I'm back at the morning the detective knocks on my door. I remember exactly how this goes: the real culprit is the one who reported me first.

The door to the interrogation room didn't open; it exploded inward.

Lieutenant Marcus Garza, the commanding officer of Area One Homicide, stepped through the threshold with the subtle grace of a freight train. He was a broad-shouldered man in his late fifties, his silver-streaked hair cropped close to the scalp, wearing a tailored navy suit that strained against his wide chest. In his hand, he carried an active mobile terminal displaying an encrypted dispatch log.

"Miller," Garza barked, not looking at me. "Why is State's Attorney Vance sitting in my outer bullpen with two senior prosecutors and an executive protection detail?"

Miller’s face, which had barely begun to recover its color, went chalk-white for the second time that morning. "State's Attorney... Richard Vance? The victim's brother?"

"The victim's brother," Garza confirmed, his voice heavy with thunder. "And he's not here to grieve. He’s here because five minutes ago, an anonymous, high-priority cryptographic transmission was delivered to his personal secure server, the Cook County Public Integrity Unit, and the Federal Bureau of Investigation's Chicago field office."

Garza turned his coal-black eyes to me.

He didn't look like Miller; Garza was a political animal who had survived three mayoral administrations and two federal consent decrees. He recognized a chess move when he saw one.

"You Hayes?" Garza asked.

"Caleb Hayes," I said, offering a courteous nod. "Senior Architect and Managing Partner, Hayes & Mercer Digital Infrastructure."

Garza stepped up to the table, his gaze dropping to the matte-black drive resting between the water glasses. "Did you send a four-hundred-gigabyte file dump to the federal building at six o'clock this morning, son?"

"My automated servers did, Lieutenant," I replied evenly. "Configured on a dead-man's protocol. If my biometric signature wasn't refreshed on my home terminal by 6:30 a.m., the mirrors released the staging archives to five independent legal repositories simultaneously."

Miller let out a strangled, furious curse. "He played us, Lieutenant! He knew we were coming! He’s trying to poison the well before we can even process the physical evidence from his house!"

"Shut up, Raymond," Garza said coldly.

The room went dead silent.

Garza pulled a folding chair out from the corner, reversed it, and straddled the seat, resting his thick forearms across the backrest. He looked at me with cold, diagnostic calculation.

"You sent eighteen months of financial wire transfers," Garza said, ticking the items off on his blunt fingers. "You sent three hundred hours of unedited, multichannel audio surveillance recorded inside your own corporate offices. You sent forensic telemetry showing five distinct illegal access events into your home network from an IP address originating at 1100 North Lake Shore Drive."

"Julian’s penthouse," I supplied.

"Julian’s penthouse," Garza echoed. "Along with a time-stamped video from a commercial parking structure across from West Marine, showing Julian Mercer purchasing fifty feet of blue synthetic utility line, two pairs of heavy work gloves, and a set of size-eleven Red Wing work boots forty-eight hours before Victoria Vance was killed."

Miller took two stumbling steps back, his spine hitting the observation mirror with a dull thud. "That... that can't be right. Mercer was the one who brought us the vehicle identification! He gave us the license plate on the south road!"

"Mercer gave you what you wanted to hear, Raymond," Garza snapped, his voice dripping with disgust. "Because you're lazy. Because you saw a prominent socialite dead in a mansion, saw a business partner offering a clean suspect on a silver platter, and decided you didn't need to wait for the tire-tread analysis or the toll-booth transponders."

Garza reached down, picked up the black SSD from the table, and turned it over in his rough, calloused palm.

"There's just one problem, Mr. Hayes," Garza said, leaning in until I could smell the strong, minty tobacco of his chewing gum. "This drive explains the money. It explains the frame-up. It proves your partner is a calculating, thieving sociopath who wanted you to take the fall for his embezzlement."

Garza’s eyes hardened into black flint.

"It doesn't prove who swung the clock, Caleb. It doesn't put Julian Mercer inside that conservatory at one-thirty in the morning."
