Barely escaping the clutches of a succulent succubus, Phaeton Balck returns to London only to get sucked into another unearthly scheme. Professor Lovecraft has been tinkering with the secrets of life and death, replacing body parts with the latest mechanical marvels.

Perhaps, bringing his lady friend along for the ride won't be to too much trouble. . .
