Private detective Duncan Andrews's best friend Gina is a witch. His dog is a zombie. And his dead boyfriend, Robbie, is a ghost. So it's hardly any wonder that he uses his connection to the supernatural to help him solve cases. In Pale as a Ghost, Duncan's on the trail of a serial killer who may not be human, while also trying to move on in his dating life. In Animal Instinct, someone is using the skull of a powerful wizard—Gina's father—to control animals and attack young Ashton Marsh. In The Scarlet Tide, Duncan's latest case leads him to Chicago and a band whose members are all vampires. And in Dead End, Robbie's cousin Jason has moved into a house that's haunted by a serial killer, and Gina's on the run from witch-hunters. Through it all, Duncan must solve the case and balance a complicated personal life.
