In this marvelous work, Stephen Smith explores the life and history of London from an unusual angle—underneath. Beginning with the rivers that run under the capital and ending in the system of tunnels beneath the Thames Barrier, Underground London is an enthralling journey into a subterranean world. We find the author descending into St. Andrew’s crypts, where the dead are being raised; joining miners digging tunnels; and exploring the culverts beneath Hampton Court, a stunning feat of engineering designed as a secret passageway for Henry VIII’s mistresses. Smith visits Victorian sewers, wartime bunkers, and secret vaults. He explores tube stations and the now-defunct Mail Rail, the miniature railway that once transported twelve million letters a day.
