They rather like bad boys, the French. Louis-Ferdinand Céline (1894-1961) is one, in a tradition that stretches from François Villon to the dyspeptic Michel Houellebecq. But provocation doesn’t always get you where you want to be, as the careers of Richard Millet and Marc-Édouard Nabe demonstrate.

Journey to the End of the Night, Céline’s first novel, was a huge success when it was published in 1932 and made him a darling of the left, with applause from Trotsky and Jean-Paul Sartre.
