5. Lydia in the Frame

The ice track at the Frostfire Carnival stretched for twelve miles across the frozen surface of Lake Tamarack, a serpentine ribbon of packed snow and glazed corners that had been carved by a team of groomers working through the bitterest nights of January. At dawn on the morning of the championship race, the track was a thing of brutal beauty—smooth as polished bone, glittering under a sky the color of hammered pewter, the air so cold it felt like shards of glass in the lungs.

Lydia Frost arrived at the dog yard two hours before the starting gun. She had not slept. The letter was still in her coat pocket, its six words now worn soft from repeated handling. She had read it again at three in the morning, sitting cross-legged on her bed while the wind howled against the lodge's windows, and she had come to a decision.

She would race.

Not because she was brave—Lydia had never considered herself brave, only stubborn—but because the track was the one place where the world made sense. The dogs understood her there. The sled responded to her weight shifts, her whispered commands, the subtle language of pressure and release that she had spent a decade learning. On the track, she was not the mistress of a dead timber baron, not the recipient of anonymous threats, not a suspect in a murder investigation. She was simply a musher, and her only job was to run.

Her lead dog, a silver-grey husky named Boreas, whined softly as she approached the kennel. The other dogs stirred behind him—eight in total, a mix of Alaskan huskies and New Albion sled dogs, their breath pluming in the cold air. Lydia knelt beside Boreas and pressed her forehead against his, feeling the warmth of him, the steady rhythm of his heart.

"You ready, old man?" she whispered. "One last run?"

Boreas licked her cheek. It was answer enough.

The crowd at the starting line was smaller than in previous years—Victor Marwood's death had cast a pall over the festivities, and many of the carnival's more genteel attendees had already departed for the safety of Port Providence. But the hardcore racing fans remained, bundled in furs and wool, stamping their feet against the cold and drinking hot cider from tin cups. They were a different breed from the tourists, these fans. They knew the mushers by name, knew the bloodlines of the dogs, knew the treacherous corners of the track where a sled could flip and a team could tangle. They had come to see a race, and the race was what they would get.

Lydia lined up her team at the chute, her heart hammering against her ribs. She had drawn the seventh starting position, which meant she would have to overtake six other teams if she wanted to win. It was not impossible—she had done it before, at the Glenmorrie Winter Classic two years ago—but it would require a near-perfect run, and her dogs were edgy from too many days of confinement.

"Racers, prepare your teams!"

The announcer's voice echoed across the frozen lake. Lydia tightened her grip on the sled's handlebar, her eyes fixed on the back of the musher ahead of her, a burly man from the northern territories named Gunnar Eklund who had won the Frostfire three times and was widely expected to win again.

"Thirty seconds!"

Boreas was pulling at the traces, his body vibrating with anticipation. The other dogs followed his lead, a wave of canine energy that Lydia could feel through the sled like an electric current.

"Ten seconds!"

She took a deep breath, the cold air searing her lungs, and then the starting pistol cracked and the chute opened and they were flying.

The first three miles of the track were a straightaway along the western shore of the lake, and Lydia let the dogs run, holding them back just enough to conserve their strength for the climbs ahead. They passed one team, then another, Boreas setting a pace that was punishing but sustainable. The sled runners sang against the packed snow, a high keening note that was the soundtrack of Lydia's life, the music she heard in her dreams.

At the four-mile marker, the track veered into a series of sharp turns through a stand of ancient pines, their branches heavy with snow. Lydia shifted her weight, leaning into the curves, her body moving in concert with the sled. The dogs responded perfectly, Boreas leading them through the labyrinth with the instinct of a creature born to the ice.

They passed two more teams in the forest, and by the time they emerged onto the open lake again, they were in third place. Gunnar Eklund was still ahead of her, his bright red sled visible as a distant speck against the white expanse. Behind him, in second place, was a young musher from the coastal villages named Soren Lindqvist, a prodigy who had burst onto the racing circuit the previous winter and had been winning ever since.

Lydia urged her team forward, her voice low and urgent. The dogs responded, Boreas digging deep, the others following his lead. The gap between her and Lindqvist began to narrow.

And then, on a long sweeping curve near the eight-mile marker, everything went wrong.

It happened without warning. One moment Boreas was running true, his gait fluid and powerful; the next, he stumbled, his front legs buckling, his body twisting sideways. The traces tangled. The sled lurched violently. Lydia threw her weight against the handlebar, trying to correct, but it was too late. The team was in chaos, dogs yelping and snapping, the sled skidding toward a snowbank at the edge of the track.

Lydia hit the snow hard, the impact driving the breath from her lungs. For a long moment, she lay still, the cold seeping through her coat, the sky a white blur above her. Then the training kicked in, and she was on her feet, checking the dogs, untangling the traces, her hands moving with practiced efficiency even as her mind screamed that something was wrong.

Boreas was the problem. He had collapsed in the traces, his breathing shallow, his gums pale. Lydia knelt beside him, running her hands over his body, searching for injury. There was nothing visible—no cuts, no swelling, no sign of a collision. But the dog was clearly in distress, his eyes glassy, his muscles twitching.

