There's no use locking the doors ... It was the case that nearly killed him. Now a gruesome discovery in an underground chamber is about to resurrect his worst nightmare. And Massachusetts State Police detective Bobby Dodge has only one lead: a young girl who's been in hiding for as long as she can remember. There's no use turning on the lights ... Her childhood was a blur of new cities and assumed identities. But from who -or what- was Annaabelle Granger's family hiding? To find out, Dodge must team up with former lover and partner D. D. Warren from the Boston P. D. to track a woman from Bobby's past who's every bit as dangerous as the new killer. The trial will lead them to a chilling place where there's no one to trust ... and no place left to hide. The killer knows where to find you.
