An elite team of assassins are back at it again. While on a dangerous quest to identify and execute a band of rogue vampires and their sovereign before they kill more humans, the Enforcers sneak into their informant's apartment in the middle of the night. A corpse with its mouth frozen open in a scream lies on the living room floor in a pool of blood. Their informant, Scummer, is dead, and it is obvious that whatever killed him had no mercy.
Bane "Vanity" Hellblazer is a Deadly who has learned to roll with the punches. But when the Graces move into the Deadlies' house to hide from an overzealous celebrity reporter, Bane soon realizes they are all bound to protect humans and supernaturals from danger. As the Deadlies attempt to identify the rogue sovereign vampire and find out who murdered their informant, Bane's twin brother, Demon, makes the Graces an offer they cannot refuse. As soon as the Graces agree to help, the Enforcers embark on a search for two missing gnomes-all while still attempting to fit in the usual executions.
In this continuing saga, a struggle for power ensues as Bane discovers there are sometimes drawbacks to being Demon's twin.
