Who knows how a handleless teacup can point to a thief? What a pair of soggy sneakers has to do with three stolen fishing rods? How the word "Crabcake" can reveal the identity of a kidnapper?

Encyclopedia Brown knows?

The world's youngest supersleuth is here with ten brand-new solve-it-yourself mysteries to challenge and entertain his fans. Match wits with the ten-year-old detective as he and his junior partner, Sally Kimball, puzzle over brainteasers and coded messages, intrigues and whodunits. Their case load includes a perplexing calendar code, three water-filled canoes, a missing shopping bag, and a hundred-year-old treasure tree.

And if you're stumped, you can find out how Encyclopedia did it in the back of the book. But don't peek until you're really stuck!
