4. Aconite Traces

The letter lay on Lydia Frost's nightstand like a dead moth, its six words burning through the paper as if written in acid rather than ink. She had read it twenty times since dawn, each reading yielding the same result: a cold knot in her stomach that tightened until she could barely breathe.

"Leave now, or suffer his fate."

The handwriting was unfamiliar—elegant, almost ornamental, the letters formed with a precision that suggested either a refined education or a deliberate attempt to disguise a more natural hand. The paper was cream-colored vellum of the sort sold at the stationer's shop on Harbinger Street, the sort anyone might purchase. The envelope bore no return address, only Lydia's name written in the same careful script.

She should have taken it to Detective Aldridge immediately. That was what an innocent woman would do. But Lydia had learned, in her twenty-eight years of navigating a world that had never quite made space for her, that innocence was not always a sufficient shield. Sometimes it was better to disappear before the accusations began, before the machinery of suspicion ground her into dust.

She folded the letter and tucked it into the inner pocket of her coat. Then she resumed packing, her movements quick and efficient, a skill honed by years of breaking down sled camps in the predawn dark.

The room at the Frostfire Lodge was small but comfortable, with a window that overlooked the frozen lake and the skeletal remains of the ice sculptures. Lydia had been staying here since the carnival began, grateful for the warmth and the hot water and the proximity to the dog yards where her team waited in their insulated kennels. She had planned to race in the championship the day after tomorrow. She had trained all year for it, scraping together sponsorship money, borrowing equipment, sleeping in her truck on the long drives between competitions. The Frostfire was supposed to be her moment—the race that would finally earn her a place among New Albion's elite mushers, the race that would prove she was more than just a novelty, a woman in a man's sport, a curiosity to be tolerated rather than respected.

Victor had believed in her. Or at least, he had said he did. She had been foolish enough to believe him.

She was zipping her duffel bag when someone knocked on the door. Three sharp raps, official and impatient.

Lydia froze. Her first instinct was to pretend she was not there. But the lamp was lit, and her silhouette was visible through the curtain, and whoever was knocking had probably already seen her.

"Miss Frost? This is Detective Aldridge. May I have a word?"

Lydia closed her eyes. Then she opened them, squared her shoulders, and walked to the door.

Detective Maya Aldridge looked different in the daylight—less severe, but no less watchful. She wore a heavy wool coat over her uniform and a scarf knitted in the bright geometric patterns of the Kaskapa people, a detail that Lydia noted with surprise. The Mounted Police were not known for embracing indigenous culture, and the scarf suggested either genuine appreciation or a calculated attempt to signal approachability.

"May I come in?" Maya asked, her eyes already scanning the room behind Lydia, noting the duffel bag on the bed, the empty drawers, the absence of personal belongings.

"I was just about to leave," Lydia said. "The race has been postponed, and I thought I'd take my dogs back to my training grounds near Glenmorrie. The snow is better there."

"The race hasn't been postponed. It's still scheduled for the day after tomorrow." Maya stepped inside without waiting for an invitation. "But you wouldn't know that, because the carnival committee only made the announcement an hour ago. So why don't you tell me why you're really leaving?"

Lydia felt the trap close around her. She had never been a good liar. It was one of the reasons Victor had liked her, she suspected—her transparency, her inability to dissemble, her guilelessness in a world full of guile. He had found it refreshing. She had found it a liability.

"I received a letter," she said finally. "This morning. It was slipped under my door before dawn."

She withdrew the envelope from her coat and handed it to the detective. Maya read the six words, her expression unchanging.

"'Leave now, or suffer his fate.' His fate being Victor Marwood's."

"I assume so."

"And you didn't think to bring this to me immediately? To the police?"

Lydia sat down on the edge of the bed, suddenly exhausted. "Detective, I'm a woman who was sleeping with a married man. A powerful married man. A man who has now been murdered. How do you think that looks? How do you think it will look when the newspapers get hold of it? I'll be tried in the court of public opinion before you ever find the real killer. And in this country, public opinion is the only verdict that matters."

Maya was silent for a moment. Then she sat down in the chair by the window, her posture relaxing slightly.

"You're not wrong," she said. "But running away will only make you look guiltier. If you're innocent—if you truly had nothing to do with Victor Marwood's death—then your best chance is to stay and help me find out who killed him."

"How can I help? I've already told you everything I know."

"Have you?" Maya leaned forward. "You told me about the affair. You told me about Victor's promises. But you didn't tell me about the letter he wrote you last week. The one where he said he was planning to leave his wife. The one where he mentioned a specific date."

Lydia's blood went cold. "How do you know about that?"

"I searched Victor's study yesterday evening, with the widow's permission. I found copies of his correspondence. He kept carbon copies of everything—letters, contracts, personal notes. It seems he was a meticulous record-keeper." Maya paused. "The letter to you was dated the day before he died. He said he planned to announce the separation at the carnival. He said he had already told Isobel."

