Malcolm always thought the librarian at the Franklin County Library was cranky. She constantly shushed him and insisted the library was haunted. Boy was she right! When Malcolm and Dandy have school reports to research, Malcolm's library book keeps disappearing and returning to the library! Could it be a ghost? It is up to the Ghost Detectors to get the library back in order! Calico Chapter Books is an imprint of Magic Wagon, a division of ABDO Group. Grades 2-5.
