After years of hiding in the Thackery family house, Sid the skeleton is delighted to finally have his moment in the spot-light. Every day, Georgia Thackery's daughter, Madison, brings in his skull for her high school production play of Hamlet and every night, she takes him home... Until one night when he's accidentally left at school-and hears the sounds of someone being murdered. But the next day, there's no body and no one seems to be missing. Sid is not a numbskull -- he knows what he heard. Georgia believes him, but no body has been found. Now Georgia and Sid will both need to keep their heads as they stick their necks out and play sleuth to catch the killer.
