Robert Elms has seen his beloved city change beyond all imagining. London in his lifetime has morphed from a piratical, still bomb-scarred playground, to a swish cosmopolitan metropolis. Motorways driven through lost communities, murder miles becoming estate agents' dreams, accents changing, towers appearing. Yet still it remains to him the greatest place on earth. Elms takes us back through time and place to myriad Londons. He is our guide through a place that has seen scientific experiments conducted in subterranean lairs, a small community declare itself an independent nation and animals of varying exoticism roam free through its streets; a place his great-great-grandfather made the Elms' home over a century ago and a city that has borne witness to epoch- and world-changing events.
