Who Killed Purity Mather?

A self-proclaimed witch sends Burke a record predicting her murder, along with a list of suspects. When her body is discovered after a fire, she has been disfigured by acid, leaving only a clue of a tattoo. The design of the tattoo matches that of an amulet carried by her pet raven. For likely suspects, Burke has to choose between a less-than-imposing "vampire", the head of a nudist colony, the "reincarnation" of the Goddess of Love, a wealthy man obsessed with spiritualism and his compliant companion, and a con artist/fakir. Before the case is solved, Tim saves Burke from a "brush" with death!
