For a long time, the manuscript of the novel was considered lost. Thirty years after the author’s death, its publication makes it possible to grasp the full scope of the multifaceted work of one of the most significant writers of the twentieth century. The first completed novel both anticipates and, in a new light, illuminates everything that Perec would write later. The main conflict unfolds in the genre of a psychological detective: a virtuoso craftsman longs to become a true creator, conquer time, and rewrite history. The process of freeing oneself from this obsessive idea becomes the plot of the novel.
