 This was a much darker story than its predecessors, centering on a man who built a giant machine that could help him psychoanalyze his soul.Like the previous two books, it did not sell well; Vian's financial situation had been steadily worsening since late 1948, and he was forced to take up translation of English-language literature and articles in order to get by.Vian separated from his wife, and in 1950 he met Ursula Kübler (1928–2010), a Swiss dancer; the two started an affair, and in 1951 Vian divorced Michelle.
