Candy is the old swamper character in John Steinbeck's Of Mice and Men. He sweeps out the bunkhouse and does general maintenance on the ranch where George and Lennie come to work. He lost one of his hands in a ranch accident. He is the first character the two meet when they arrive. In chapter two, Candy introduces the other characters on the ranch, including the Boss, Slim, Curley, Curley's wife and the black stable buck Crooks.
