Ace Ventura meets the Addams Family! A shambling horde of new cases hits Dan Shamble, Zombie P.I. in the Unnatural Quarter. Dan and his gang-including his ghost girlfriend, feisty lawyer partner, cop best friend, and little vampire half-daughter Alvina-are out to seek justice, solve mysteries, and keep their heads on straight ... or at least attached. Alvina's singing lessons for the Banshee Tabernacle Choir end on a sour note when the troll choir director plunges to her death from a high belfry, and the only witness is a deaf-as-a-post gargoyle who sits too close to the loud bells. A frustrated imp, woefully unsuccessful in betting on the nightmare races, is dead certain that his bookie BatGN (GN for "gender neutral" to avoid copyright issues) is cheating him. Francine, the salty bartender at the Goblin Tavern, is worried when One Fang the vampire-her on-again, off-again suitor-disappears without a trace. A shady vendor discovers a market for living shrunken heads that are conversational as well as decorative, but the demand by far exceeds the supply. A heartless therapist has ulterior motives when she counsels zombies, distracting them from their woes to concentrate not just on brains, but on self-improvement as well. There is much at stake in the UnnaturalQuarter, and it's up to Dan Shamble to keep the streets dark and safe for monsters and humans alike. After all, the cases don't solve themselves! This zombie detective puts the P.I. back in R.I.P.
