Thubway Tham is a small, short-tempered gnome of a man, a professional pickpocket with an annoying lisp. But he is no mere thief... he is the king of his chosen profession, a master "dip" who works only in the subways of New York City. Like all such villains, he faces a cunning adversary in Police Detective Craddock, who is always half a pace behind. Craddock has sworn to put Tham behind bars, where he belongs. But Tham is clever enough to always remain one step ahead of Craddock and everyone else.Despite being a criminal, Tham always comes off well: the people whom he relieves of their wallets are often deserving of it, and he has a tendency to take on other, much worse crooks to give them their just desserts. And, of course, there are scoundrels aplenty in his world: a rival pickpocket who moves in on his turf in "Thubway Tham's Baggage Check;" Shifty Shane, the holdup man, who calls Tham a coward because he doesn't use a gun; and Mr. Clackworthy, a slick grifter from Chicago, who looks down on dips as the lowest of thieves.Call him an early antihero. Tham endears himself to readers because he has a moral compass. He knows his place is in the gutter of the world, but that doesn't mean he can't strive to better himself -- or others.
