After detailing the impact of a financial meltdown in her new novel The Mandibles, Lionel Shriver asks why economics, once seen as a difficult subject for fiction, has become one of the most exciting and apocalyptic subjects for writers, artists and filmmakers. Lionel speaks to Damian Lewis, star of Sky Atlantic's Billions, about the realities of playing a hedge-fund manager, talks to writers John Lanchester and Paul Murray about the challenges of turning economics into literary fiction, and meets the makers of a new documentary presented by Terry Jones, Boom Bust Boom. Playwright Lucy Prebble makes the case that theatre is the best medium for exploring the subject, profiling current productions Boy and The Invisible Hand.
