Divided into five short chapters, this offers a classroom-centered mystery that is accessible to new readers. Jeffrey Bones takes pride in his ability to unravel mysteries, not addition problems. During a math test, Bones spends his time daydreaming before slapping down random numbers as answers. When his teacher hands back the tests, Bones' paper is missing. Opening his detective bag, Bones applies his mind to the case and finds his paper. It takes a retest, though, to provide a happy ending. The fifth book in the Bones series, this offers a portrayal of the young sleuth kids can identify with.

Gr 1-2 Detective Bones is back in his sixth beginning-reader mystery. He loves writing the letter "J" (his first name is Jeffrey) and he hates math tests. While taking one, he struggles through what may be termed a numerical panic attack and just writes down numbers. His exam, however, is missing, and his teacher asks him to take it again. Putting on his detective hat, Bones eventually solves the puzzle of how it disappeared and opts to retake the test now that he can think clearly about addition. Expressive color cartoon illustrations on each spread support the easy text. Bones's many fans will enjoy watching him put his detective skills to work once again, and newcomers will also be caught up in the case. Linda M. Kenton, San Rafael Public Library, CA
