When Sadie Kramer agrees to help decorate for San Francisco's high-society Halloween shindig, she expects to find whimsical ghosts, skeletons, and jack-o-lanterns when she shows up at the Wainwright Mansion, not a body. Especially not the body of the woman in charge of the charity event.

With two detectives, a paranormal investigator turned television star, and a cauldron full of Wainwright Foundation staff and family members cackling around her, Sadie and her sidekick Yorkie are determined to find out who the killer is. Will an old legend help lead to the truth? Or will this simply become one more tale in the mansion's haunted history?
