Let the author speak, p. 44: "What I wanted to do here is wander with Nestor Burma, let me bring in a Paris charged with historical and literary references I wanted to resume his routes, district after district ...." - hence a risk of paraphrasing and a pointillism; we would also have liked an overall reflection on the theme, present in literature from Baudelaire Forgot p. 45 in a list of "pedestrian Pais". The Paris N. Burma is now a part of Paris disappeared, we may regret (Les Halles), or forget (the fifteenth arrondissement). L. Bourdelas pass at the Paris trial of N. Burma by Léo Malet - his antisemitism is examined, especially pp. 78-85; but was it the subject, and is it wise to blame Malet, of not more, Isaac?
