When that shrewd conniver, Tom, the infamous Great Brain, is sent to school in Salt Lake City, his favorite victim, J.D., figures he can step into his brother's shoes as town hustler. Nothing's wrong with his technique - it's just that he hasn't got the instincts of a real con man. But when outlaws kidnap J.D.'s four-year-old adopted brother, Frankie, J.D.'s talents find their proper inspiration. And if everybody thinks it looks like curtains for Frankie, it's because they haven't counted on what a "little brain" combined with a big heart can do.

The Great Brain is Tom D. Fitzgerald, aged 10. The story is told by J.D., a sometimes confounded but always admiring younger brother. Such people as Mr. Standish, the mean schoolmaster, regret the day they came up against The Great Brain. But others, like the Jensen kids lost in Skeleton Cave, Basil, the Greek kid, or Andy, who has lost his leg and his friends, know that Tom's great brain never fails to find a way home.
