The place of happening is Rome, in September 1683. While the Turkish army spends on the borders of the West and opens Vienna, the sudden death of a passenger at the inn in the center of the Holy City invites the panic: is it a poison or plague?
From the fear of infection, the quarantine was inaugurated in the inn and the guests were imprisoned in their rooms; Among them is Abbot Ato Melani, a ghost and secret agent in the service of Louis XIV, determined to discover what lies behind this unusual death.
His investigation will, however, reveal a terrible secret, an international conspiracy in which religion, politics and espionage are intertwined.
In an atmosphere of baroque Rome full of uncertainty, among secret underground corridors and alchemical laboratories, hunter-dogs on relics and illegal printing, strange medical and culinary recipes, an unimaginable aspect of Europe’s history – emerges a great plot managed to reconstruct historical times of Middle Ages.
