An ancient loan made by Pope Pius VIII wreaks havoc in the present. The new religious conspiracy thriller featuring Cal Donovan.

While browsing the Vatican libraries, Harvard professor Cal Donovan uncovers a secret that could bankrupt the Catholic church. Unearthing evidence of a 200-year-old loan which the Vatican owes to a Jewish bank, Cal deduces that, with centuries of interest behind it, the sum now amounts to a crippling 25 billion Euros. With the future of the Vatican at stake, Pope Celestine asks Cal to intercede with the Sassoon family to whom the sum is owed.
