"Stevie Diamond and her best friend, Jesse Kulniki, are back doing what they do best - solving mysteries. This time, the President of the United States is visiting Canada for a summit meeting when his dog is stolen from a local park. The Vancouver press attributes the crime to "the Prankster", a mysterious person who has been pulling mean practical jokes throughout the community. When the missing animal turns up at the dog daycare establishment where Stevie works, the detectives race to identify the culprit before someone thinks that one of them is guilty. Bailey has written another lively story that will keep readers involved to the very end." - School Library Journal.
