Vampire David Talbot lobbies Merrick to call Claudia's spirit and slake Louis's guilt, but Talbot winds up in the grip of an obsession with the witch. You see, Talbot, unlike most vampires, lived 70 years as a human, so his sexual response to humans is still as strong as his blood thirst. Merrick can cast spells to make men crave her, and Talbot is tormented.
Another one of Anne Rice's books, which tie together The Vampire Chronicles and the books about the Mayfair Witches. A surprising twist from most of her vampire books, there is almost no queer content in this book. At most, we learn about David Talbot's relationship with another man when he was a mortal.
