The Buddy Files: The Case of the School Ghost (Book 6). By Dori Hillestad Butler. Albert Whitman & Company, 2012.
Buddy the Therapy Dog is on another case. The Cat with No Name alerts him that the ghost of the school does not want Buddy, or any of the kids attending the sleepover, to come down to the basement. Agatha the Ghost doesn't like it when children or animals hang out in what is considered to be her basement. Buddy wonders why Connor, his owner, Michael and Jillian got suspicious boxes with flashlights inside right before the fourth grade sleepover. With a storm thundering around them, Buddy and the kids try and communicate with Agatha... but do they find a real ghost, or something else?!
This book is amusing because it is told from Buddy's perspective and is full of moments showing the world the way a dog might view it. In addition to an easy to follow mystery, there are snippets of lessons and advice about the world, such as how making lists helps one to keep track of things, or about telling the truth. Butler really does a good job with slowly building up the excitement about what the mystery really is as Buddy finds more clues in each chapter.
