o Calvi, known as "God's Banker," was discovered hanging under London's Blackfriars Bridge. What wasn't found was the briefcase he was known to have had with him the night before, reportedly stuffed with incriminating documents, a special key, and a computer disk filled with codes, which together unlock a piece of the Vatican's troubled past.

When the briefcase mysteriously reappears in the Vatican Secret Archives, Father Michael Dominic and his team-Hana, Marco, Karl, Lukas, the feisty young nun Sister Teri, and Dominic's new assistant, Ian-are up against two powerful and enigmatic organizations, Opus Deus and the ultra-secret, outlawed Masonic Lodge P2, who savagely fight for control of the briefcase and its contents. Their goal? To carry out one of the most dangerous conspiracies the Church has ever faced-all happening during an unexpected conclave to elect a new pope.

From Rome, Italy, to Geneva, Switzerland, join Dominic and friends as they fend off plotters, kidnappers, and blackmailers who have threaded their way into Vatican politics for decades, in a conspiracy known as The Opus Dictum.
