Dominique Aubry, a rich widow of 58, is found hanged on her barge in Neuilly. It appears that since the death of her husband on a trip to Mauritius, Dominique Aubry has been ailing. The case is shelved by the Nanterre court, which enters a verdict of suicide. But very soon the suicide theory is challenged. Dominique Aubry was extremely well-off and left an inheritance of 14 million euros.
