Booker shortlisted writer William Boyd speaks to Take Four Books this week about his new spy novel, The Predicament, and together with presenter James Crawford, and the crime writer Louise Welsh, they explore its connections to three other literary works. In his new novel, which is the second in a trilogy, travel writer turned accidental spy, Gabriel Dax, finds himself caught up in events in Guatemala, and then in Berlin, where he becomes aware of a plot to assassinate the charismatic, young president John F Kennedy. The stakes are high, the pace is fast, and Gabriel is finding the allure of his handler, Faith Green, difficult to resist.

For his three influences William chose: Mountolive, published in 1958, and which is the third volume in The Alexandria Quartet series by Lawrence Durrell; Len Deighton's debut novel The Ipcress File from 1962, this was later turned into a film, of the same name, starring Michael Cane; and John Le Carre's iconic The Spy Who Came In From The Cold published in1963.
