"The only way to truly discover a city, they say, is on foot. Taking this to extremes, Mark sets out to walk the entire length of the London Underground - overground - passing every station on the way ... packed with historical trivia, personal musings and eavesdropped conversations, the author learns how to get the best gossip in London in a City pub, how the Ritz made its female guests feel good about themselves, and why the Bank of England won't let you join the M11 northbound at Junction 5"--From publisher's description.
