Who stole the hamster from Room 11? A once-happy class is set on edge in this humorous， highly relatable mystery perfect for middle-grade readers.The day the hamster disappears from Smashie McPerter’s class begins like any other. Well， except for the fact that the teacher is out sick and Smashie’s class is stuck with Mr. Carper， the worst substitute in the world. And except for the mysterious business with the glue. And except for the fact that Smashie is wrestling with a terrible problem， which only partly stems from her extreme aversion to hamster feet. As the peaceable and productive days of Room 11 turn into paranoia-fueled chaos， as natural suspects produce natural alibis and motives remain unmotivated， Smashie and her best friend， Dontel， are forced to the limits of their parlor-room detecting to set things right.
