One hour vanished from Detective Marcus Kane's life. He remembers kicking down the warehouse door, then nothing but blood on his knuckles and a corpse at his feet. No witnesses. No weapon. No memory. Now he's the department's most wanted, hunted by the brothers in blue who once had his back and tormented by jagged fragments of that stolen hour; fragments showing hands that move like his but aren't under his control. Then the second body drops. Same execution. Exactly one hour after the first. Marcus isn't just a suspect. He's a loaded gun in someone else's hand, and they're pulling the trigger on a schedule. Each victim ties back to a military black site that promised to erase his war trauma, not weaponize him into something unrecognizable. They didn't just take his memories, they programmed a killer into the void. His ex-partner Sarah believes him. Barely. She's risking everything to keep him one step ahead of the manhunt, but her faith cracks with every crime scene photo proving Marcus was there. And the killer inside him is waking up more with each passing hour. The facility's files are sealed. The doctors are dead. And Marcus has seventy-three minutes until the programming kicks in again. To stop the murders, he'll have to willingly step into the blackout and hope he comes back with answers instead of more blood. But his handler isn't some faceless bureaucrat, they're someone who knows exactly how to break him, because they built him. Marcus Kane has one hour to catch a killer. The killer is him. And the puppet master has been watching from inside his own department all along. *****
