What appears to be a book isn’t a book at all, but a cleverly disguised safe, in which she finds a single rolled parchment, written in code.For encryption expert David Mallory, the text is impenetrable. Until an invaluable clue opens the door to a mystery, and a conspiracy, stretching back seven centuries, when the most powerful man in Europe declared war on the most powerful clan, the Knights Templar.Now, Jessop and Mallory find themselves on a global hunt for an unsurpassed treasure and this much closer to the keys to secrets that could change history, topple an empire, and bury them both alive. Because they’re not only the hunters. They’re also the hunted.
