Flavières, the staged suicide, and Marseille
Flavières, a Paris lawyer and former policeman with vertigo, is hired by his old friend Gévigne to shadow his wife Madeleine, who seems possessed by a dead ancestor who killed herself. Flavières falls in love with her. She climbs a church tower and falls while his vertigo stops him from following her up. Years later in liberated Marseille he meets Renée, who admits she impersonated Madeleine so Gévigne could throw his real wife from the tower, and Flavières ends by strangling her.
