Missing Person - Sarah Lotz

From acclaimed horror writer Sarah Lotz, hailed by Stephen King as "vastly entertaining," a new novel about a group of amateur detectives infiltrated by the sadistic killer whose case they're investigating.

Reclusive Irish bookseller Shaun Ryan has always believed that his older brother, Teddy, died in a car accident. It's only on his mother's deathbed that he learns the truth: Teddy, who was gay, fled the Catholic, deeply conservative County Wicklow for New York decades earlier. Shaun finds no sign of him in New York or anywhere else--until he comes across the unsolved murder of a John Doe whose description matches Teddy's.

Desperate for information, Shaun tracks down Chris Guzman, a woman who runs a website dedicated to matching missing persons cases with unidentified bodies. Through Chris's site, a group of online cold case fanatics connect Teddy with the notorious "Boy in the Dress" murder, believed to be one of many committed by a serial killer targeting gay men.

But who are these cold case fanatics, and how do they know so much about a case that left the police and the FBI stumped? With investigators, amateurs, and one sadistic killer on a collision course, Missing Person is Sarah Lotz at her most thrilling and terrifying.
