If you have ever wandered through the older lanes of Kolkata on a winter evening, you may have felt it—the strange hush that falls after sunset, when the city seems to remember something it would rather forget.
It was on such an evening that I met Taranath Tantrik again.
He was seated in a dim tea shop near Shobhabazar, wrapped in a frayed shawl, warming his hands over a clay cup of tea. His eyes, sharp as ever, lifted when I approached.
"You have come for a story," he said before I could speak.
I smiled. "Or perhaps for proof."
He laughed softly. "Proof is for courts. I deal in experience."
That night he told me about the Lantern in the Fog.
Years ago, a railway officer from a small town near the Bengal–Bihar border came to Taranath in desperation. The officer was an educated man, practical and disciplined. Yet for three weeks, every night at exactly one o'clock, he saw a lantern glowing on the abandoned railway bridge outside town.
The bridge had been closed after a tragic accident decades earlier. A train had derailed in heavy fog, plunging several compartments into the river below. Many passengers drowned before help arrived.
Since then, villagers claimed that on fog-heavy nights, a lantern moved slowly across the bridge—back and forth—as though someone were guiding a train that would never come.
The officer did not believe such tales. But he had seen it himself. Worse, the lantern seemed to pause and flicker toward his quarters, as if beckoning him.
Taranath agreed to visit.
They reached the town on a moonless evening. The air was thick with mist. Even the sound of crickets seemed muffled. At midnight they walked toward the bridge.
The river below flowed dark and silent.
At one o'clock precisely, the fog deepened. And then—there it was.
A faint golden light at the far end of the bridge.
It swayed gently, like a lantern carried by an unseen hand.
The railway officer gripped Taranath's arm. "You see it?"
Taranath nodded calmly.
The lantern began to move across the bridge, slow and steady, stopping every few steps. As if checking tracks. As if waiting for something.
Taranath closed his eyes and whispered a mantra under his breath. The air grew colder.
When the lantern reached the center of the bridge, it stopped. The flame flared brighter. And for a brief second, a shadow formed around it—a silhouette of a man holding the lamp high, scanning the fog.
A railway signalman.
Taranath stepped forward boldly. "Your train has passed," he called into the mist. "Your duty is over."
The lantern flickered violently. The fog seemed to swirl in agitation. A faint sound rose from the river below—not a scream, not quite wind—something between memory and sorrow.
The officer stood frozen.
Taranath took a small brass bell from his bag and rang it three times. The clear metallic sound cut sharply through the fog.
"You guarded the dead," he said firmly. "But they have gone. Why remain?"
The lantern dimmed.
Slowly, the shadow lowered its arm.
And then, like a fire starved of air, the light went out.
The fog thinned almost immediately.
They waited. No light returned.
The railway officer later confirmed that the lantern was never seen again. The villagers whispered that the old signalman's spirit had finally left his post.
When Taranath finished the story, the tea shop had nearly emptied.
"Do you believe it?" he asked me quietly.
"I don't know," I admitted. "Why would a spirit continue such a duty?"
Taranath smiled faintly.
"Habit," he said. "The living are not the only ones bound by it."
Outside, the fog had begun to gather in the narrow lane. And for a brief moment, as I stepped into the night, I found myself searching the distance for a moving light.
