Marianne Hackett



Agent and leading investigator for Biomorphic Predatory Diseases Agency (BPDA), and also a big-game vampire hunter. After reading Malcolm Frye's claim over the internet of seeing his supposedly deceased former Wrenfield High classmate Karl Todman at his new school Mansbridge Academy, she immediately suspects that there are vampires in hiding there or within the vicinity, and determines to prove it. She also suspects that Dr. Reginald Murdoch is behind all these suspicious activities at Mansbridge, but it is unclear whether her apparent attraction to him is fake or sincere.
