Inspector Specter (Haunted Guesthouse Series #6) in Bloomington, MN

Just when she thought she’d seen everything…
Detective Lieutenant Anita McElone is one of Harbor Haven’s finest. She’s also a hard-boiled ghost skeptic. So when she shows up on the doorstep of Alison Kerby’s Haunted Guesthouse to ask for supernatural help in solving the murder of her former partner, it’s hard to tell which woman is more flabbergasted. But McElone is dead serious, so Alison promises to help in any way she can—even asking her resident ghosts, Paul and Maxie, for help with the case.
As Paul’s spirit source reveals some troubling information about the deceased detective, Alison wrestles with what to tell McElone. First, though, she has to find her…because the lieutenant has suddenly disappeared.
