Twentieth Century Paris is more of a literary companion than a guide: a roll call of creativity, based on wide research, with a wealth of anecdote. In 1938 James Joyce invited Peggy Guggenheim and Samuel Beckett to dine at Fouquet’s, which was, surprisingly, his favourite restaurant — when he could afford it. Thirty years earlier, Lenin had tried to keep warm by making one drink last all evening at La Rotonde. But any reader attempting to navigate from one venue to another will need a different guidebook, since the chapters are not arranged by district but by themes — ‘Exiles’, ‘Flappers’ or ‘The Lost Generation’. There are a number of omissions — Sybille Bedford, Mavis Gallant and Arthur Koestler — while Julien Green and Christopher Logue make only nominal appearances.
