Christiane Sauvage

Sebastien Grenier, a former French spy, is working as a financial analyst in Zurich. However, his peaceful existence starts to disintegrate when he is recruited by a top French intelligence operative to discover how one of their own secret agents was found out and executed in broad daylight.

Roberte, 40, resistant during the war, Calvinist and anticlerical, is deputy to the chamber and inspector of Censorship. She married Octave, an old Catholic aesthete, professor of canon law, whom she saves from impeachment for collaboration during the war. He submits his wife to a perverse custom: the laws of hospitality or prostitution of the wife by the husband.
