Angel Investigations' next mission finds them tracking a demon serial killer who preys on the city’s singles population. It's a burrower demon, a creature that possesses a host, finds its next prey then jumps to the new body - killing the previous host in the process.
During the investigation, Angel encounters undercover cop Kate Lockley. Kate, although sceptical of Angel’s vague credentials, becomes an essential source of information for the vampire. She’s pretty hot, too.
