Iain Sinclair, that master in his own words of “digging into where you are”, spent half a century making London his literary turf. More recently, he’s been digging in Peru, where he and his daughter Farne retraced an ill-fated colonial expedition led by his great-grandfather, Arthur Sinclair. The Gold Machine (2021), his account of their journey on the ground and into the darkness of Britain’s imperial past, goes into paperback this week, and a feature documentary opens in cinemas. While Sinclair goes on tour with the director, Grant Gee, Farne will be releasing a podcast, In Tropical Lands, on Apple Podcasts.
