America's favorite Sherlock Holmes in sneakers is back on the job and ready to outsmart the sneakiest crooks in town. Idaville might seem like a quiet place, but Chief of Police Brown knows that whenever a case gets too difficult, he can always rely on his ten-year-old son, Leroy, to find the answer. With a brain packed full of facts, Encyclopedia Brown sees the clues that adults walk right past. Now it is your turn to test your own detective skills against ten brand new mysteries. You will help Encyclopedia and his best friend Sally tackle neighborhood thieves, expose liars, and keep the local troublemakers in line. Each case is a short, interactive puzzle designed to make you think critically. You have to listen to the witnesses, observe the evidence, and catch the exact moment the guilty party tells a lie. It is a race to see if you can crack the case before Encyclopedia does. If the mystery proves too tough, the answers are neatly tucked away at the end of the book, ready to show you how a master detective really works.
