Two young men whose long friendship seemed to be unhealthily obsessive grew apart after an accident in somewhat murky circumstances. Years later, the mother of one of the young men, Thomas, gets in touch with the other, Clovis, who has become an investigative journalist, because Thomas, now a marginal, secretive director of conceptual films, has disappeared. Despite the somewhat obscure reasons that have motivated him, Clovis, agrees to investigate Thomas’s disappearance, thus reentering the life of his former friend. At the time of his disappearance, Thomas had been obsessively researching the life of his former next-door neighbor. Seemingly discreet and unexceptional, the man had been murdered in an exceptionally violent way. Following this trail in his turn, Clovis realizes that the life of the dead man – who had been intimately involved in the French Indochina War – had been far more complex than it seemed… Can the past be resolved by erasing any traces of it that are left? Can private or collective wounds be forgotten by rewriting history? The Flaw in the Sky is the tale of a man who, while searching for the truth about another man will discover that of a third: three intertwined fates corresponding to the underlying themes of doubles, identity and even schizophrenia… A novel about the long-term consequences of war in general, The Flaw in the Sky also deals specifically with the French Indochina War, which has been erased so quickly from French memory, and is rarely if ever addressed in French literature.
