Books with title The Great Brain reforms,

The infamous Great Brain is home for summer vacation and ready to swindle anyone in Adenville, Utah, foolish enough to make a deal with him. The same money-hungry mind that built Tom's reputation as the Great Brain is undimmed by his year at the Academy. In one short summer Tom tricks his friends out of almost everything of value that they own, outwits three clever confidence men, and finally sets up business as a river raftsman. But when, to make 30 cents, Tom endangers the lives of two friends, his brother, J.D., decides it's time for The Great Brain to reform. And that's how the trial of the kids of Adenville vs. The Great Brain took place in the Fitzgeralds' barn one summer day.

Tom Fitzgerald, alias The Great Brain, is back, struggling to stay reformed now that his friends have threatened to ostracize him if he puulls even one more swindle. But his brother J.D. knows Tom's reformation is too good to be true, and as a reformed Great Brain makes for a dull life, J.D. is not altogether unhappy--or blameless--when his brother's money-loving heart stealthily retums to business as usual.Under the watchful eyes of parents and friends, Tom has to be craftier than ever, and indeed he is. Whether he's cleverly pulling an out-and-out swindle so as not to be caught or solving a train robbery and murder, Tom's Great Brain never fails.

The Great Brain is Tom D. Fitzgerald, aged ten. 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.
