The hour was indecent. A faint knocking, sharp and deliberate, stirred Edmund Harrow from the papers spread across his desk. His lodging was modest, the single candle sputtering against the heavy night pressing at the windows. The clock upon the mantel had just chimed midnight. Few dared call at such an hour.
The knock came again.
He rose, slipping on his coat, every sense alert. London nights had a way of carrying menace in their silence. When he pulled open the door, the passage beyond was empty—save for a single envelope, pale against the worn wooden boards.
Edmund bent, picked it up, and turned it over in the dim light. The wax seal bore no crest, no family insignia, only a crude impression as though pressed by a thumb. His fingers itched with unease.
Inside, the letter was scrawled in a hand uneven, almost fevered:
"Debts are not forgotten. What is owed shall be taken. Every truth you bury grows teeth. Balance will be restored. And you—detective—will taste the cost of your own blindness."
There was no signature.
Edmund read the lines twice, three times, brow furrowed. His cases had made enemies—thieves, extortionists, violent men dragged before the magistrates. But this… this bore the weight of obsession, not revenge of the ordinary sort. The phrasing was strange, as though written less to threaten than to prophesy.
He sat long into the night, staring at the words, searching memory for some forgotten slight, some dismissed case. Nothing came. At dawn, weary and unsatisfied, he tossed the letter into the fireplace and watched the flames consume its secrets.
"Some prank," he muttered to himself. "Some criminal's crude attempt to unsettle me."
And so he dismissed it.

A Week Later
The air was gentler, though still damp with London's winter fog. Edmund had taken to walking the park in the afternoons, seeking respite from his own restless thoughts. Children laughed distantly near the pond, their kites trembling in the pale sky.
Edmund sat upon a bench, notebook in hand, though the pages remained blank. The week had been restless—dreams unsettled, concentration broken. The image of that uneven handwriting had refused to release him.
He was roused from his reverie by a presence at his side. A boy, perhaps ten, thin as hunger itself, stood nervously clutching a folded paper. His cap sat crooked, his boots too large for his feet.
"Sir," the boy said, hesitant. "Are you… are you the detective?"
Edmund narrowed his eyes. "Why do you ask?"
The boy swallowed, shifting from foot to foot. "A man told me. Said I'd find you here. Said… said to give you this." He extended the paper with both hands, as though it weighed far more than it should.
Edmund accepted it slowly. "What man?"
The boy's gaze darted over his shoulder, into the curling fog. "Tall. Wore a hat. Didn't see his face proper. But his voice… it was soft. Strange. After he gave me the paper, he just… gone. Like smoke."
Edmund's pulse quickened, though his features remained composed. He drew a shilling from his pocket, pressing it into the boy's palm. "Go home, lad. Quickly."
The boy nodded and scampered away, disappearing into the mist from which he had come.
Edmund unfolded the paper.
Only one word sprawled across it, jagged and dark, as though carved in ink rather than written:
FOOL
The letters stared back at him like an accusation.
He felt his breath quicken, the air grow tighter. Fool. Was it insult, confession, or signature? He looked around—the park, the fog, the trees. Every shadow seemed to lean closer.
Then it came.
A low thunder, distant yet powerful, shuddered through the ground. Birds shrieked from the trees, scattering into the air. Edmund rose to his feet, heart hammering, eyes cast toward the horizon.
There—beyond the haze—rose a plume of smoke, black and rolling, clawing into the winter sky. The sound came again, sharper, violent—an explosion. And the direction was unmistakable.
The police station.
His mind reeled, grasping at reason, but none came. His colleagues, men he had worked beside only days ago…
The world seemed to tilt. The paper crumpled in his hand, the single word burning in his mind.
FOOL.
And as the sirens of chaos began to rise in the distance, Edmund Harrow stood in the lonely fog of the park, unable to tell whether the word named him, warned him, or condemned him.