"That's impossible. Victor never told Isobel anything he didn't have to. He was terrified of her."

The words were out before Lydia could stop them. Maya's eyes sharpened.

"Terrified of her? Why?"

Lydia hesitated. She had not intended to reveal this—it felt like a betrayal, even now, even after everything. But the detective was watching her with those patient, assessing eyes, and the letter was still burning a hole in her pocket, and she was so very tired of carrying secrets that were not hers to keep.

"Victor said things about his wife. Not often—he didn't like to talk about her. But sometimes, when he'd had too much to drink, he would get this look in his eyes. He said Isobel was not what she appeared to be. He said there was something wrong with her, something cold. He said she collected things. Knowledge. Information. He said she knew things about people that she had no business knowing, and that she used that knowledge like a weapon."

"Did he give you any specifics?"

"Once. He told me about a business rival named Carrington. Malcolm Carrington. He was trying to buy up timber rights in the northern territories, competing directly with the Marwood company. Victor was worried about it for months, and then suddenly Carrington withdrew his bid and left the country. Victor said Isobel had 'taken care of it.' When I asked what he meant, he said she had found out something about Carrington—something he would do anything to keep hidden—and she had made sure he knew she knew. Victor said it was like watching a spider wrap a fly."

Maya made a note in her small notebook. "Malcolm Carrington. I'll look into it. What else?"

"Nothing else. Victor clammed up after that. It was the only time I ever saw him afraid of anything." Lydia wrapped her arms around herself. "I didn't believe him, not really. I thought he was exaggerating. Isobel seemed so... gentle. So quiet. When I met her at the carnival functions, she was always polite, always gracious. She never gave any indication that she knew about Victor and me. But now, after the letter, after the way she looked at me at the wake—" She stopped, unable to finish.

"The wreath," Maya said. "The dried flowers in her hair."

"Monkshood. The same plant that killed Victor. She was wearing it like a crown."

Maya closed her notebook and stood. "Miss Frost, I strongly advise you not to leave Tamarack Pass. If you're in danger, the police can offer protection. If you're a suspect, leaving will only confirm my suspicions. Either way, your best course of action is to stay."

"And if the person who killed Victor decides to come after me next?"

Maya walked to the door, her hand resting on the frame. "Then I would suggest you be very careful about what you eat and drink. And I would suggest you keep that letter in a safe place. It may turn out to be the most important piece of evidence we have."

She left, her footsteps fading down the corridor. Lydia sat motionless on the bed, staring at the half-packed duffel bag, the empty drawers, the window that looked out onto the frozen lake.

She decided to stay. Not because she trusted the police, and not because she believed in her own innocence as a shield. She stayed because she remembered the look in Isobel Marwood's eyes at the wake, and she understood, with a clarity that felt almost like relief, that running would not save her. The widow's reach was longer than any distance she could travel, and her patience was longer still.

If she was going to die, she would die on her own terms. Not in some anonymous motel room on the road to Glenmorrie, but here, in the shadow of the Frostfire Carnival, where the ice sculptures glittered like frozen ghosts and the snow fell soft and silent, covering everything, burying everything, until nothing remained but the cold.

At the constabulary, James Wren was learning that the law was a blunter instrument than he had been taught in law school. He had spent the morning filing motions and drafting briefs, building the case for Calum Bishop's civil suit against Trooper Novak and the Mounted Police. The retaliatory arrest claim was strong—stronger than he had initially realized—but the judge was skeptical, and the Crown's lawyers were already maneuvering to have the case dismissed on the grounds that probable cause for the disorderly conduct charge insulated Novak from liability.

The probable cause argument was a poison pill. If the court accepted it, Calum's case would be dead before it ever reached trial, and the precedent would make it nearly impossible for any citizen of New Albion to challenge a retaliatory arrest. The police would be free to silence dissent with the cudgel of disorderly conduct, and no one would be able to stop them.

But James had found a crack in the armor. A narrow exception, buried in the footnotes of a twenty-year-old appellate decision from Port Providence. The ruling in Hyland v. Royal New Albion Constabulary had established that probable cause was not an absolute shield if the plaintiff could demonstrate that similarly situated individuals who were not engaged in protected speech had been treated differently. In other words, if Calum Bishop was the only person ever arrested for loud speech at the Frostfire Carnival, while dozens of other revelers had been equally loud and equally drunk and had faced no consequences whatsoever, then the probable cause defense might fail.

James had spent two days gathering evidence for this exception. He had interviewed carnival staff, vendors, and attendees. He had collected sworn affidavits from seven witnesses who had seen other intoxicated individuals behaving boisterously at the ice bar on the night of Calum's arrest, none of whom had been detained. He had even obtained a copy of the constabulary's arrest log for the past three years, which showed a pattern that was difficult to explain away: Calum Bishop was the first person in the history of the Frostfire Carnival to be arrested for disorderly conduct at the ice bar, despite the fact that the ice bar had been serving whiskey to loud, cold, and argumentative patrons for nearly a decade.

