In staggering clarity, the room watched him lean into the car. They watched him check the glove box, his movements quick and careless, papers shifting, the rental agreement pushed aside. They watched him check under the seats. And then they watched his right hand slide into the deep pocket of his yellow rain slicker, pause there for a fraction of a second, and come out again with his fingers curled around something small.
Carter touched the tablet, and the forensic playback software zoomed in automatically, smooth and merciless. The image tightened until O'Grady's hand filled the wall. It clearly showed his fingers pulling a transparent plastic bag containing a white, rock-like substance out of his own pocket. It showed the bag catching the light from the cruiser. It showed him deliberately, almost casually, dropping it onto the floor mat directly beneath the driver's seat, tucking it just far enough under that a man pretending to search would find it on the second look and call it a discovery.
"Well, well, well," the recorded O'Grady sneered, pulling his head out of the car, holding the bag up into the glare of the cruiser's headlights. "What do we have here?"
The interrogation room fell into a graveyard silence. The only sounds were the hum of the precinct's air conditioning and the heavy, ragged breathing of Officer O'Grady, who was no longer smirking, no longer leaning back, no longer in control of the air in his own chest. Miller had taken a step closer to the projected image without realizing he had moved, his face lit by the frozen light of the wall. Doyle had gone very still by the door, his arms no longer crossed, his hands hanging at his sides as if he had forgotten what to do with them.
"That," O'Grady stammered, pointing a trembling finger at the wall, "that's fake. That's doctored. You Kirkland and Ellis lawyers think you can come in here with doctored AI trash? I know guys who can make fake videos. That's not what happened."
His voice cracked on the last words. He tried to make it sound like contempt, but it came out as panic wearing contempt's clothes. He looked at Miller as if the captain might rescue him with rank alone, and then at Doyle as if a nod from his partner might make the wall go dark. Neither man moved to help him. Miller's eyes were still fixed on the projection, on the hand and the bag and the name tag glinting in the same frame.
Carter tapped the tablet again. The video paused, freezing on that frame, O'Grady's hand holding the bag of drugs right next to his own name tag, the letters O'GRADY, T. sharp enough to read from the back of the room. He let the image sit there while O'Grady's breathing filled the silence.
"This video is heavily encrypted with a rolling cryptographic hash to prevent tampering," Carter explained, his tone conversational, as if he were lecturing a dim-witted law student who had arrived late and unprepared. "Every second carries a signature that changes with the next second. Alter one frame and the chain breaks. Alter the chain and the server knows. It was not recorded onto a local hard drive that could be swapped or wiped or lost in an evidence locker. It was broadcast via a secure satellite uplink in real time directly to a server."
He paused, and the pause did the work of a raised voice.
"Specifically, a server located in the sub-basement of the J. Edgar Hoover Building in Washington, D.C."
Captain Miller's face drained of all color. The blood left it in a visible wave, from his forehead down to his jaw, until he looked like a man who had been standing too long in cold water. He looked at Carter, then at the two silent men in dark suits standing by the door, men who had not spoken, had not shifted, had not needed to, and finally at Cynthia Holloway, still seated at the steel table in her damp blazer, still in her socks, still watching him with an expression he could not read and did not want to learn to read.
"Who are you people?" Miller whispered, and the authority was completely stripped from his voice, leaving only a question that sounded smaller than the room.
Carter reached into his breast pocket and produced a sleek leather wallet. He flipped it open with a practiced flick, revealing a gleaming gold shield and a federal identification card, the seal catching the fluorescent light. Miller took the wallet with shaking hands. He read the credentials. He read the seal of the Department of Justice. He read the name and the title twice, as if the second reading might change them, and it did not.
"Deputy Director," Miller choked out. "I... I had no idea."
"I am well aware of what you don't know, Captain," Carter said, snatching the badge back with a smooth, final motion, closing the wallet and returning it to his pocket. "But my identity is the least of your concerns tonight, because I am not the ranking federal officer in this room."
Officer Doyle, who had been leaning against the doorframe trying to look tough, suddenly stumbled backward as if he had been physically struck. His shoulder hit the wall. His mouth opened, but no sound came out, only a thin, useless intake of breath. His eyes went from Carter to Cynthia and back again, and the calculation that had kept him standing all night collapsed in his face.
