Had documentary film-makers roamed the streets of London in the mid-19th century, they would have encountered an extraordinary range of characters. A rat catcher, a woman who sells dog dirt, and a depressed street clown are brought to life in this programme, capturing their tragic, amusing, and moving stories. Based on transcribed interviews with a wide range of working people as part of a survey of London labour and life by Henry Mayhew, the Victorian journalist and founder of Punch magazine.
