The Sieur Gaston de Luynes is a soldier of fortune whose fortunes haven’t worked out so well at the beginning of The Lovers of Yvonne. Almost destitute, he was lucky enough to be hired by Cardinal Mazarin to teach his nephew Andrea de Mancini arms. But in the first chapter of the novel, the Cardinal fires Luynes after Andrea becomes drunk, blaming Luynes for his nephew’s behavior.
More dangerously, Andrea, who is a very young man, has been challenged to a duel. The Cardinal orders Luynes to make sure the duel doesn’t occur. The only way Luynes can see to honorably do that is to injure the other combatant, Eugène de Canaples, first. So, he duly insults Canaples and then handily beats him in a duel, making sure to wound him.
However, this fight attracts a mob, which chases Luynes with the object of hurting him. He is only able to escape by jumping into the carriage of a woman passing by. He falls madly in love with this woman, who unfortunately is Yvonne Canaples, the sister of his victim.
If this weren’t bad enough, the Cardinal informs him that he has arranged a marriage between Yvonne and Andrea. He tells him he will see him hanged if he finds him anywhere near Choisy, where the de Canaples live. But Luynes likes Andrea, so when invited to go along with him, he does. It’s a good thing, too, because several other suitors are on the way there, most notably the Marquis de St. Auban.
This novel is Sabatini’s first, and it is full of intrigue, sword fights, and kidnappings. Sabatini had only lived in England ten years before writing it, but the English is impeccable, his sixth language. Although Sabatini was himself disappointed in this novel, it is entertaining.
