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.
Griffin uses humor to tackle issues most children grapple with at some point, and Hindley’s loose b&w sketches play up the madcap energy at Rebecca Lee Crumpler Elementary School. Smashie’s … positive energy and determination are impressive. Readers will be learning and laughing heartily as Smashie dons her “Investigator Suit” and uses “thinking power” to try to prove herself
The story is well written and evenly paced, with great supporting characters to root both for and against. … A gentle and humorous mystery for younger middle grade readers.

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.

N. Griffin’s charming book, SMASHIE McPERTER AND THE MYSTERY OF ROOM 11, solidly combines a day in the life of a normal third grader with some kid-level, hard-boiled sleuthing. Accompanied by a collection of illustrations by Kate Hindley, this book balances itself as an adorable and wonderfully character-driven story.
This fine story of investigation and discovery is perfect for advanced elementary to middle school leisure readers.
Smashie is a unique and engaging heroine, and her relationship with the likable Dontel is credible and endearing. Plentiful humor in the colorful characterizations and amusing phraseology (“The children waved their outerwear like pitchforks”) make this an excellent readaloud selection as well…. Kids moving up from Cam Jansen will find Smashie an entertaining next step.
