9. Julian's Last Breath

The green light on Dmitri Volkov's transmitter pulsed like a heartbeat, steady and silent, and Caspar felt the weight of three years lift from his shoulders. For the first time since returning to Blackthorn Manor, he was not the hunted. He was not the victim. He was the one who held the advantage, and Vivian did not know it yet.

"How long will the jammer work?" Eleanor asked, her eyes fixed on the small device in Caspar's hand.

"Long enough. Volkov built it to last. He said it could run for twelve hours before the battery drained." Caspar slipped the transmitter back into his pocket. "We won't need twelve hours. The roads will be clear by noon. We only need to keep Vivian contained until then."

"Contained how? She's not going to sit quietly in her room while we wait for the police. She'll try something. She always tries something."

"Then we give her something to focus on. Something that keeps her occupied while we prepare." Caspar walked to the study door and opened it a crack, listening. The corridor was silent. "Where is the service tunnel entrance? The one she mentioned?"

"In the cellar. Behind the wine racks. There's a false wall that opens onto a stairway. It leads to the old stables, about half a mile from the house."

"Can it be sealed from the inside?"

Eleanor thought for a moment. "There's a heavy iron door at the bottom of the stairs. It locks with a key that's kept on a hook in the kitchen. Why?"

"Because if Vivian thinks her remote still works, she'll try to use the tunnel to escape before she triggers the explosions. We need to make sure that when she runs, she runs into a dead end."

"You want to trap her in the tunnel?"

"I want to remove her escape route. Without the tunnel, she's stuck in the house with us. And without the remote working, she has no leverage." Caspar's voice was cold and precise. "She's spent fifteen years believing she was the smartest person in any room. It's time to show her otherwise."

They moved through the manor like ghosts, silent and purposeful. Eleanor retrieved the iron key from its hook in the kitchen while Caspar checked the windows and doors, making sure that no one had entered or left since Vivian's departure to Julian's room. The snow was still melting outside, and the sound of dripping water filled the house like a whispered countdown.

The cellar was cold and dark, the stone walls weeping moisture, the air thick with the smell of damp earth and old wine. The wine racks stretched from floor to ceiling, hundreds of bottles covered in dust and cobwebs, a collection that Ignatius had curated over decades. Behind the farthest rack, exactly where Eleanor had described, was a section of wall that looked solid but swung inward at the touch of a hidden latch.

The stairway beyond was narrow and steep, carved from the bedrock beneath the manor. Caspar led the way, his flashlight beam cutting through the darkness. At the bottom, fifty steps down, they found the iron door.

It was ancient and heavy, its hinges rusted but still solid. Caspar inserted the key and turned it. The lock engaged with a satisfying clunk.

"Even if Vivian reaches this door, she won't be able to open it," he said. "And the walls are solid rock. She won't be digging her way out."

"What if she has another key?"

"The only key was in the kitchen. I have it now." He pocketed the key and turned back toward the stairs. "Let's go. We still need to deal with Julian."

Julian's room was at the end of the east corridor, the door slightly ajar. Caspar pushed it open and stepped inside. The curtains were drawn, and the room was dim, the only light coming from a small lamp on the nightstand. Julian lay on the bed, exactly where they had left him, his breathing shallow but steady, his face still gray but no longer blue.

And Vivian was sitting beside him.

She looked up when Caspar entered, her expression calm and untroubled. "I was wondering when you'd come. How is our dear brother doing?"

"He's alive," Caspar said. "No thanks to you."

"On the contrary. If I wanted him dead, he would be dead. The digitalis dose in his wine was calculated to incapacitate, not kill. Olivia was the one who tampered with it. She was always too eager, too impatient. She didn't understand that the art of poison is in the timing, not the body count."

"Is that what you tell yourself? That you're an artist, not a murderer?"

Vivian smiled. "I'm a scientist. Like Father. We both understood that knowledge requires sacrifice. The experiments we conducted on this family have advanced the understanding of toxicology by decades. The papers I'll publish — under a pseudonym, of course — will save lives. Real lives. Not just the lives of a few spoiled heirs."

"You're justifying murder with hypothetical futures."

"I'm acknowledging that progress has a price. Father taught me that. The first lesson he ever gave me was about the Kalidorian pufferfish. Did you know that its toxin is a thousand times more potent than cyanide? And yet, in the right dose, it can be used to treat chronic pain. The difference between medicine and poison is quantity. The difference between science and murder is intent." She stood and walked toward the window. "My intent was never to kill. It was to understand. Olivia forgot that. She let her hatred of this family override her commitment to the work. That's why she had to be removed."

"Removed," Caspar repeated. "Not killed. Removed. You can't even say the word."

"I can say it. Olivia is dead. I killed her. I switched the vials months ago because I knew, eventually, she would try to use the aconitine against someone. I assumed it would be you or Eleanor. I didn't expect her to drink it herself." Vivian turned back to face him. "But I'm not sorry she's dead. She was a liability. She was going to destroy everything I've built."

"Everything you've built," Caspar said. "A house full of corpses. A family destroyed. A legacy of poison and pain. That's what you've built."

