Chapter 3
"To put you in a cage," you whisper, your voice rasping.
"Because you couldn't bear the thought of anyone else holding the key," he corrects softly, his gaze locked onto your mouth. "Because from the moment we crossed paths in that alley behind the exchange, you knew we were the only two people in this city operating on the same frequency. You despise my methods, Christian, but you crave my mind. You crave it like a dying man craves water."
"You're a sociopath, Sterling."
"And you're an addict," he fires back instantly. "A brilliant, starving addict who has spent two years keeping my dossier beneath your mattress. Did you think I didn't see the light burning in your apartment at three in the morning? Did you think I didn't know you kept the architectural sketches I left behind at the harbor warehouse?"
Your breath hitches hard. You hadn't logged those sketches into evidence. You told Miller the office was swept clean. Instead, you had locked those ink drawings in your personal desk, spending midnight hours tracing the precise, elegant lines of his blueprints, terrified by how intimately you understood the mind that drew them.
"You were stalking me," you accuse, your hands dropping to your sides, your knuckles whitening.
"I was waiting for you," Nathan whispers. "I was waiting for you to catch up. And tonight... tonight you finally did."
He raises his cuffed hands. Before your exhausted reflexes can fire, he hooks the iron chain over your head, letting the cold links drop against the nape of your neck.
The metal bites into your skin, but the heat of his forearms, bracketing your face, is scalding.
"What the hell are you doing?" you hiss, your hands flying up to grip his wrists. His pulse is hammering beneath your fingers—wild, rapid, perfectly matching the frantic beat in your own throat.
"Look at the board, Christian," Nathan breathes, his face inches from yours. You can smell the faint trace of almond soap on his skin, the sharp metallic tang of his sweat. "Look at what you reconstructed. The window rig. The liquid nitrogen. The spliced network loop."
"It's an ironclad case," you say, your voice trembling as your fingers dig into the meat of his forearms. You should shove him off. You should slam him back against the chair and call the floor sergeant. But the weight of his arms around your neck feels like a brand, locking you into his gravity. "You made three mistakes, Nathan. And I caught every single one."
"Did you?" Nathan whispers. His eyes drift down to your lips, lingering there with an aching deliberation that makes your knees feel hollow. "The network splice in the alley. If the restaurant’s feed switches to a local loop, there's a forty-millisecond packet discrepancy with the city’s telecom trunk. Did you find that discrepancy in the central log?"
You frown, your detective’s instinct fighting through the sensory haze of his proximity. "The buffer absorbed it."
"It absorbed it on the primary line," Nathan murmurs, his thumbs shifting to brush lightly across the stubble of your jaw. The touch sends a fierce, electric shiver down your spine. "What about the secondary municipal bridge? The one that runs an automated integrity handshake every ten minutes?"
You freeze. Your mind races through the technical logs you cross-referenced at dawn.
There was no dropped handshake.
"Why didn't the handshake flag it?" you whisper, the instinct of the hunt overriding your common sense.
Nathan smiles, the curve of his lips pressing against your cheek as he leans closer. "Because the loop wasn't spliced into the restaurant's line. It was routed through an unmapped copper junction box under the storm drain. The municipal bridge never saw it."
He pulls back just enough to hold your gaze, his gray eyes shining not with the panic of a trapped killer, but with the quiet, ecstatic pride of a craftsman admiring an equal.
"You missed that," he says softly. "Your timeline was perfect. Your deduction was sublime. But the district attorney would have dropped the wiretap warrant the moment my defense brought an engineer to the stand."
You stare at him, your chest heaving, the chain heavy against your neck.
"You're fixing your own indictment," you say, the sheer madness of it turning your stomach into knots. "You're sitting in my interrogation room, facing life without parole, and you're coaching me on how to convict you."
"I told you, Christian," Nathan whispers, his fingers tightening against the back of your neck, pulling you down until his lips are mere millimeters from yours. "If I am going to be destroyed, I will only let your hands hold the hammer."
The sheer arrogance of it makes your blood sing. A dark, possessive hunger uncoils in your chest, sweeping away the last remnants of your badge, your oath, your caution. He isn't fighting you. He is offering himself to you, laying his brilliant, monstrous intellect at your feet.
"You think this is theater," you growl, gripping his shirtfront with both hands, twisting the fine cotton in your fists until the fabric strains. "You think you can turn my room into your stage. But when that door opens, Nathan, the state is going to crush you. The law doesn't care about your elegance. It cares about Gabriel Thorne's body."
"Then let's finish it," Nathan whispers, his breath hot and ragged against your mouth. "Thorne's panic room. The solid steel vault door. Thorne locked himself inside the moment he heard the hoist. How did I kill a man through eight inches of hardened armor plate?"
The air in the room suddenly feels thick, charged with the heavy, metallic static that precedes a lightning strike.
"You didn't open the door," you say, your voice dropping into a harsh, intimate cadence. "You knew Thorne’s medical history. You knew he suffered from severe cardiac arrhythmia."
Nathan’s eyes narrow with razor-sharp intensity. "Go on."
"The panic room draws independent air from a dedicated roof intake," you whisper, leaning down until your forehead nearly touches his. "You didn't use poison. The chemical sensors would have tripped within seconds. You used an aerosolized stimulant—a synthetic epinephrine derivative. Odorless. Invisible. Harmless to a man with a healthy heart. But for an elderly man having a panic attack in an enclosed space? His heart detonated within five minutes."
Nathan’s breath catches hard.
"And the puncture wound at the base of his skull?" he asks, his voice barely audible.
"Post-mortem," you whisper, your grip on his shirt tightening as you press him back against the chair. "You waited for the scrubbers to clear the air. You used the master bypass key you stole from his security architect six months ago. You walked in, used a micro-gauge cannula to sever the spinal artery to make sure he was dead, took his encrypted ledger, and walked out."
The silence in Room 4 stretches until it feels like glass about to shatter.
Nathan doesn't speak. He stares up at you, his eyes wide, glistening with an emotion so raw, so violently tender, that it strips away every defense you have left.
"You saw it," Nathan whispers, a quiet, broken sound escaping his throat. "Every move. Every breath. You mapped my entire soul on that table."
