When a Hollywood-based TV series schedules filming in Boston, Spenser smells trouble. When he signs up to protect the show's star, Jill Joyce, he knows it's on its way.

First, there's Jill herself. She's spoiled, arrogant, drugged out -- made worse by fear. Someone is out to get her -- does she imagine it, or is it real?

Spenser monitors her neurosis, but finds evidence of harassment. It escalates to murder. Now begins the dangerous part -- while the act may have ended, the murderer lingers on.
