A series of Math based mysteries to solve.

Bill Wise

Alongside Cal Q. Leiter and his police pals readers will solve a series of mysteries that revolve around math.

Despite the books name implying simpler more traditional puzzles, each mystery is an enjoyable longer-form narrative - often 4-5 pages - with illustrations that suit the tone of the book throughout. Puzzle-wise, the math is nicely weaved into the story. Readers use currency, unit measurement, and a variety of other methods to work with Cal on his solutions, and it's integrated in a way to not be too gimmicky.
