It's Halloween trick-or-treachery when murder pays a visit to a cursed mansion in the new Nick and Nora mystery . . . Waincroft Manor has long been tied to rumors of witchcraft and fatal curses, and to Nora Charles, that makes it the perfect place for a Halloween fundraiser. But her first trip to the deserted old mansion turns out to be truly ghoulish when she discovers a dead body. What's more, the corpse is laid out in a coffin—with two bite marks on its neck. Then the autopsy comes back showing that the body was drained of blood, and there's no stopping the local gossips from whispering the word vampire to anyone who will listen. Determined to dispel the rumors and save the fundraiser, Nora sets out to prove the murderer was quite human after all. Sifting through the clues, she learns of a bitter family rivalry that spans generations, and a more recent conflict that may point to the motive for the murder. And when Nick spells out a clue that proves to be the missing piece of the puzzle, Nora knows she'll have to watch her back—because there's a killer out there who wants to keep some secrets buried, and they'll happily bury Nora right along with them . . .
