In order to become a London taxi driver, you must pass "The Knowledge," a very difficult test that requires you to master no fewer than 320 basic routes, all of the 40,000 streets that are scattered within the basic routes, and approximately 20,000 landmarks and places of public interest that are located within a six-mile radius of Charing Cross. After only four years of study, Ian Beetlestone passed, and here he replicates this remarkable test, and this homage to London also contains color maps, trivia, and fun anecdotes.
