By using their eyes to ferret out clues, four kids calling themselves the Black Hand Gang catch a stamp forger, a jewelry burglar, a drug smuggler, and a cockatoo thief. The gang's peripatetic sleuthing takes them onto trains and through tunnels, down alleys, to the zoo, and underwater; and readers are whisked along with them and required to do their own searching in the crowded drawings that face every page of text. The clues are ingeniously planted, sometimes easy to miss but always obvious once you've extracted the answer from the next page of text. In that, they're a lot more reasonable than the ones Encyclopedia Brown one-ups you with. And, though Press' art and writing wouldn't shame the average TV cartoonist, the Black Hand Gang's machine-gun pace and viewer involvement just might grab a few hot-media holdouts that the Sobol series hasn't reached.
