Night Waves - Michael Holroyd, Bridget Riley, Thilo Sarrazin, Garry Trudeau

Philip Dodd talks to the biographer Michael Holroyd about writing his final book - part biography and part memoir, A Book of Secrets uses a fictional setting in southern Italy to recreate the lives of real people. The critic Sarah Kent joins Philip to review the National Gallery's new exhibition of work by the abstract artist, Bridget Riley. There's a discussion on immigration, multiculturalism and integration, looking at the controversial ideas contained in a best-selling book in Germany. Written by a former banker, Thilo Sarrazin, 'Germany Abolishes Itself' has been acclaimed for 'opening an important debate' and denounced as 'racist'. Philip is joined by the outgoing editor of Prospect, David Goodhart, and Cornelia Fuchs, London Correspondent for Stern magazine. And it's forty years since the cartoonist Garry Trudeau began his Doonesbury strip. He talks to Philip Dodd about how cartoons have evolved since he began Doonesbury in the late 60s.
