Situated high in the Pyrenees the monastery of St. Lazarus is a forbidding place. Behind its ramparts and battlements it hides a secret so dangerous its keepers will kill to protect it. At the end of a bitter winter, a delegation headed by the ambitious Inquisitor Rainiero Sacconi arrives to investigate the monks of St. Lazarus.

It is the year 1307 and the ancient Order of the Knights of Christ and the Temple of Solomon is in grave danger. The King of France and Pope Clement V are plotting its destruction and scheming to appropriate the Order's most sacred and dangerous secret. This is taken away by Etienne de Congost, a battle-weary but incorruptible man who flees through a world in ruin, dodging plots and papal spies in a life-and-death struggle. Will he keep the secret from the evil hands of king and pope?

A cryptic invitation brings Grail historian Otto Rahn to an apartment in Berlin. What awaits him will change his life. What ensues is a hunt for Le Serpent Rouge, a notorious book of black magic written by a Pope, a book Himmler wants to add to Hitler's library.
