These were some of my most favorite mystery books when I was little. My kids have enjoyed reading this one.
Suspects who are identical twins...A leaking tent...Magical worm pills...A zebra's portrait...And a sheet of toilet paper from Spain that's been swiped. These are just some fo the ten brain-twisting mysteries that Encyclopedia Brown must solve by using his famous computerlike brain. Try to crack the cases along with him- the answers to all the mysteries are found in the back.
