The liqueur is made from a secret formula by Brother Antoine, who has just fled the monastery, taking the secret with him. En route to the city of Beni Mora, Algeria, Domini meets Antoine on a train, but he is silent. Later, in a cafe, Antoine is entranced by an exotic dancer named Irena. When Irena pulls a knife on her lover, Hadj, who will not marry her, Antoine helps Domini flee, and introduces himself as Boris Androvsky.
