 By the time we meet him, he is twenty-five, and has lost the lobe of one ear and gained a diagonal scar across his left shoulder.When we last see him, he is in jail for hitting a policeman, but thanks to his sterling work uncovering tenement scandals, has been offered his old job back for a hefty rise in pay.An alumnus of Wrykyn, where he was once given six of the juiciest by Sam Shotter for stealing jam sandwiches from the school shop, Mr Bates grows up to be a thoroughly unpleasant sort, avoiding old acquaintances for fear they may touch him for cash and trying to kiss girls he believes to be under his power.
