Prince of Foxes is a 1947 historical novel by Samuel Shellabarger, following the adventures of the fictional Andrea Orsini, a captain in the service of Cesare Borgia during his conquest of the Romagna. Plot introduction Andrea Zoppo, an Italian peasant schooled in the arts and versed in the ways of nobility during his University years, conceals his old identity during the French invasion of Florence, and becomes Andrea Orsini, a bastard member of a dead Neapolitan junior branch of the great house of Orsini. Having made his name with the French forces, he takes service with Cesare Borgia, with dreams of uniting Italy to stop the depredations of foreign adventurers and the manipulations of France and the Holy Roman Empire. However, his love of Lady Camilla of the Bagliones and respect for her husband Lord Varano of Citta del Monte derail those plans when he is sent to their court to take the city by treachery.

He uses Mario Belli (Marius de Montbel, lately of Savoy), erstwhile nobleman, traitor, and assassin of some repute. Mario fails, but, a true "modern," turns his coat and offers information. Finding him intriguing and useful, Orsini spares him and offers him a place in his retinue. By force of his personality, Orsini overawes the d'Este ambassador and makes his way to Ferrara. On the journey, Belli secretly discovers Andrea's true heritage. In Ferrara, despite the interference of Duke Ercole d'Este and his impetuous son Cardinal Ippolito d'Este, and the resistance of the cannon-happy Alfonso d'Este, he accomplishes his mission, securing Alfonso's
