Lonely Hearts

"Lonely Heart" is the second episode of the first season of the American television series Angel. Written by David Fury and directed by James A. Contner, it was originally broadcast on October 12, 1999 on the WB network. In "Lonely Heart", Angel Investigations looks into a series of killings linked to a trendy L.A. singles club. While there, Angel meets Kate Lockley, an LAPD detective also tracking the serial killer - who believes, because of circumstantial evidence, that the murderer is Angel himself. After discovering the murderer is actually a body-hopping demon, Angel seeks Kate's help in tracking down the bartender, now possessed by the demon, and killing him. Kate, believing the bartender committed the murders, accepts a provisional truce with a circumspect Angel.
