The Arrest Upon the Blade

"There are two ways to be caught beside a corpse. One of them is innocence."

Thalessa did not move.

She stood with the scalpel still in her right hand, its edge a thin bright line in the lantern light, and the chest cavity of Ragnar Sterling laid open at her hip like a book. The cold of the ice house had gone into her bones. She could feel her own pulse in the tips of her fingers.

"Put the knife on the slab," said the voice behind her.

She set it down.

"Both hands on the edge of the table. Palms flat. Where I can see them."

She did that too.

Footsteps crossed the flagstones, slow and even, until they stopped about six feet behind her. She heard the faint creak of a leather coat, the damp breath of a man who had come through the cold. And she smelled him, clove and wet wool and gun oil, a scent that she would have known in the dark by now.

"Inspector Thorne," she said, without turning. "You told the Duke nobody would touch the body until morning."

"I did."

"It is morning, by the clock in the hall. Not yet four."

"That is not a defense."

"I did not suppose it was." She kept her eyes on the dead man's face. "You will have noticed that the body was washed before I arrived. The hand has been cleaned, and the nail drawn. I wished to know what else had been changed."

"You wished to know." Roderick's voice was quiet and flat. "In the small hours. With a bone saw, in a room that I locked, in a house where a man was murdered five hours ago."

"The study is locked. This room was not."

"Because I did not suppose that anyone would come to the ice house to cut open the dead."

"Then you underestimated the interests of the dead."

There was a short silence.

"Turn around," Roderick said.

She turned.

He stood at the foot of the stair with the silver revolver leveled at her breastbone, and his arm did not shake at all. He had thrown off his coat. His shirt was open at the throat and stuck to him with sweat, and the cold had put two spots of dull red on the hard planes of his cheekbones. In the dim, swaying light his eyes looked almost colorless. They moved over her slowly: the gloves, the apron of her ash-gray coat, the dark smear of fluid across her cuff, the open chest on the table beside her, the instruments laid out like an altar.

He took in all of it. His jaw tightened.

"A woman arrives at an isolated estate three days after her betrothed is poisoned," he said. "In the night, a guest at the same house is murdered with a poison of the same family. The woman is found alone with the body. Her instruments are out. Her hands are wet." He paused. "I should be very glad to be told what you would conclude, in my place."

"That I killed him."

"Yes."

"That I came here to avenge Thorne Valerius."

"It is the simplest reading."

"It is the simplest and the stupidest." Thalessa's voice was ice. "If I were a poisoner come for revenge, Inspector, I should not have spent the evening making speeches in the dining hall. I should not have told five frightened people the name of the toxin. And I should most certainly not have cut open my victim's chest by lantern-light, in a cellar with one door, to be found by the first man who happened to wake."

"Perhaps you are very clever."

"Perhaps I am. But a clever poisoner does not take her own samples."

He didn't lower the revolver. But the barrel dipped a fraction, as if of its own accord.

"Explain," he said.

She nodded at the glass plate on the cloth, still faintly steaming from the spirit lamp.

"I have taken the contents of the stomach and tested each in turn. The cabbage is clean. The bread is clean. The dried fruit is clean. The tea, which you suspected, I have not yet tested, but I did the jade strip on the saucer upstairs, in this house, and it showed no reaction." She looked at him. "The poison was in the wine."

"The wine."

"A Burgundy. Probably a single glass. Concentrated wisteria root, bound to a salt of mercury, which makes it soluble and, in wine, almost without taste. It acts in thirty to forty minutes. Ragnar Sterling swallowed it at the dinner table, with every one of us watching."

Roderick said nothing. The revolver did not move.

"Everyone drank from the same decanter," Thalessa went on. "The footman, Mr. Finch, filled the glasses himself. He has told me so. If the wine in the decanter were poisoned, you and I and the Duke would be lying on this slab beside him. We are not. Which means the poison was never in the decanter. It was in his glass, before the wine was poured."

"The footman."

"Mr. Finch says he does not set the glasses. Miss Haze does."

"The blind woman."

