“Smashie will endear herself to many readers. . . . A gentle and humorous mystery for younger middle grade readers.” — School Library Journal

The day the hamster disappears from Smashie McPerter’s class begins like any other. As Room 11 descends into paranoia-fueled chaos, as natural suspects produce natural alibis, and as motives remain unmotivated, Smashie and her best friend, Dontel, are forced to the limits of their parlor-room detecting to set things right. Griffin writes a consistently smart book, layering subplots and red herrings on her central mystery and unapologetically using $20 vocabulary. She carefully provides context clues that will help her young middle-grade audience understand challenging words, introducing Smashie's discomfort at "the weight of [her classmates'] unjust censure" with the crystalline observation that they "were angrier at her than ever!" A singularly appealing group of kids populates this nifty mystery for readers ready for a challenge.

Readers will have fun going with Smashie’s flow—her custom-made outfits (“Investigation Suit,” “Distracting-Adults-from-Messes Suit”), shaky logic (“A little soft creature should have little soft feet!”), wrongheaded accusations, and triumphant redemption. Black-and-white illustrations throughout display Smashie’s individuality and verve.

Smashie is a unique and engaging heroine, and her relationship with the likable Dontel is credible and endearing.
