Gauthier of Flanders, the "Nomad", won Saint-Jean d'Acre. And the demons started their farandole around him, like Hakim the Black, dancer with both magical and destructive breath. But the worst is perhaps to come: if Gauthier is in St-Jean d'Acre, it is because he awaits his sister, Sybille, whose beauties have never sown anything but desolation and misfortune in the hearts of the beloved men. Jean Dufaux and Philippe Xavier lift the veil on the childhood of their hero, accelerating the rhythm of their demonic saraband.