"Boreas. Boreas, stay with me."

The other mushers had stopped now. Lindqvist had circled back, his young face creased with concern. Eklund had halted his team a hundred yards ahead and was walking back toward them, his stride heavy and deliberate.

"What happened?" Lindqvist asked, his voice high with alarm.

"I don't know. He just collapsed."

Eklund reached them, his weathered face unreadable. He knelt beside Boreas, his thick fingers probing the dog's abdomen, checking his reflexes. After a moment, he looked up at Lydia, and his expression was not one she had ever seen on him before.

"Has he eaten anything unusual this morning? Anything you didn't prepare yourself?"

Lydia felt the cold knot tighten in her stomach. "What are you saying?"

"I'm saying this dog has been poisoned." Eklund's voice was flat, matter-of-fact. "I've seen it before, in the territories. Aconite, most likely. Same thing that killed Victor Marwood."

The world tilted. Lydia gripped Boreas's fur, feeling the shallow rise and fall of his breathing, the tremors that ran through his body. Poisoned. Someone had poisoned her dog. Someone had tried to poison her.

"Get him to the veterinary tent," Eklund said. "There's a vet from Port Providence on site. She might be able to save him if you hurry."

Lydia did not remember the rest. She did not remember calling for the sled to be cleared, or loading Boreas onto the rescue sleigh, or the long, agonizing ride back to the carnival grounds. She remembered only the weight of the dog's head in her lap, the soft whimper of his breath, the words that repeated in her mind like a prayer: Stay with me, stay with me, stay with me.

The veterinary tent was pitched near the main lodge, a canvas structure lit by kerosene lamps and heated by a cast-iron stove. The vet, a brisk woman named Dr. Helena Vance, examined Boreas with the efficiency of someone who had spent too many years treating animals in the backcountry to be surprised by anything.

"It's aconite," she confirmed, her voice clipped. "The symptoms are textbook. Numbness, paralysis, respiratory distress. But the dose was low—lower than what killed Marwood. Either someone made a mistake, or someone wanted to send a message."

"A message?" Lydia's voice was hoarse. "To me?"

"Someone poisoned your lead dog the morning of the championship race. That's not a random act of cruelty. That's a statement." Dr. Vance looked up from the dog, her eyes sharp behind her spectacles. "I'd say someone wants you to know they can reach you. Anytime. Anywhere."

Lydia sat down on a bale of hay, her legs suddenly too weak to hold her. The letter was still in her pocket. The six words. The elegant handwriting. The veiled threat that had now become something far worse.

"Is he going to live?"

"He'll live. But he won't race again this season. Maybe not ever. The damage to his nervous system may be permanent." Dr. Vance paused. "I'm sorry. He's a beautiful animal."

Lydia closed her eyes. In the darkness behind her lids, she saw Isobel Marwood's face, calm and gracious, the wreath of dried flowers woven into her hair. She saw the widow's hands, pale and elegant, offering her a cup of mulled wine at the carnival reception two nights ago. She saw the small velvet pouch that Isobel had carried, the one she had tucked into her apron when she thought no one was looking.

"Thank you, Doctor. I need to make a call."

She walked to the lodge on legs that felt like ice, the cold seeping through her boots, the wind cutting through her coat. In the lobby, she found the telephone and asked to be connected to the constabulary.

"Detective Aldridge, please. It's urgent."

Maya Aldridge was in Port Providence, a hundred miles to the south, but the duty sergeant patched the call through to her hotel. When she came on the line, her voice was thick with sleep.

"Miss Frost? It's six in the morning."

"Someone poisoned my dog, Detective. My lead dog. With aconite. The same poison that killed Victor."

There was a long silence. Then Maya said, "Are you certain?"

"The vet confirmed it. She said the dose was low—too low to kill him outright. She said someone wanted to send a message."

Maya's voice sharpened, the sleep disappearing. "Where are you now?"

"At the lodge. The veterinary tent. I don't know what to do. I don't know where to go."

"Stay there. Stay in a public place, surrounded by people. Do not go back to your room alone. Do not eat or drink anything you haven't prepared yourself. I'm going to call the constabulary and have an officer stationed with you until I can get back."

"Maya." Lydia used the detective's first name without thinking. "It's her. It's Isobel Marwood. I know it is."

"We don't have proof. Not yet. But I'm working on it." Maya's voice softened. "I found something in Port Providence. Something about Malcolm Carrington, the business rival you mentioned. It's worse than we thought. I'll tell you everything when I return. But for now, you need to stay alive. Do you understand me? Stay alive, and stay visible."

The line went dead. Lydia stood in the lobby, the telephone receiver still in her hand, the murmur of early-rising guests flowing around her like water around a stone. She had never felt more alone in her life.

James Wren was in the law library when the news reached him. He had been there since five in the morning, preparing his brief for the retaliatory arrest hearing, which had been scheduled for the following week. The case had grown more complicated in the past few days, the threads of Calum's arrest weaving ever more tightly into the fabric of Victor Marwood's murder, and James was beginning to feel like a man trying to map a labyrinth while standing in the middle of it.

