Dan Shamble, Zombie P.I.10 books in series
Stakeout at the Vampire Circus Publisher's Summary
Zombie P.I. Dan Shamble and his ghost girlfriend are called to the Vampire Circus when a fortune teller’s cards go missing. Not exactly the glamorous life, but the stakes escalate when a vampire trapeze act goes dead wrong, and Shamble discovers even more skeletons in the closet than the ones that live there. As he shuffles for clues through an unnatural cast of carnies, he faces a slate of suspects that could freak out even the most daring detective - a werewolf lion tamer, a fat lady with an enormous secret, an undead ringmaster…and what could be scarier than a circus clown? The only thing certain is that the show must go on - dead or alive.
