Trouble According to Humphrey Reprint edition

Humphrey loves to solve problems for his classmates in Room 26, but he never meant to create one! Golden-Miranda, one of his favorite students, gets blamed when Humphrey is caught outside of his cage while she?s in charge. Since no one knows about his lock-that-doesn?t-lock, he can?t exactly squeak up to defend her. Humphrey really has his paws full when Don?t-Complain- Mandy-Payne and her family stir up more big trouble. Humphrey manages to help Pay-Attention-Art and Sit-Still-Seth and even survives a trip to the vet, but can he clear Miranda?s name without giving up his freedom forever?
