The Fastest-Selling Book Of All Time
We look at the novel "50 Shades of Grey" and ask how the S&M book that's been slammed by critics and booed by feminists has become the fastest-selling book in UK history. Also on the programme: we meet another writing phenomenon of a different genre, Alexander McCall Smith. Plus, we discover World War I as seen by the great artists at the Pompidou Centre in Metz.
