John Lanchester talks to James Naughtie and a group of readers about his novel Capital, which was a major BBC TV drama in 2015.

The residents of an affluent street in London are busy getting on with their lives when one day something strange happens. Every house in the street has an identical, mysterious postcard pushed through their letterboxes that simply states "'We Want What You Have.'

At first, the residents of Pepys Road, who are from mixed racial and social backgrounds, dismiss the notes as some sort of marketing campaign but gradually as events begin to escalate it becomes clear that there is more to this strange occurrence.

John Lanchester is a successful financial journalist as well as novelist. The novel covers multiple contemporary issues in British life including the financial crisis of 2007-08, immigration, radical Islam, celebrity, and property prices. In Capital, there is always mystery at the back of the reader's mind.

Presented by James Naughtie with contributions and questions from a group of invited readers.
