*What you don't know can kill you . . . * FBI Special Agent Sydney Fitzpatrick knows nothing about the Devil's Key, except that her father was involved in its theft twenty years ago and was murdered as a result. The Devil's Key, a list of seemingly random, supposedly indecipherable numbers, poses an immediate threat to national security—and anyone caught with this code in their possession is terminated with extreme prejudice. Sydney, unaware of the standing kill order, only just recovered the list and turned it over to her superiors—but not before making a copy. *What you do know can kill you . . . * Now the hard drive containing the list's data has been compromised and two civilians are dead. But Sydney's not the only one in danger. When a young woman with eidetic memory sees the numbers, Sydney and her partner, Zachary Griffin, must protect her—and what she knows—at all costs. For if the code falls into enemy hands, it could devastate the entire country's infrastructure—and even ignite a world war.

Covert agent Zachary Griffin and FBI Special Agent Sydney Fitzpatrick are sidetracked from an ongoing investigation to follow up on a potential lead. In a small Arizona border town, gunrunning and drug trafficking into Mexico are a part of the landscape - but not when they're orchestrated by an officer in uniform. At least that's the story told to agents Griffin and Fitzpatrick. But the dirty cop is now missing, and his sister says he's innocent, a victim of a corrupt police department. She is convinced they set him up to take the fall, then killed him, and she can prove it - with help from a highly unusual witness. Suddenly an open-and-shut case seems anything but, and the clock is ticking as Griffin and Fitzpatrick take on an entire police department in a deadly match that could go up in smoke at the last second.
