One night. One woman. One mistake that puts him in the crosshairs. Computer forensics expert Jack Rhodes thought he was helping someone in trouble. By morning, armed enforcers are breaking down his door—and a powerful criminal network believes Jack has something they want. Now he's running. The woman has vanished. The data she took could expose a multimillion-dollar operation built on fraud, corruption, and violence. And the men behind it don't ask questions. They eliminate problems. To stay alive, Jack must go undercover in the shadow world of San Francisco's criminal economy—where every move is watched, every ally is suspect, and one mistake means disappearing for good. They're hunting the file. Now they're hunting him.
