Pandora's Box is about to be opened...A brilliant, fast-paced thriller from the internationally bestselling author of the Bourne series.

The richest aristocrat in Italy is responsible for the documents' safety, but he's been marked for death by the Nazis. Some people want the secrets told. Some people want to plunge the world into a catastrophic holy war...
