Chapter 41: THE KEY IN THE DARK
The key was cold enough to burn.
Konrad stood at the garden's edge, the river roaring below, and turned the iron over in his palm. It was a simple thing—no ornament, no mark—the kind of key that opened servants' doors and secret passages, the kind that was never meant to be found.
Eliska had given it to him without explanation. The chamber is locked. The guard changes at midnight. You have until the bells of St. Vitus.
He had no idea what the chamber held. That was the point, he realised. She was testing him—not his courage, but his curiosity. A man who asked no questions was a man who could be trusted with answers. A man who asked too many was a man who ended up in the river.
The river takes what it takes.
Konrad slipped the key into his tunic and walked back toward the castle, the snow crunching beneath his boots. The feast would be ending soon. Ottokar would expect him to appear, flushed with wine and gratitude, ready to be tested again.
But the night was not over.
---
The corridors of Prague Castle were a maze of shadow and candlelight. Konrad moved through them with the ease of a man who had spent months learning their turns, their alcoves, their hidden doors. He had mapped this fortress in his mind the way a surgeon maps a body—knowing where to cut, where to stitch, where to leave well enough alone.
The key was for a door in the eastern tower, a narrow spiral staircase that led to rooms the servants called the *staré komnaty*—the old chambers. Rooms that had been sealed since the fire of 1269, when a candle had tipped and taken half the tower with it.
Or so the story went.
Konrad paused at the base of the staircase, listening. Above him, the wind moaned through the tower's joints, and somewhere in the distance, he heard the faint strains of the feast—a lute, a woman's laugh, the low rumble of men who had drunk too much and would say too much before the night was done.
He began to climb.
The stairs were narrow and worn, the stones slick with centuries of damp. The air grew colder as he rose, and the smell of smoke grew stronger—old smoke, the ghost of a fire that had been extinguished years ago but had never quite left.
The door at the top was oak, banded with iron, and it bore the scars of the fire—blackened streaks along the grain, a corner where the wood had charred and been planed smooth. The lock was new, however, bright and untarnished, and it gleamed in the light of his candle.
Konrad fitted the key into the lock. It turned with a click that seemed louder than it should have been, a sound that echoed down the staircase like a stone dropped into a well.
He pushed the door open.
---
The room beyond was not a chamber. It was a tomb.
Dust lay thick on every surface—on the heavy oak table, on the chairs pushed against the walls, on the tapestries that hung crooked and grey with age. The windows were shuttered, the shutters nailed fast, and the only light came from Konrad's candle, which seemed to shrink from the darkness rather than cut through it.
But it was what lay on the table that made Konrad stop.
A sword. Long and straight, its blade black with tarnish, its hilt wrapped in leather that had rotted away in places to reveal the wood beneath. It lay on the table as if it had been placed there moments before and abandoned, a thing of purpose that had been left to wait.
Beside the sword was a box.
It was small, no larger than a prayer book, and it was made of yew wood, dark and close-grained. The lid was carved with a design that Konrad recognised—a wolf's head, its jaws open, its teeth bared.
The same design as the seal on the scroll Hedwig had given him.
His father's seal.
Konrad reached for the box, his fingers brushing the carved wolf's head. The lid lifted easily, too easily, as if it had been opened many times before.
Inside was a letter.
The parchment was yellowed with age, the ink faded to a brown that was almost illegible in the candlelight. But the hand was clear enough—a man's hand, firm and angular, the hand of someone who had written many letters and expected them to be read.
Konrad unfolded it. The words were in Latin, the language of clerks and kings, and they were dated: *Anno Domini 1268, mense Octobris*.
October 1268.
The month his father had died.
He read.
*To my son, Konrad von Eppenstein, if he should live to read these words.*
*I write this in the knowledge that I will not see the spring. The king—the man who calls himself king—has set his course, and I am the stone in his path. He does not know that I know. He does not know that I have written this account and placed it where he will never find it.*
*But you will find it, Konrad. You, who carry my blood and my name and my sin. You, who will one day understand why I did what I did.*
*Rudolf of Habsburg is not the true heir. The charter that names him is a forgery, and I have the proof. But I have also seen what the truth would do—what it would cost—and I have chosen to carry my silence to the grave rather than loose that serpent upon the world.*
*Do not mistake my silence for cowardice, my son. I am not afraid to die. I am afraid of what will happen after I am gone, when you are left to choose between the truth and the family that has raised you.*
*The river remembers, Konrad. And so must you.*
*Be careful who you trust. Be careful who you love. And if you ever find yourself standing at the edge of the water, remember that the river takes what it takes—but it also gives.*
*Your father,* *Hermann von Eppenstein*
Konrad read the letter twice. Then a third time, his eyes tracing the words as if he could find some meaning between them, some hidden message that would tell him what to do next.
The river remembers.
Hedwig had said the same words. His father had written them. And now Konrad stood in a sealed tower room in Prague, holding a letter that named his uncle a forger and his father a martyr, and the weight of it pressed down on him like the stones of the castle itself.
He folded the letter carefully and tucked it into his tunic, beside the others.
Then he looked at the sword.
It was his father's, he knew. He had never seen it, but he knew it the way a son knows his father's voice, even when he has never heard it. The blade was long and straight, a knight's weapon, and it was still sharp despite the years of neglect.
Konrad reached out and touched the hilt.
The leather crumbled beneath his fingers, and the wood beneath was smooth and warm, as if it had been held only moments before.
He lifted the sword from the table. It was heavy, heavier than it looked, and it balanced in his hand with a grace that spoke of a master smith's craft. He had held many swords in his life, but none had felt like this—like an extension of his own arm, like a thing that had been waiting for him to claim it.
The bells of St. Vitus began to toll.
Konrad started. The sound was close, louder than he had expected, and it reverberated through the tower like a hammer on an anvil. He had been in the room longer than he had realised. The guard would be changing. Eliska's warning echoed in his mind: *You have until the bells of St. Vitus to do what must be done.*
He did not know what must be done. But he knew he could not leave the sword.
He wrapped it in the remains of a tapestry, a faded cloth that bore the fading image of a lion rampant, and he tucked it under his arm. Then he closed the box, replaced it on the table, and blew out his candle.
The darkness swallowed him whole.
He found his way to the door by touch, his fingers tracing the iron bands, and he stepped out into the stairwell just as the bells fell silent.
The corridor below was empty. The guard had not yet come.
Konrad moved quickly, his footsteps silent on the worn stones, the sword heavy beneath his arm. He did not know where he was going, only that he could not stay here, could not be found with his father's blade and his father's letter and his father's death burning in his chest.
He reached the garden just as the first flakes of snow began to fall.
And there, standing in the shadow of the wall, waiting for him with a lantern in her hand, was Margarethe.
