Guardian Artangel books podcast: Maya Jasanoff

In the fifth of our dispatches from A Room for London – a hotel installation in the shape of the boat in Joseph Conrad's novella The Heart of Darkness – we hear from award-winning historian Maya Jasanoff. 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 on the theme of London, rivers and/or Conrad. Jasanoff talks to Maev Kennedy about her time on the boat, and reads her exit essay, "A River Passage".
