An undercover agent is tasked with protecting a computer code that threatens world stability in this suspense thriller.
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.
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.
