About this book

On launch night at Silicon Valley’s most revered AI lab, the founder dies in a sealed room. The cameras swear no one went in; the autopsy says murder. Detective August Reyes, who trusts index cards over algorithms, has to prove a killing the perfect witness never saw.

The surveillance AI watched the founder die alone. The autopsy proves someone killed him. The footage is flawless—and impossible.

Detective August “Augie” Reyes works murders with index cards and his father’s fountain pen—because a ninety-four-percent facial-recognition match once sent an innocent man to death. On launch night at Silicon Valley’s most worshipped AI lab, founder Eli Roan lies dead in the sealed inner sanctum. ARGUS, the lab’s all-seeing surveillance system, says no one entered. The autopsy says a needle at the hairline stopped his heart. With the company reeling and the launch on a knife’s edge, Reyes must prove a murder that the perfect witness swears never happened.

Six insiders were locked inside with the body. Every one of them is lying. The impossible security footage is a flawless forgery, and the city is already asking the question that could scorch the whole industry: Did the AI kill its maker? Reyes doesn’t trust the machine’s answer—or his own certainty. He rebuilds the night from the things no one bothered to fake: a white orchid bought in the rain, rain falling on a dry night, a dead man’s honest blood. The killer left no trace. Except the ones that mattered.

A locked-room murder mystery with a ticking clock—twisty, atmospheric, impossible to guess.

Perfect for fans of Michael Connelly and Tana French.
