Paris Nocturne - Tapa blanda

In the opening scene of Paris Nocturne, the nameless narrator is hit by a car near Place des Pyramides. He and the woman driving the car are taken in a police van to the hospital. He's sure he has met her somewhere. He is given ether, wakes up in a different hospital, and the woman, Jacqueline Beausergent, has vanished. A mysterious figure presents him with an account of the accident and hands him an envelope stuffed with bank notes. Does Jacqueline Beausergent have the answers to the narrator's questions about the past, about his father?