"She sets the table by touch, he says. She places everything. Every cup, every spoon." Thalessa's eyes did not leave his face. "I do not say it was she. A blind woman may carry out a murder as well as any other, I suppose, but I should think it rather difficult to coat the inside of a particular glass with a poison she cannot see, for a particular man she cannot see, at a table she cannot see. But I tell you where the poison was. You may do with it what you like."

Silence filled the stone room.

Somewhere in the walls the ice shifted with a faint groan, and a slow drip began from a corner of the vault.

"The petal," Roderick said at last.

"It was in his mouth." She picked up the glass slide with the forceps and held the flake of violet to the lantern. "A fragment, softened by saliva. When the head is thrown back as it was, a petal dropped from the ceiling would fall exactly there."

"The ceiling."

"There is an iron grille above the desk in the study. A ventilation rosette. I walked beneath it."

She watched him think. It was an interesting thing to watch. His face did not change, but she saw the lines at the corners of his eyes tighten and deepen, and she saw the slow turning of his mind behind them, like the wheels in a lock.

"And the knot?" he asked, quietly.

She blinked. "What knot?"

"You looked at the left wrist for a very long time, Scholar Ashwood. I have been watching you from the stair for ten minutes."

So he had been there longer than she thought. She felt the small cold flush of embarrassment and suppressed it.

"It is an anchor bend," she said. "The knot used to fasten a line to a ring. A man who has worked ships ties it without thinking. Few others would know it."

"A sailor."

"Or a sailor's sister," said Thalessa, "or a man who learned from one. I draw no conclusions."

"You have drawn several."

"I have drawn a good many. I have stated none of them as fact."

He regarded her for a long moment. Then, very slowly, he let out a breath, and with a quick economical movement uncocked the hammer and let the revolver fall to his side.

"You are not the poisoner," he said.

It was not a question, and it was not quite a verdict. It was the tone of a man annoyed with himself.

"I did not say so."

"No. You said very little, in the circumstances. You made me argue it for you." His mouth hardened. "I am not in the habit of being outmaneuvered by suspects."

"Then you have had a novel evening, Inspector."

Something flickered across his face, dry and unwilling, that might in another man have been amusement. It was gone before she could be certain.

"I should still prefer," he said, "that you had come to me first."

"I should still prefer that you had posted a guard."

"Touché."

"I do not play at fencing."

"I'm aware."

He stepped forward, holstering the revolver. "Tell me about the hour. If the poison was in the glass, when did he drink it?"

"At the first toast. Twenty past eight, near enough. Mr. Sterling left the table at nine, complaining of heat and a tightness in the chest. By then the poison had been in him for forty minutes and had begun to close his throat." She tapped the edge of the slab. "The man who nailed his hand to the desk did not do it while he lived. The wire was tied afterward, and so was the clockwork. Which means that someone entered that study, or was already inside it, after he died."

"The door was bolted from within."

"The door was bolted from within," she agreed. "The door is not the only way into a room, Inspector. It is merely the way a room wishes to be thought of."

"You sound like a woman with a theory."

"I sound like a woman with a petal, a knot and a wound that did not bleed. A theory is what you build when you are tired of being afraid."

He looked at her a moment longer than courtesy required. Then he said, in a lower voice, "The Duke had the body washed before I could stop him. He said it was decency. I thought it was fear."

"It may be both. Fear is very decent, at a certain hour."

The lantern light slid over his shoulders and the lines of his coat. The lantern light slid over his shoulders and the lines of his coat. He stopped beside the slab and looked down at the opened chest of the merchant, and for the first time she saw his face change. It was a small thing. A tightening of the nostrils. A slight shifting of the eyes.

"I have seen two hundred corpses," he said, "and I cannot get used to it. Isn't that absurd?"

"It is not absurd. It is the beginning of competence." Thalessa picked up a cloth and wiped the scalpel. "A man who grows used to this should be removed from the work."

"You're used to it."

"I am not used to it. I have learned to keep my hands warm."

She heard the words as she said them. They were Thorne's words, or nearly, spoken on a long gold afternoon in the toxicology laboratory. Your fingers were born to search for truth, but your heart must never turn to ice. She set down the scalpel and was suddenly conscious of how very tired she was.

Roderick looked at her face.

