The disappearance of Anirban transformed the mansion once again into a place of unease.
Only a day earlier, the Bhattacharjee mansion had seemed finally free from its long shadow of terror. The mystery of the hidden passages had been uncovered. The murders appeared solved. The cursed fountain pen had supposedly vanished forever beneath the dark waters of the pond.
But by dawn, fear had returned.
Servants whispered nervously in corridors. Doors remained shut. Even the old grandfather clock in the drawing room sounded heavier than before, each tick echoing through the silent mansion like a warning.
Police searched the estate thoroughly but found no trace of Anirban.
They checked every room, every locked cabinet, every hidden passage Professor Jones had discovered behind the walls. Officers searched the gardens with lanterns despite the muddy ground left behind by the storm.
Nothing.
"It's impossible," Karn muttered. "The room was locked from outside."
Professor Jones stood near the doorway of Anirban's chamber, examining the surroundings carefully. His sharp eyes moved slowly across the cracked walls, dusty shelves, and damp wooden floorboards.
"No," he said quietly. "Not impossible."
He walked toward the far wall beside the window and pointed toward faint scrape marks near the stone surface.
"The hidden passage connects here as well."
Martin leaned closer and finally noticed what Jones had seen. Tiny scratches disturbed the layer of dust near the base of the wall.
Martin exhaled slowly.
"So he escaped during the storm."
"Most likely."
Outside, thunderclouds still hung low across the grey morning sky. Rainwater dripped steadily from the roof edges of the mansion.
Rudra Babu appeared deeply shaken. Overnight, the old man seemed to have aged several years. Dark circles surrounded his tired eyes.
"I thought everything had ended."
Jones looked thoughtful rather than worried.
"Not yet."
The professor's calmness unsettled Martin more than panic would have.
That afternoon, Martin found Jones sitting alone inside the library. Dusty sunlight filtered weakly through the tall windows while the professor studied the old confession written by Rai Bahadur Hemendra Narayan.
The paper looked fragile with age. Brown stains covered the edges, and the ink had faded in several places.
"You think there's more?" Martin asked.
Jones tapped the document gently.
"This letter mentions something strange."
Martin leaned closer.
"'The pen must never fall into the wrong hands, for the final list remains hidden.'"
Jones adjusted his spectacles.
"The final list?"
Martin frowned.
"We assumed the pen only concealed the treasury code. But what if there was something else?"
The professor turned another page thoughtfully.
"Rai Bahadur Hemendra Narayan was a careful man. Men like him rarely choose words carelessly."
Before Martin could reply, Karn entered the room hurriedly, breathing heavily.
"Professor! Someone saw Anirban near the old railway warehouse outside town."
Jones stood immediately.
"Who saw him?"
"A tea seller near the station. He recognized Anirban from the police descriptions."
Martin felt tension rise instantly.
"Then he's still carrying the pen."
"Perhaps," Jones replied quietly.
Within an hour, they reached the abandoned structure near the railway tracks.
The warehouse stood isolated beneath a grey evening sky. Rusted railway lines stretched endlessly into the distance like dark scars across the earth. Wild grass grew through broken stones around the building.
Broken windows rattled in the wind.
A loose iron sheet clanged repeatedly somewhere above them.
The place felt abandoned not only by people, but by time itself.
Karn spoke softly.
"The police are on their way."
Jones nodded.
"Good. But until then, we proceed carefully."
The wooden warehouse door creaked loudly as they entered.
Inside, dust floated through pale shafts of evening light. Stacks of rusted machinery stood like giant shadows across the enormous room. Old crates lay overturned near the walls.
And there, beside a cracked wooden table, stood Anirban.
In his hand…
The pen.
Martin stared in disbelief.
"But Rudra Babu threw it into the pond!"
Anirban smiled weakly.
"I retrieved it before dawn."
His face looked exhausted. Almost feverish.
His clothes were damp and stained with mud. His eyes appeared hollow from sleeplessness. Yet beneath the exhaustion, Martin could still see something dangerous lingering within him.
Jones stepped forward slowly.
"You risked everything for that pen?"
Anirban laughed softly.
"At first, yes."
"You still think it contains wealth?" Jones asked.
"No."
Anirban's voice trembled strangely.
"I found something else."
For a moment, silence filled the warehouse except for the distant sound of approaching rain.
Then Anirban carefully unscrewed the barrel of the fountain pen.
From inside, he removed a tightly folded piece of paper.
Martin stared in shock.
"There was another compartment…"
Jones accepted the folded paper carefully and opened it beneath the dim warehouse light.
His expression changed instantly.
Names.
A list of names.
Freedom fighters.
Informants.
British collaborators.
Beside several names were handwritten notes in Bengali and English. Dates. Places. Payments. Betrayals.
Martin realized the truth first.
"This isn't a treasure record."
Jones nodded grimly.
"It's evidence."
The Rai Bahadur had secretly documented British agents and Indian collaborators during the independence movement.
