Demon in a Box

When Peter Heller unravels the opening code of an old music-box size ancient box he is utterly surprised when a scantily dressed beautiful young woman pops out of it. Yasmin, as she says is her name, tells him that she is a 'fallen demon' and that by releasing her from a five-hundred years of confinement he had turned her into a human and she will therfore become his devoted slave.
Despite his fascination with Yasmin's prolific sexual ministrations, subservience, and great wit, Peter slowly comes to the realization that she is not the kind of person that she pretends to be. His suspicions are confirmed when Peter is visited by the Devil, who tells him about Yasmin's great evil.
