Matthew Sweet picks over the bones of the Profumo affair with the historian Richard Davenport-Hines, author of a passionate new account of the scandal. There’s also a discussion of Gangster Squad – the latest love letter from Hollywood to the world of rackets, mobsters and molls. And to round things off in real style, Matthew talks to the writer, Michael Frayn, whose 80th birthday is being celebrated with a short series of radio plays including one of his best known works; Copenhagen.
