Read stories inspired by the four Underground lines that run North and South through city - part of a series of twelve books tied to the twelve lines of the London Underground, as Tfl celebrates 150 years of the Tube with Penguin.
Comedy and capitalism join in four tales:
The Northern Line: William Leith, author of The Hungry Years and Bits of Me Are Falling Apart, tells, in A Northern Line Minute, the darkly humorous tales of his escapades on the Tube.
The Bakerloo Line: Paul Morley, author, journalist and cultural commentator, tells the story in Earthbound of post-punk, music and changing times.
The Victoria Line: Kids Company, a leading London charity supported by Prince Charles, Helen Mirren and Stephen Fry, presents the voices of some of London's children, in partnership with the charity's founder Camila Batmanghelidjh.
The Jubilee Line: John O'Farrell, author of The Man Who Forgot His Wife and An Utterly Impartial History of Britain turns his comedic genius to the problem of capitalism, encapsulated in a Tube train full of passengers stuck underground.
