It´s 5:38 on a March morning when Alex´s phone jars her awake. Homicide detective Mike Chapman is at the scene of a sexual assault and murder. It´s a perfect case for Alex and her special skills.

Policewoman Maureen Forester may discover some of the shocking answers when she volunteers to check into the hospital as a decoy with a supposed neurological
