The Angela Tapes

Industrialist and patron of the arts, Anthony Higham is found in the house of his mistress, Angela Chase, with his throat slit. Angela has disappeared. Bryon Loudon, winner of the Higham Prize and friend of Anthony, receives a tape cassette from Angela. She reveals that she was also the mistress of Anthony's two partners. She maintains that she is innocent of Anthony's murder but she cannot go to the police and she asks for Bryon's help. The police think that Angela is a serial killer, a text book psychopath.
