Clara huddled in the panic room beneath the mansion, Marcus’s confession clutched against her chest as the sounds of violence raged above her. The reinforced walls muffled the worst of it, but she could still hear gunfire, shouting, and sounds that didn’t seem entirely human. Her nursing training told her to tend to the wounded, but Marcus’s final plea kept her frozen in place.
The recording device he’d given her contained hours of testimony, and she forced herself to listen while waiting for the violence to end. Marcus’s voice, sometimes strong and sometimes broken with pain, detailed not just his own suffering but the existence of other facilities, other victims. Names of politicians and business leaders who had funded the research. Bank account numbers. Shipping manifests for equipment.
It was enough to bring down an empire built on human suffering.
The sounds from upstairs gradually subsided, replaced by an eerie silence that was somehow worse than the chaos. Clara waited, counting her heartbeats, until she heard footsteps on the basement stairs. Slow, measured steps that could belong to either Marcus or his captors.
“Clara?” The voice was hoarse, barely recognizable, but unmistakably Marcus. “It’s over. You can come out.”
She emerged from the panic room to find Marcus slumped against the laboratory wall, his clothes torn and stained with blood. His skin had taken on an even more translucent quality, and she could see dark veins spreading like spider webs beneath the surface.
“Are you hurt?” she asked, rushing to his side despite his earlier warnings.
“Not hurt,” Marcus said with a bitter laugh. “Dying. The exertion accelerated the cellular breakdown. I can feel my organs starting to shut down.”
Clara knelt beside him, her nursing instincts taking over. His pulse was erratic, his breathing shallow, and his skin felt fever-hot to the touch. “We need to get you to a hospital—”
“No hospital can help me,” Marcus interrupted gently. “And we don’t have time anyway. Alexander escaped during the fighting. He’s going to disappear, probably leave the country. If we’re going to stop him, it has to be tonight.”
Clara looked around the basement, noting the bodies of Alexander’s soldiers scattered throughout the laboratory. She couldn’t tell how many there were, and part of her didn’t want to know what Marcus had been forced to become to defeat them.
“How?” she asked simply.
Marcus pulled a sat-phone from his jacket, its screen cracked but still functional. “I intercepted their communications during the fight. Alexander’s evacuating to a safe house, then taking a private jet out of the country. But first, he’s making one stop.”
He showed her a text message on the phone’s screen: “Package secured at lighthouse coordinates. Final extraction at dawn.”
“Package?” Clara asked, though she was afraid she already knew the answer.
“Dr. Crenshaw,” Marcus confirmed. “And probably samples of the enhancement serums. Alexander’s going to sell the research to the highest bidder and disappear with enough money to live like a king for the rest of his life.”
Clara felt a surge of determination that surprised her with its intensity. “Then we stop them.”
“Clara, listen to me.” Marcus struggled to sit up straighter, his enhanced hearing picking up sounds she couldn’t detect. “I have maybe hours before complete organ failure. What I’m going to ask you to do… it’s dangerous, and I can’t guarantee I’ll be able to protect you.”
“What do you need me to do?”
Marcus managed a weak smile. “I need you to be bait one more time.”
An hour later, Clara stood at the edge of the lighthouse parking lot, the confession and evidence tucked safely in her jacket. The lighthouse itself was an imposing structure, its beam cutting through the pre-dawn darkness in regular sweeps. She could see movement in the windows of the keeper’s house—shadows that suggested at least three people inside.
Marcus was positioned somewhere in the rocks below the lighthouse, though Clara couldn’t see him. The plan was simple in its audacity: Clara would approach openly, allowing herself to be captured. While Alexander and Dr. Crenshaw interrogated her, Marcus would infiltrate the building and eliminate any remaining guards.
It relied on Alexander’s arrogance, his assumption that Clara was still the grieving, passive victim he’d manipulated for months. It also relied on Marcus maintaining enough humanity to distinguish between enemies and innocents, despite the enhancements ravaging his system.
Clara walked toward the lighthouse, her hands visible and empty, playing the role of the frightened woman seeking answers. The front door opened before she reached it, and Alexander emerged with two armed guards flanking him.
“Clara,” Alexander said with false warmth. “I was hoping you’d come. We have so much to discuss.”
She studied Alexander’s face, looking for any sign of guilt or remorse over what he’d done to his brother. Instead, she saw only cold calculation and barely concealed irritation, as if Marcus’s escape had been nothing more than a minor inconvenience.
“Where is he?” Clara asked, letting genuine emotion bleed into her voice. “Where is Marcus?”
“Dead, I hope,” Alexander replied casually. “My men reported that the mansion caught fire during the operation. Terrible tragedy. I’m afraid there won’t be much left to identify.”
Clara felt a stab of fear despite knowing it was a lie. If Alexander believed Marcus was dead, it meant he’d lost track of him during the escape—which could be good or very, very bad.
“But you survived,” Alexander continued, gesturing for her to precede him into the lighthouse. “Lucky you. Though I have to admit, I’m curious how you managed to avoid the fire.”
“I hid,” Clara said simply. “In the basement. When the shooting stopped, I ran.”
Alexander’s smile didn’t reach his eyes. “And you came here because…?”
“Because I know who you really are now,” Clara said, allowing anger to sharpen her voice. “I found the laboratory. I know what you did to Marcus.”
“Ah.” Alexander nodded approvingly. “Good. That saves us some time.”
He led her into the keeper’s house, where Dr. Crenshaw waited with a briefcase full of vials and documents. The woman was older than Clara had expected, probably in her late fifties, with iron-gray hair pulled into a severe bun and eyes as cold as the instruments she carried.
“So this is the famous Clara,” Dr. Crenshaw said smoothly. “The variable that turned an obedient subject into a liability.” Her gaze was clinical, appraising Clara the way one might examine a specimen. “I look forward to seeing whether you can succeed where Marcus failed.”
Clara forced herself not to flinch. “I’m not your experiment.”
Dr. Crenshaw smiled thinly. “Oh, my dear, you already are.”
Behind them, Alexander shut the door with a decisive thud. The sound echoed through the old stone walls like the sealing of a tomb.
