Mr. Mortman

Mr. Mortman's only appearance is in book #8, The Girl Who Cried Monster. Mr. Mortman is a Librarian who happens to also be a Monster. Lucy finds this out one night and the whole book features trying to get evidence to prove this to her parents, and also trying to avoid contact with Mr. Mortman in the meanwhile. The book ends with Lucy's parents eating Mr. Mortman, since they are higher on the monster food chain than he is.
