Doppelganger

Pursued by police as a suspect in her mother's murder, shy, retiring Holly Gooding moves to Los Angeles and finds safety with a young screenwriter, Patrick Highsmith. But what Patrick doesn't know about his alluring new roommate is that inside that beautiful body reside two, diametrically opposed personalities: one, a timid young girl; the other, a killer -- with an unquenchable appetite for sex and murder.