"That's what Father built. I just inherited it."

Eleanor appeared in the doorway behind Caspar. She was holding something — a small leather case that Caspar recognized as Julian's medical kit. "Julian's pulse is getting weaker," she said. "We need to do something."

Vivian raised an eyebrow. "What do you suggest? We can't exactly call an ambulance."

"We can give him atropine. It counteracts the digitalis."

"I know what atropine does. I also know that the dose required to counteract digitalis toxicity is extremely precise. Too little and it does nothing. Too much and it causes cardiac arrest." Vivian walked to the bedside and looked down at Julian's unconscious form. "I could calculate the correct dose. I have his weight, his medical history, the approximate amount of digitalis he ingested. But why would I help him?"

"Because if he dies, your story falls apart," Caspar said. "You told us the plan. Olivia was supposed to be the unstable one. She poisoned Julian. She confessed and committed suicide. But if Julian dies, the police will investigate more thoroughly. They'll find evidence you haven't covered up. They'll find the truth."

Vivian considered this. "You make a valid point. Very well. I'll help him. But only because it serves my interests."

She took the medical kit from Eleanor and began to prepare a syringe. Her movements were precise and practiced, the movements of someone who had done this many times before. Caspar watched her hands, the steady fingers measuring the clear liquid, the calm expression on her face as she worked.

She was helping them. She was saving Julian's life. And yet Caspar felt no gratitude, no relief. Only a cold, certain dread.

Because Vivian never did anything that did not serve her interests. And if she was helping Julian, it meant she had a plan that required Julian to be alive.

"What are you really doing?" he asked.

Vivian did not look up from the syringe. "I'm administering atropine. As requested."

"That's not what I mean. You don't do anything without a reason. What do you need Julian alive for?"

She paused, the syringe hovering above Julian's arm. Then she smiled. "You're very perceptive. Father always said you were the smart one. Julian was the ambitious one, Olivia was the desperate one, and you were the smart one. He was almost sad when I convinced him to send you away."

"Answer the question."

"Julian knows something. Something I need. Before Father died, he told Julian the location of a document. A document that could be... inconvenient for me if it were ever found." She inserted the needle into Julian's vein and pressed the plunger. "I need Julian to wake up long enough to tell me where it is. After that, he's no longer useful."

Caspar felt his blood run cold. "The codicil. You're looking for the codicil."

Vivian's eyes flickered. "So you do know about it. I wondered if Father had told you."

"You burned it. Eleanor saw you burn it the night you killed Father."

"I burned one copy. But Father was paranoid. He kept backups of everything. I found two of them in the days after his death. But there's a third. A third copy of the codicil, hidden somewhere I haven't been able to find. Julian knows where it is. Father told him on his deathbed, as a final act of spite against me." She withdrew the needle and pressed a cotton ball to Julian's arm. "I've been searching for it for months. I tore this house apart. I searched every room, every safe, every hiding place I could think of. But Father was clever. He hid it somewhere I would never think to look."

"The hidden compartment in the safe," Caspar said. "Behind the false back."

Vivian stared at him. "What?"

"I found it this morning. There was a letter inside. Father's confession. He knew what you were. He was going to change his will. He was going to disinherit you and give everything to me."

For the first time since Caspar had returned to Blackthorn Manor, Vivian's composure cracked. Her face went pale, and something that might have been fear flickered in her dark eyes. "You're lying."

"I'm not. The letter is hidden somewhere you'll never find it. And when the police arrive, they'll read it. They'll know everything. The experiments. The poisonings. The murders. All of it."

Vivian was silent for a long moment. Then she laughed — a cold, bitter sound that echoed off the walls of Julian's bedroom. "You think a letter matters? You think a dead man's words will bring me down? I've spent fifteen years preparing for this. I have contingencies for my contingencies. Do you really think I don't have a plan for this?"

She reached into her jacket and withdrew the remote control. Her thumb hovered over the red button.

"You told me about the letter because you thought it would break me. But all you've done is confirm that I was right to prepare for the worst." She held up the remote. "If the police come to this house, they'll find nothing but rubble and corpses. I'll be long gone, halfway to the border with a new identity and enough money to disappear forever."

"Press it," Caspar said.

Vivian's thumb hesitated. "What?"

"Press the button. Blow up the house. Kill us all." Caspar stepped toward her, his winter-sea eyes locked on hers. "I know you won't. Because if you do, you'll never find the third copy of the codicil. You'll spend the rest of your life wondering when it will surface, when the evidence of your crimes will come to light, when the authorities will finally catch up with you. You can't destroy the evidence if you don't know where it is."

"You know where it is."

"Do I? Maybe I'm bluffing. Maybe the letter was the only copy, and you've already lost. Or maybe there's another copy, hidden somewhere even I don't know about, waiting to be found by someone else." Caspar smiled, and there was nothing warm in it. "That's the thing about paranoia, Vivian. It's a prison you build for yourself. And you've been living in it for fifteen years."

Vivian's face twisted with fury. For a moment, Caspar thought she might press the button anyway, might choose destruction over uncertainty, might burn everything down rather than admit defeat. But then her expression smoothed over, the mask sliding back into place, and she lowered the remote.

