The haunting of Heck House

Monster-mashers and babysitters extraordinaire Cheryl and Tweed are back, along with their friends Pilot and Artie--and they're in trouble again! This time, they're tangled up in some ghostly goings-on: solving the mystery that lies behind the creepy doors of Hecklestone Manor, Wiggins Cross's only genuine haunted house. The gang must face off against a whole new host of horrors, including gargoyles, possessed drive-in movie speakers, and a gaggle of ghoulish ghosts. At the same time, Cheryl and Tweed must defend their babysitting turf against the rival sitters in the town--in a contest of wits, guts and sitter-fu!
