Book excerpt: George H. Devol was the greatest riverboat gambler in the history of the Mississippi. Born in Ohio in 1829, he ran away from home and worked as a cabin boy at age ten. At fourteen he could stack a deck of cards. Over the years, he bilked soldiers, paymasters, cotton buyers, thieves, and businessmen alike. He fought more fights than anyone, and was never beaten. This is his story. Nobody was ever bored by it.