Some names belonged to forgotten revolutionaries executed by colonial authorities decades earlier. Others belonged to wealthy businessmen and influential landowners whose descendants still possessed power and status in Bengal.
Martin suddenly understood why Hemendra Narayan had hidden the list so carefully.
This was no ordinary secret.
It was political poison.
Anirban laughed bitterly.
"Do you understand now? Even after all these years, these names matter. Some descendants are still influential."
Karn looked horrified.
"You wanted to sell this information?"
"No."
Anirban lowered the pen slowly.
"I wanted leverage. Protection. A way out."
The wind outside grew stronger. Rain began striking the broken windows.
Martin studied Anirban carefully.
For the first time, he no longer looked like a calculating criminal. He looked trapped. Cornered by fear, greed, and desperation.
Jones stepped forward carefully.
"And instead?"
Anirban looked suddenly broken.
"Instead I became exactly what this family always feared."
His voice cracked during the final words.
For several seconds, nobody spoke.
The warehouse seemed frozen in silence.
Then Anirban slowly sat down beside the crate, staring at the pen in his hand.
"When I first discovered the hidden passage," he whispered, "I only wanted the treasure."
His tired eyes drifted toward the floor.
"But once I found the list… everything changed."
Martin remained silent.
Anirban continued speaking almost as though confessing to himself.
"I thought the information could protect me. Powerful people fear secrets more than weapons."
Jones listened quietly.
"But fear changes people," Anirban said. "It changed me."
Karn's face hardened.
"You murdered innocent people."
Anirban closed his eyes briefly.
"I know."
A deep sadness settled over the warehouse.
Martin suddenly remembered the frightened servants, the bloodstained corridors, the terrified whispers about a cursed pen killing members of the household one by one.
All of it had begun not with ghosts or supernatural evil—
but human weakness.
Greed.
Fear.
Desperation.
Anirban placed the pen gently on a wooden crate nearby.
"I'm tired."
In the distance, police sirens echoed faintly through the rainy evening.
Karn had informed the authorities before leaving town.
Anirban heard the sirens too.
Yet he made no attempt to escape.
Perhaps he understood there was nowhere left to run.
"I never intended to kill anyone at first," he whispered. "But once fear begins controlling people… it spreads like poison."
Jones said nothing.
Because there was nothing left to say.
The police arrived minutes later.
Flashlights cut through the darkness inside the warehouse while officers surrounded the building cautiously.
Anirban surrendered peacefully.
No struggle.
No resistance.
As officers handcuffed him and led him toward the exit, he paused once and looked back toward the pen resting silently on the crate.
For a brief moment, Martin thought Anirban wanted to say something more.
But he did not.
Then he disappeared into the rain.
The next day, Professor Jones prepared to leave Cooch Behar.
The Bhattacharjee mansion seemed strangely lighter now.
Curtains were opened for the first time in days. Sunlight entered rooms that had once felt dark and suffocating. Servants moved through the corridors without fear.
Even the air itself felt calmer.
Martin stood near the entrance hall watching workers clean dust and broken furniture left behind during the investigation.
"It's strange," he said quietly. "The mansion feels different."
Jones smiled faintly.
"Houses often reflect the minds of the people inside them."
Outside, luggage was already loaded into the waiting car that would take them to the railway station.
Rudra Babu met them at the entrance.
The old man folded his hands respectfully.
"You solved the mystery," he said quietly.
Jones smiled.
"Not entirely. Human beings remain far more mysterious than any object."
Rudra Babu nodded slowly.
Pain still lingered in his expression, yet so did relief.
"What will happen to the pen?"
Jones glanced toward Karn.
"That decision belongs to the family."
Karn stood silently for several moments holding the black fountain pen in his hand.
The object looked harmless now.
Small.
Ordinary.
Yet it had destroyed lives, uncovered buried truths, and awakened decades of fear.
At last Karn spoke.
"We will donate it to a museum with the documents. Let history remember the truth instead of the legend."
Rudra Babu smiled faintly.
For the first time since their arrival, peace appeared in his eyes.
Later that evening, Martin and Professor Jones boarded the train back to Kolkata.
The train slowly pulled away from the station as rainclouds drifted across the fading sky.
Martin leaned back into his seat with relief.
"So the killer pen was never supernatural after all."
Jones lit his pipe thoughtfully.
Smoke curled upward beside the window.
"My dear Martin, very few things are."
Martin smiled tiredly.
"Then what truly killed those people?"
Jones watched the countryside drift past beyond the rain-covered glass. Villages, trees, and distant rivers faded into the approaching evening mist.
For a long moment, he remained silent.
Then he replied softly:
"Greed."
The rhythmic sound of the train wheels echoed through the compartment.
Outside, darkness slowly covered the Bengal countryside.
And far behind, in the fading grandeur of the Bhattacharjee mansion, the legend of the killer pen finally came to an end.
