Afterimage is a crime novel by the American writer Kathleen George set in contemporary Pittsburgh, Pennsylvania. It tells the story of two murders, one of a woman and one of a child, that seem to be unrelated. Richard Christie, Head of Homicide, takes on the case, as in George's two previous novels in the series, but in this book a rookie female detective, Colleen Greer, is introduced as a key player.
