirmal asked.

Lahiri looked at the wetland. “He drowned in monsoon water beside an open construction pit. This pit. Before the project changed hands. Before the wetland. Before everything.”

“And nobody was punished.”

“Nobody is ever punished. They are transferred, promoted, garlanded, or elected.”

There was the social law of the city, stated with scientific economy.

A tremor passed through the marsh. From the ramp behind them, the worms began returning, pouring down from the streets in thick black ropes. They had heard Lahiri. Or the notebook. Or grief itself speaking.

Tublu backed away. “Dada.”

The first mass reached the platform. It rose, bodies weaving, tasting the air.

Lahiri stepped forward with the notebook open. “Riju,” he called.

The wetland stopped.

For one second, all of it listened.

Then the black surface surged toward him.

Not angrily. Joyfully.

That was worse.

Nirmal grabbed Lahiri’s arm, but the old man pulled free with surprising strength. “No. Let them come.”

“They’ll take you.”

“They were always coming.”

The worms climbed him in loops. He did not scream. He held the notebook above the mass like a priest with scripture until a thick body wrapped his chest and drew him down to his knees.

“Nirmal,” he gasped.

It was the first time he had used his name.

Nirmal stepped back.

The wetland stirred.

Again that breathless murmur rose, uncertain, testing.

Nir-mal.

He understood then with a coldness that went beyond fear.

The skin in the junction box had not come to him by accident. Lahiri had not approached him because he was an electrician. The worms had followed the black skin because Nirmal had carried it home, had spoken beside it, had slept near it, had whispered Piu’s name at dawn when he thought no one, not even God with his famously poor administrative record, was listening.

Ordinary clues, cruelly patient.

The wetland knew him too.

Lahiri sank to his waist. “Names,” he said, with difficulty. “Don’t give them names.”

From Tublu’s pocket came a small sound.

Not a phone. A plastic whistle, the kind Puja volunteers used to move crowds while achieving nothing.

Nirmal snatched it and blew.

The shrill note cut through the basement. The worms recoiled, not fleeing but confused. No name. No love. No summons. Pure command without memory.

“Blow and run,” Nirmal told Tublu.

“What about you?”

“Today I am Behala team. Already dead.”

“Dada—”

“Go!”

Tublu blew the whistle until his face reddened and stumbled up the ramp. The worms shifted toward the sound, then away, baffled by its namelessness.

Lahiri was almost gone. Only his head and one hand remained above the moving black. His expression was not peaceful. Peace is what outsiders invent for the dead so they can sleep. His face was hungry, terrified, grateful, ashamed.

“Say his name,” he begged.

Nirmal knew what that would do. It would call the whole wetland upward. It would bring them through every drain, every crack, every Puja lane where mothers were still shouting for children. It might give Lahiri one final illusion of reunion and Calcutta a night it would never climb out of.

He also knew the cruelty of refusing a father his dead child’s name.

He bent, picked up the plastic dinosaur from the platform, and pressed it into Lahiri’s remaining hand.

“No,” Nirmal said. “You remember him. That is enough.”

For a moment the old man hated him.

Then the worms covered his mouth.

Nirmal took the notebook and ran.

At the ramp he stopped once and looked back. The wetland was folding inward around the platform. The worms moved over Lahiri, over the schoolbag, over the cricket bat, over the place where a boy had been turned into research because grief had found a laboratory and no one had come in time to switch off the lights.

Nirmal climbed out into the Puja night and began tearing pages from the notebook.

He did not burn them. Fire attracted crowds. He chewed each page into pulp and spat it into a bucket of bleaching powder outside a closed pharmacy. It was undignified, disgusting, and possibly the most useful work he had done in years.

By dawn, the lights returned in pieces.

The city invented explanations quickly. Gas leak. Drain collapse. Illegal tunnelling. Political conspiracy. Viral panic. A minister visited one site in white clothes and did not step in mud. Newspapers used words like “stampede-like situation” because language, too, avoids responsibility when properly trained.

Tublu survived with two broken toes and became briefly famous in the para for fighting “something like cable wire but angry.” The committee refused to pay extra because apocalypse had not been in the contract.

Nirmal went back to his room and found the table dry. For the first time since Piu’s death, damp had retreated from one corner of the wall.

He should have felt relief.

Instead, near noon, as the city slept off terror and incense, he heard a soft movement inside the drain below his window.

Not crawling.

Waiting.

He held his breath.

From the pipe came a whisper made of mud, hunger, and impossible patience.

Pi-u.

Nirmal closed the window gently, as one closes a door on a child who must not be woken.
