Hide — Lisa Gardner

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 Annabelle 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 trail will lead them to a chilling place where there's no one to trust...and no place left to hide.

This killer knows where to find you.
