The fourth plague

In the shadowed grandeur of a crumbling palazzo in Siena, the Festini family preserves an aristocratic legacy built on pride, vendettas, and dangerous alliances. Old Salvani Festini is a formidable patriarch whose influence reaches far beyond his decaying home, and whose connections to secret societies have drawn the attention of the Italian government.

During a tense midday meal, his two sons question him about the mysterious Red Hand—a name that inspires fear and suspicion. The younger son is handsome and idealistic, while his older brother watches in thoughtful silence, each confronting the peril surrounding their family. As rumors of conspiracy gather, the household becomes a meeting point for nobles, spies, and ruthless men who believe justice is best delivered outside the law. Set against the atmospheric streets and historic shadows of Tuscany, this mystery combines family intrigue, secret organizations, and the ominous threat of a hidden enemy.
