Once in London, it quickly becomes clear to the reader (but not to Oliver) that the Dodger and his friends are an unsavory bunch. The old "gentleman," Fagin, trains kids to be pickpockets,and then he sells off what they steal. But Oliver doesn’t realize what’s up until he’s actually out with the Dodger and another one of the boys, named Charley Bates. Oliver sees the pair steal the pocket handkerchief out of a nice-looking old man's pocket. When Oliver turns to run away, the nice-looking old man sees him run and yells, "stop, thief!"
