Join the novelist for a discussion of writing and their latest book. Francis Spufford’s Cahokia Jazz takes place in 1922, in an America that never was, when two detectives find a body on a roof. A delicate peace holds in the city of Cahokia, but that body is about to spark off a week that will spill the city’s secrets and bring it either to destruction or rebirth. Spufford talks to writer Tiffany Murray.