The constable who brought the news was a young man named Everett, one of the few officers at the Tamarack Pass detachment who seemed genuinely interested in justice rather than convenience. He found James hunched over a stack of law reports, his collar unbuttoned, his hair disheveled.

"Mr. Wren? There's been another poisoning. The sled racer, Lydia Frost. Someone tried to kill her dog. Used the same stuff that killed Marwood."

James looked up, his exhaustion momentarily forgotten. "Is she all right?"

"She's fine. The dog's alive, too, but just barely. Detective Aldridge has ordered a protective detail on her until she returns from Port Providence."

"Port Providence. What's she doing there?"

The constable hesitated. "I'm not supposed to say. But I think she found something. Something that connects the widow to another case. An old case."

James closed the law book and stood, his joints protesting. "I need to see Calum. And I need to see the widow. Not necessarily in that order."

But when he arrived at Winter's Rest an hour later, the house was empty. Not abandoned—the servants were still there, the fires still burning, the great granite halls still echoing with the silence of a mausoleum. But Isobel Marwood was gone.

"She left early this morning, sir," Mrs. Garrick said, her face pinched with disapproval. "She said she needed to collect specimens in the mountains. For her greenhouse. She took a sleigh and a driver and said she would return by nightfall."

"Where in the mountains?"

"She didn't say, sir. She never says. She just goes."

James stood in the great hall, the heat of the fire at his back, the cold of the house seeping into his bones. The widow was in the mountains, alone, collecting plants. It could be innocent—a harmless eccentricity, the hobby of a woman with too much time and too little company. Or it could be something else entirely.

He thought of the monkshood growing in her greenhouse, the dozens of plants with their purple hoods and their lethal roots. He thought of the seeds she had been gathering on the morning he first visited, the small velvet pouch, the careful precision of her hands. He thought of the poison that had killed Victor Marwood, and the poison that had nearly killed Boreas, and the letter that had been slipped beneath Lydia Frost's door.

And he wondered, for the first time, whether Isobel Marwood was not merely a murderer, but something far more dangerous: a woman who had discovered that destruction was her only form of agency, and who had decided to wield it without restraint.

In the mountains above Tamarack Pass, the snow was deep and the air was thin and the sky was the color of hammered silver. Isobel Marwood walked alone along a ridge that overlooked the frozen lake, her boots crunching in the crusted snow, her breath forming clouds that drifted away on the wind.

She was not collecting specimens. She was collecting herself.

The poisoning of the dog had been a mistake—not in execution, but in conception. She had meant it as a warning, a way to drive Lydia Frost away without resorting to the finality of murder. But the warning had backfired. It had drawn attention to the very thing she was trying to conceal. The detective was in Port Providence now, digging into the past, unearthing things that were meant to remain buried. The solicitor was building a case that threatened to expose the connections she had worked so carefully to hide.

She had underestimated them. She would not make that mistake again.

Ahead of her, the ridge dropped away into a valley where a frozen stream wound through a stand of ancient pines. Isobel stopped at the edge of the precipice and looked down, her hands buried in the pockets of her fur coat. In her right pocket, the velvet pouch of monkshood seeds. In her left, a small glass vial of refined aconitine, prepared in her greenhouse laboratory, concentrated to a potency that could stop a heart in minutes.

She had choices to make. Lydia Frost was one. The solicitor was another. The detective was a third. And then there was the trooper, Novak, who knew enough to be dangerous but not enough to protect himself. Each of them was a threat. Each of them needed to be neutralized.

But Isobel was patient. She had spent seven years married to a man she despised, seven years smiling and serving and pretending to be something she was not. She could wait a little longer. She could let them chase their shadows, build their cases, believe they were closing in on her. And when they were confident enough to make a mistake, she would be ready.

The sun broke through the clouds, turning the snow to diamonds. Isobel stood at the edge of the precipice, her face tilted to the light, and she smiled—a small, private smile that no one saw, the smile of a woman who had discovered that the greatest power was not the power to build, but the power to destroy.

In the valley below, a fox crossed the frozen stream, its red coat brilliant against the white. Isobel watched it until it disappeared into the trees. Then she turned and began the long walk back to the sleigh, her footprints the only mark on the pristine snow.

By the time she returned to Winter's Rest, the sun had set and the stars had emerged and the temperature had dropped to twenty below. She found James Wren waiting for her in the great hall, his face pale, his hands trembling slightly—not from fear, but from the cold that had seeped into him during the hours he had waited.

"Mrs. Marwood. I need to ask you some questions."

"Of course, Mr. Wren." She removed her gloves, one finger at a time. "But first, let me offer you some tea. You look frozen."

James hesitated. Then he said, "No, thank you. I'd prefer to get straight to the point."

"As you wish." Isobel settled into the chair by the fire, her expression serene. "What would you like to know?"

And James, looking at her in the firelight, realized with a chill that had nothing to do with the cold that he had no idea what to ask. She had anticipated everything. She was ready for everything. And whatever trap he thought he was setting for her, she had already set a dozen for him.