"You're bluffing," she said. "But I can't take that risk. Not yet."

"Then we're at an impasse."

"It seems we are." She slipped the remote back into her jacket. "But this isn't over. The roads may be clearing, but the police aren't here yet. And a lot can happen in a few hours."

She walked past Caspar and out of the room, her heels clicking on the hardwood floor. The sound faded down the corridor, and then the house was silent again.

Eleanor let out a breath she had been holding. "That was a gamble."

"It worked."

"For now. But she's right — a lot can happen in a few hours. What do we do?"

Caspar looked at Julian, still unconscious on the bed, his breathing slowly improving as the atropine took effect. "We wake him up. Vivian said Julian knows where the third copy of the codicil is hidden. If we can find it before she does, we have leverage. Real leverage."

"But the codicil you found in the safe — that was the letter. There is no third copy."

"I know. But Vivian doesn't. And Julian might know something else. Something Father told him that could help us." Caspar knelt beside the bed and pressed his fingers to Julian's throat. His pulse was stronger now, more regular. "Julian. Can you hear me?"

Julian's eyelids fluttered. His lips moved, but no sound came out.

"Julian. It's Caspar. You're safe. You're in your room. But I need you to wake up. I need you to tell me what Father told you before he died."

Julian's eyes opened. They were unfocused, clouded with pain and confusion, but they were open. He looked at Caspar as if he were seeing a ghost.

"Caspar," he whispered. "I'm sorry. I'm so sorry."

"You can apologize later. Right now, I need you to think. Father told you something before he died. Something about a document. A hiding place. Do you remember?"

Julian's brow furrowed. He was struggling to concentrate, fighting through the fog of poison and antidote. "He said... he said the truth was in the greenhouse. Not in the safe. Not in the study. The greenhouse. He said... he said I would know where to look."

"The greenhouse," Caspar repeated. "What part of the greenhouse?"

But Julian's eyes had closed again, and his breathing had returned to the slow rhythm of unconsciousness. The effort of speaking had exhausted him.

Eleanor looked at Caspar. "The greenhouse is huge. It could take hours to search."

"Then we'd better start now."

They left Julian's room and hurried through the manor toward the passage that led to the greenhouse. Caspar's mind was racing. The greenhouse. His father had hidden something in the greenhouse. But where? The workbench? The planters? The cabinets where Ignatius had kept his specimens?

And then he remembered. The day before the confrontation in Vivian's room, he had found his father's notebooks on the workbench. But he had not searched the rest of the greenhouse. He had not looked in the place where his father had spent the most time — the small office at the back of the glass structure, where Ignatius had kept his records and his reference books and the personal effects that no one else was allowed to touch.

The office door was locked, but Eleanor had a ring of keys that she had taken from the kitchen. The third key she tried fit the lock, and the door swung open with a creak of rusted hinges.

The office was small and cramped, lined with shelves that sagged under the weight of books and papers. A desk sat against the far wall, covered in notebooks and loose pages and the detritus of a lifetime of research. And on the wall above the desk, a single framed photograph.

It was a picture of Caspar as a child, perhaps ten years old, kneeling in the forest with a mushroom in his hand. His father was beside him, pointing at something in the undergrowth. They were both smiling.

Caspar had not remembered that photograph. He had not known it existed. And yet here it was, in his father's private office, the only personal item in a room dedicated entirely to work.

He lifted the photograph from its hook. Behind it, set into the wall, was a small safe — identical to the one in the study, but smaller, more discreet.

"The combination," Eleanor said. "Do you know it?"

Caspar thought for a moment. Then he entered his own birthday — the date he had been committed to St. Margaret's, the date that had been burned into his memory for three years.

The safe clicked open.

Inside was a document, folded and sealed with the Ashton family crest. Caspar broke the seal and unfolded it. It was the codicil — the real codicil, the one that Vivian had been searching for, the one that Ignatius had hidden where only his youngest son would think to look.

"To my children," the document began. "If you are reading this, then I am dead and the truth must finally be told. My daughter Vivian is a murderer. She has poisoned her siblings, manipulated this family, and corrupted the work that I dedicated my life to. I have evidence of her crimes, stored with my solicitor Marcus Weller. I hereby disinherit Vivian entirely and grant the controlling share of the Ashton estate to my son Caspar, who was wrongfully committed and whose innocence I acknowledge too late."

Caspar lowered the document. "We have it. We have everything we need."

"Then we can go to the police," Eleanor said. "We can end this."

But before Caspar could respond, a sound echoed through the greenhouse. A woman's scream. High and sharp and abruptly cut off.

They ran toward the sound, through the rows of dying plants and the shattered glass of the greenhouse, toward the main house. The door to the kitchen was open. The kitchen was empty.

And on the floor, beside the overturned breakfast table, lay a body.

It was Vivian.

She was on her back, her eyes open, her face frozen in an expression of shock. A syringe protruded from her neck, the plunger fully depressed. And beside her body, written in what looked like her own lipstick on the stone floor, was a single word.

"JULIAN."
