The explosive action kicks off as treasure-hunting FBI agent Ruth Warnecki is on the trail of stolen Confederate gold hidden in Winkel’s Cave in western Virginia. She never expects to find herself chin-deep in a grisly murder that leaves her nearly dead and rocks the town of Maestro. And at a stakeout in Maryland, FBI agents Dillon Savich and Dane Carver are nearly killed in a horrific explosion while attempting to rescue a kidnap victim, Pinky Womack. They are led to Arlington National Cemetery, where they not only find Pinky, but Savich also takes a fateful call on his cell from an old man out to kill both him and Sherlock. The thing is, they have no clue why. Pitted against an insane killer and his psychotic teenage girlfriend, Savich and Sherlock find themselves fighting a hate-driven villain with a very long and terrifying memory.