"Scholar Ashwood—"

He broke off.

His head had turned toward the stair.

She heard it a heartbeat after he did. Above them, faint and far away, the groan of a door. Then, closer, the soft, steady, deliberate fall of a man's footsteps on the spiral stone.

Roderick moved before she could speak.

He crossed the floor in two strides, seized the lantern from the head of the slab, and shut its shutter with his thumb, plunging the vault into darkness. His other hand closed on her wrist. She felt his grip, hard and warm through the glove, drawing her sideways, into the narrow gap between two great stacked blocks of lake ice and the rock wall.

"Silence," he breathed against her ear.

She was pressed against the wall of stone with his shoulder against hers, and the cold of the ice at her back, and the wet-wool warmth of his chest against her arm. She could feel the beating of his heart. Fast, hard, perfectly regular. She held her breath.

The footsteps reached the bottom of the stairs.

A thin yellow light spilled across the floor, the glow of a candle carried low. Whoever held it paused on the last step. A faint sound followed, a rustling, as of fabric being drawn aside.

"Poor fool," said a voice, in the dark.

It was a cold, dry, unhurried voice, faintly amused. Thalessa knew it at once.

Doctor Malthus Malakor.

She turned her head very slowly and looked past the edge of the ice.

The army surgeon stood beside the marble slab with a candle in one hand. In its light his spectacles were two small round discs of fire. He was in his shirt-sleeves, with his coat hung over his arm, and his long face had the look of a man who had been sitting awake in a chair for hours, waiting for a particular moment. He looked at the open chest, at the cloth, at the plate of residue, and the corners of his thin mouth turned downward.

"Someone has been busy," he said softly.

His eyes traveled slowly over the room, over the shadows between the ice blocks. For an instant they seemed to rest on the very place where Thalessa stood. She felt Roderick's hand tighten on her wrist.

Then the doctor looked away.

He set the candle on the slab. He bent over the body and, with a curious absence of haste, drew down the linen sheet from the dead man's waist to his knees. He turned the right thigh outward with both hands, as a man turns a joint of meat. And he held the candle to the pale flesh.

Thalessa could see it from where she stood.

A scar.

It ran along the outer side of the thigh, from the hip to just above the knee, a long, broad, puckered band, the color of old candle wax, wider at the center, and seamed with the white thread-lines of a surgeon's stitches. It was not a wound that she would have taken for an accident. It was far too regular, too deliberate, too clean.

Malthus laid two fingers along it. He moved them slowly down its length, in the manner of a man reading a line of print with his hand.

"Forgive me, Ragnar," he murmured.

He pulled the sheet back over the body. For a time he stood quite still, with the candle in his hand and his head bowed. Then he straightened, picked up the glass plate with the residue, and, with a swift, contemptuous flick of the wrist, dashed its contents into the floor drain.

Thalessa made a sound.

It was a tiny sound, hardly a breath. But Roderick's hand pressed warningly on her wrist, and the doctor's head began, slowly, to turn.

For three seconds that were longer than a year, nobody moved.

Then, far above them, the clock in the hall began to strike. It struck four. Its brazen voice rolled down the stairwell and flooded the vault. Malthus frowned, glanced upward, took his candle, and went back up the steps with the same unhurried tread.

The door groaned. The light vanished.

The darkness settled again, thick as wool.

They stayed where they were, listening, until the last echo of his steps had died away. Then Roderick released her wrist. She found that her fingers had gone numb.

"He took the evidence," Thalessa whispered. Her voice shook with a fury that surprised her. "The stomach contents. The residue. He tipped it down a drain."

"I saw."

"I have the slide. The petal fragment. I have the jade strip, and my notes."

"I know." Roderick's voice was very low. "You have also seen what he looked at."

"The scar."

"Yes."

"A thigh. A long excision, healed, years old." She drew a slow breath. "That is not a wound from a ship's debris. That was cut by someone who knew exactly where to cut. And Doctor Malthus knew precisely where to look."

Roderick relit the lantern. The light flared and steadied, and she saw his face, taut and gray, with something in it she had not seen before. It was not suspicion. It was closer to dread.

"Scholar Ashwood," he said. "I think we had better talk."
