Chapter 2

The third ring hadn't finished before Enzo recognized the pattern. Three rings, then silence, then the soft click of a call being ended—not a message, not a voicemail, just the sound of someone testing whether he was still alive to answer.

He'd used the same signal himself, years ago, when the city still moved to his command. A quick call, no voice, to confirm a man was where he was supposed to be. The fact that someone was using it on him meant the old world had not forgotten the old rules.

Enzo wheeled himself toward the desk, the movement smooth and practiced—twelve years of muscle memory from shoulders and arms that had grown strong out of necessity. The phone sat on the polished surface, dark and silent. He picked it up, checked the log.

No number. Blocked.

He put the phone down and looked at Dr. Harlow, who had not moved from the wingback chair. The doctor's face was the color of old paper, and his hands still trembled on his knees.

"Who runs your lab?" Enzo asked.

Harlow blinked, slow, like a man surfacing from deep water. "My—what?"

"Your lab," Enzo repeated. "The panel you ordered twelve years ago, when I first collapsed. The one that supposedly confirmed the stroke. Who ran it?"

Harlow's brow furrowed. He was thinking now, grasping for the thread. "I don't—it was a private lab. Standard referral. The results came back, and they were consistent with a vascular event."

"And in the last twelve years," Enzo said, "how many times did you reorder blood work? Tox screens? Anything that would have caught a neurotoxin?"

The silence stretched.

Harlow looked at his hands. Then at the floor. Then at the toxicology report on the walnut table, bold header facing him like an accusation.

"Once," he said, barely audible. "I ordered routine blood work once. The results were normal."

"Normal," Enzo repeated, tasting the word. "A man who can't move his legs has normal blood work, and you never wondered."

"The standard panels don't screen for industrial toxins," Harlow said, and to his credit, he didn't try to justify it with excuses. His voice was flat, clinical, the voice of a man admitting the limits of his own care. "There's no reason to run them unless you suspect poisoning."

The study went quiet. The furnace hummed. Somewhere in the house, a door opened and closed.

"And you never suspected," Enzo said.
