At the start of this novella the protagonist, Thibaut, is ambushed by Wehrmacht soldiers between the ninth and tenth arrondissements. That the year in 1950 is not the strangest aspect, as he is rescued by the appearance of the Vélo, a bicycle-like contraption with a queasily organic prow. It is, in fact, a living version of Leonora Carrington’s 1941 sketch ‘I Am an Amateur of Velocipedes’.
