Following

A struggling, unemployed young writer (credited as "The Young Man") takes to following strangers around the streets of London, ostensibly to find inspiration for his first novel. Initially, he sets strict rules for himself regarding whom he should follow and for how long, but he soon discards them as he focuses on a well-groomed, handsome man in a dark suit. The man in the suit, having noticed he is being followed, quickly confronts the Young Man and introduces himself as "Cobb". Cobb reveals that he is a serial burglar and invites the Young Man (who tells Cobb his name is "Bill") to accompany him on various burglaries. The material gains from these crimes seem to be of secondary importance to Cobb. He takes pleasure in rifling through the personal items in his targets' flats and drinking their wine. He explains that his true passion is using the shock of robbery and violation of property to make his victims re-examine their lives. He sums up his attitude thus: "You take it away, and show them what they had." Read more on Wikipedia.
