A New York State investigator matches wits with a devious serial killer in the New York Times bestselling author's true crime thriller.

Gary C. Evans was master of disguise and career criminal who had once befriended David "Son of Sam" Berkowitz. In 1989, he started weaving a web of deadly lies in Upstate New York, telling a female friend that the father of her child had deserted her. In fact, Evans had killed the man—just before striking up a ten-year romance with the woman.

Evans first met Investigator James Horton in 1985 when Evans snitched on a childhood friend and crime partner—failing to mention that he'd murdered him. Then, two local jewelry dealers were killed. In 1997, another old friend of Evans, went missing. Was Evans responsible? Horton launched a nationwide manhunt to uncover the truth.

For more than a decade, Evans and Horton maintained an odd relationship—part friendship, part manipulation—with Evans serving as a snitch while the tenacious investigator searched for the answers that would put him away. After Horton used Evans to obtain a confession from a local killer, Evans led Horton in a final game of cat-and-mouse that would culminate in the most shocking death of all . . .
