Afterimage — Kathleen George

In the humid dog days of a Pittsburgh summer weekend, Richard Christie, Head of Homicide, faces not one, but two mysterious murders. The victims---a polite woman and an angelic child---do not seem to be connected in any obvious way. Christie is short-handed, the clues don't stack up, and he's got a rookie detective, Colleen Greer, to look out for. These are his problems.Colleen has problems, too. Her boyfriend is trying to break up with her, she's got a serious crush on her mentor, Christie, and it turns out she knew both victims slightly. Early in the investigation, she gets an alarming idea about the perpetrator's identity, but the man she suspects has no obvious connection to the victims. She has to move carefully with nothing but a gut feeling to go on---all the while disturbed by a series of memories of her own childhood.Kathleen George's novels have been praised for their subtle rendering of character and relationships---whether those relationships are among detectives or in the families of criminals. Boldly and elegantly written, Afterimage is a startling thriller.
