Guardian Artangel books podcast: Michael Ondaatje

In the sixth of our dispatches from A Room for London – a hotel installation in the shape of the boat in Joseph Conrad's novella Heart of Darkness – we hear from the Booker-winning novelist Michael Ondaatje . For four days every month, as part of a year-long project by Artangel , a writer will stay in the boat, which is moored on top of London's Queen Elizabeth Hall, tasked only with writing an essay which explores London, rivers, the work of Joseph Conrad, or even all three.
