Chapter 9
Thirty-six hours. You have been in this windowless, airless concrete tomb with him for thirty-six straight hours. It is only natural that your brain is misfiring. Sleep deprivation induces auditory and sensory hallucinations; you memorized the manual back at the academy.
You aren't losing your mind.
You are winning.
"Thirty-six hours, Nathan," you say, your voice flat, raspy, but vibrating with an electric undercurrent of anticipation. You round the table slowly, pacing the length of the concrete floor. The rubber soles of your oxfords squeak against the linoleum. "You've given me eight different versions of your timeline between midnight and two in the morning. You've offered three separate alibis, all verified by burner phone pings that coincidentally routed through relay towers with faulty timestamp firmware."
Nathan offers a faint, mocking smile, though the tremor in his lower lip betrays him. "Technology is unreliable, Christian. You know that better than anyone. A faulty relay tower is a municipal failing, not a confession of murder."
"Don't call me by my first name," you snap, though the casual familiarity sends a hot, perverse shiver straight down your spine.
You stop behind his chair. You can smell him—not just the precinct’s stale air, but Nathan's scent. Expensive cedarwood cologne curdling with sweat, the bitter aroma of adrenaline, and the underlying warmth of a body pushed to the absolute edge of physical endurance.
It is intoxicating. For months, this man has been a phantom, a whisper of impossible financial heists and untraceable corporate assassinations. He moved through the high-security citadels of the elite like a ghost, leaving behind perfectly constructed suicides and accidental overdoses that no one else in the department had the brains to question.
Only you saw the pattern. Only you recognized the signature of a terrifyingly arrogant mind treating the physical world as a chess board.
And now, he is sitting in your room. Bound to your table.
"You're deflecting," you murmur, leaning down until your mouth is inches from his ear. You see the fine hairs on his nape stand on end. "You deflect every time I bring up the eastern terrace of the Thorne Penthouse. Why is that, Nathan? Why does a man with an alibi three miles away turn pale whenever I mention a rooftop garden?"
Nathan shifts his weight. The iron chain of his handcuffs clinks against the table ring. "Gabriel Thorne is an eccentric billionaire with an army of private security contractors and enough automated defense systems to repel an airborne battalion. If someone penetrated his penthouse, they were either a miracle worker or an idiot with a death wish. I am neither."
"No," you say, straightening up and walking back to the front of the table. You pick up the thick, beige manila folder resting near your lukewarm coffee cup and slam it down in front of him. The sound cracks through the small room like a gunshot. "You're an artist. That's your fatal flaw, isn't it? You can't just kill a man. You have to make it an impossibility. You have to prove that no fortress built by human hands can keep you out."
Nathan doesn't look at the folder. He looks at your throat, watching the steady, heavy throb of your carotid artery.
"You flatter me, Detective," Nathan whispers. "Is that part of the interrogation manual? Seduce the suspect with intellectual praise until he rolls over?"
"I don't need to seduce you," you say coldly, though your chest tightens at the word. "You're already naked on this table. You just haven't looked down to notice."
You flip open the folder. Glossy black-and-white crime scene photos spill across the scratched laminate: high-resolution schematics of the Thorne Tower, thermal sensor logs, wireframe floor plans, and autopsy photographs of a man whose heart stopped while sitting in an armchair behind five inches of ballistic acrylic.
Nathan’s gaze flickers downward, despite his best efforts to maintain eye contact. His pupils dilate.
You catch the micro-expression instantly. A tiny, imperceptible hitch in his breathing. A twitch in the tendon along his jaw.
"Let's talk about the impossible," you say, pulling out a red grease pencil. You lean over the table, planting both hands flat on the surface, invading his space until he is forced to tilt his head back to look at you. "Gabriel Thorne was found dead at 01:14 AM. No forced entry. No biometric bypass recorded on the retinal scanners. No kinetic vibration picked up by the floor sensors in the corridor."
"Heart failure," Nathan says quickly. His voice is a little too thin, a fraction of an octave higher than before. "The coroner's preliminary report cited acute myocardial infarction."
"Preliminary being the operative word," you counter, circling the layout of the penthouse with the red pencil. The wax tip screeches against the glossy paper. "Until the toxicology screen came back from the state lab three hours ago. Potassium chloride, delivered via a micro-puncture to the sublingual vein beneath his tongue. Undetectable unless you lift the tongue with forceps and use ultraviolet dye."
Nathan’s jaw tightens. A drop of sweat rolls down the curve of his temple, catching the fluorescent light before dripping onto his collar.
"Fascinating," Nathan murmurs, his knuckles whitening where his hands are clasped over the iron ring. "A ghost story. But as the district attorney reminded you before you dragged me in here, a clever murder without a delivery mechanism is just an unsolved case. You have twelve hours left before you have to charge me or let me walk. And right now, you don't even have a broken window."
"I don't need a broken window," you whisper. You pull out a chair, drag it across the concrete with a shrill screech, and drop into it directly across from him. You lean in, your knees brushing against his through the thin fabric of your trousers.
The contact is electric. Neither of you pulls away.
For thirty-six hours, you have existed in this crucible together. You have smelled each other, screamed at each other, stared into the deepest, darkest crevices of each other's minds until the boundary between interrogator and suspect began to blur into something twisted, something ravenous and suffocating. You want him behind bars; you want to tear his arrogance to shreds; and yet, the sheer brilliance of the man has pulled you into an orbit you cannot escape.
"You're right about one thing," you say, your voice dropping into a low, hypnotic register. "The biometric locks were never touched. The elevator was locked out at the lobby. The maintenance shafts are lined with infrared tripwires that would fry the power grid if a rat crossed them. That left only one possible avenue of approach: the exterior glass facade of the eastern terrace."
Nathan lets out a ragged, dry laugh. "The eastern terrace? Are you serious, Christian? The terrace sits on the forty-second floor, suspended four hundred feet above the financial district. The shear winds alone would rip a climber off the glass."
"You didn't climb," you say.
"Then I suppose I grew wings? Or dropped from a parachute into the most heavily monitored airspace in Manhattan?"
"You used a carbon-fiber descent line from the construction crane on the adjacent tower," you say, tapping the schematic. "A six-hundred-foot pendulum swing, calculated to the exact millisecond to match the blind spot of the maritime radar sweeping the harbor."
