Codes, Puzzles, and Conundrums
The fourth book in the trilogy is now available! (Well, a companion book that makes an ideal present for a know-it-all relative — or a precocious child whom you want to keep quiet for a few hours…)
Enter the world of secret codes, cunning puzzles, and mind-bending conundrums. Inspired by the Raising Arcadia series, this book offers a step-by-step guide to each type of problem and then a quiz to test your progress. Use it to hone your own detective skills, or to baffle your friends and relatives.