It was a slender thread on which to hang a case, but it was the only thread James had. He was determined to make it hold.

Detective Aldridge found him in the constabulary's small law library, surrounded by law reports and legal digests, his eyes red from lack of sleep.

"Mr. Wren. I've reviewed the documents you brought me. The loan from Marwood to Novak." She sat down across from him, her expression unreadable. "It's significant. But it's not proof of conspiracy. Novak could argue that the loan was a personal matter, unrelated to his duties as a trooper."

"Of course he could. But coupled with the timing of Calum's arrest—the same night Marwood was murdered—it creates a pattern. A pattern that a reasonable person might find suspicious." James pushed a document across the table. "I've also found this. A complaint filed two years ago by a man named Peter Draycott, who claimed Novak planted evidence during a search of his cabin. The complaint was dismissed, but the investigating officer noted 'irregularities' in Novak's report. That officer was subsequently transferred to a remote post in the Northern Territories."

Maya scanned the document, her frown deepening. "You've been busy."

"I've been thorough. There's a difference." James leaned back in his chair. "Detective, I think we're investigating two branches of the same tree. You're looking at a murder. I'm looking at a retaliatory arrest. But the roots—the roots are the same. Corruption. Abuse of power. A system that protects its own."

"You think Novak killed Marwood?"

"No. I don't think Novak is smart enough to have planned a poisoning. But I think he knows something. I think he was in Marwood's pocket, and I think he arrested Calum because someone told him to." James paused. "Someone who didn't want a witness talking about what he'd seen at the boathouse."

Maya was silent for a long moment. When she spoke, her voice was low and careful.

"The widow has an alibi for the time of the poisoning. She was in her sleigh, surrounded by dozens of people. No one saw her near Victor's wine glass. The forensic evidence is inconclusive. And she's been cooperating fully with the investigation—she volunteered access to her greenhouse, her husband's papers, everything. If she's the killer, she's either the most brazen woman I've ever encountered, or she's so confident in her own cleverness that she doesn't believe she can be caught."

"Which do you think it is?"

Maya met his eyes. "I think I need more evidence before I can answer that question. Which is why I'm going to Port Providence tomorrow. I want to look into this Malcolm Carrington business. And I want to talk to the solicitors who handled Marwood's estate planning. If Victor was planning to leave his wife, there might be a financial motive buried in the paperwork."

"And Novak?"

"Novak is under suspension pending an internal investigation. The Chief Constable wasn't happy about it, but the documents you provided made it impossible to ignore. He's been ordered to remain in Tamarack Pass until further notice." Maya stood. "Keep building your case, Mr. Wren. And keep me informed if you find anything else. It seems we're allies, whether we intended to be or not."

She left, and James returned to his books, the words blurring before his tired eyes. But beneath the exhaustion, he felt something he had not felt since leaving Port Providence: hope. Small and fragile, like the first green shoot pushing through frozen soil, but unmistakably alive.

At Winter's Rest, Isobel Marwood was writing in her diary. The greenhouse was warm and still, the monkshood nodding on their tall stems, the scent of earth and chlorophyll thick in the air. She wrote about the detective's visit, about the solicitor's investigation, about the girl Lydia Frost and the letter that had been slipped beneath her door.

She wrote about the envy that had driven her to this point—the envy that still burned, cold and steady, in the hollow of her chest. She had thought, once, that Victor's death would quench it. She had imagined the satisfaction of watching him fall, the release of tension, the peace that would follow. But the envy had not disappeared. It had only shifted its target.

Now it was Lydia she envied. Lydia, with her strong body and her easy laugh and her dogs that loved her without condition. Lydia, who had taken what belonged to Isobel and had not even had the grace to feel guilty about it. Lydia, who had been promised a future that Isobel had never been offered—a future of partnership and respect, not ownership and contempt.

The letter had been a warning, nothing more. Isobel was not ready to kill again. She was still savoring the first death, still luxuriating in the freedom it had brought her. But Lydia needed to understand that she was not safe, that no one was safe, that the world Isobel Marwood inhabited was a world of consequences, and the bill for betrayal was always due.

She closed the diary and locked the drawer and stood in the doorway of the greenhouse, looking out at the frozen estate. The snow had stopped, and the sky was clearing, and the first stars were beginning to appear in the violet dusk. It was beautiful, this place, in its cold and unforgiving way. Victor had built it to be a monument to his own greatness. She would remake it into something else—something that belonged only to her.

In the village, the lights of the Frostfire Carnival flickered against the darkening sky. The ice bar was still serving whiskey. The sled dogs were still barking in their kennels. The carousel was still turning, its painted horses frozen in mid-gallop, their glass eyes staring at nothing.

And somewhere in the mountains, the monkshood continued to bloom beneath the snow, patient and lethal, waiting for the spring that would release its poison once more into the world.
