The series that keeps on giving (really, how long is it)... Juan tries to keep his distinct lack of valour during the failed siege of Forli a secret, and spins tall tales about his conduct on the battlefield. However, his lies quickly catch up with him when Caterina's son Benito Sforza, the hostage he condemned to death, turns up alive and well. Meanwhile, Lucrezia is given a new perspective of marriage, and Giuliano della Rovere struggles to replace the Pope's food-taster with his deadly apprentice. Historical drama, starring Jeremy Irons, David Oakes and Holliday Grainger.
