Katharine is sure that someone is playing a trick on her as the doorbell continues to ring only to find no one there. Her cousin Crockett suggests that it could be the vanishing man and mom and dad seem to think she has a hearing problem. Katharine is certain it is her friend Vanessa and sets out to get proof. The proof does not turn out to be easy to find and it certainly does not go as she planned. Katherine locks herself out of her house and ends up in real trouble with her parents. Being a detective is not as simple as it seems. It appears the mystery will never be solved, until one rainy evening, in the midst of an electrical circuit homework project the pieces to the puzzle of the ding dong ditch finally begin to unravel. Katharine learns that things are not always what they seem. Yet another delightful addition to the "Katharine the Great" series, early chapter book readers will love the feel of reading a big kid book. The font is large and the spacing perfect for readers making the transition to the next step in reading fluency. Katharine's adventures continue in the titles The Write Stuff, The Artsy-Fartsy Auction and The Purr-fect-o Present. Katharine finds herself in dilemmas that early readers can relate to and make connections with. An engaging read that would be perfect for classroom literature circles. Reviewer: Kathy Leggett
