The Sixth Key

In late 2011 a cryptic invitation leads a crime novelist to Venice's Island of the Dead. Once there he is captivated by his host's tale, which spans the centuries - but seemingly begins and ends in the dark days of the 1930s . . . In 1936, a similarly cryptic invitation brings Grail historian Otto Rahn to an apartment in Berlin. Waiting for him inside is Hitler's right-hand man, Heinrich Himmler, and Rahn's life is turned upside down. For Himmler wants Rahn to locate Les Serpent Rouge, a notorious book of black magic written by Pope Honorius in the 14th century. Following a trail from Paris down to Carcassone in the South of France, Rahn discovers a web of deceit and murder. Clearly Himmler is not the only powerful figure in search of the grimoire. A shadowy circle of men are watching Rahn's every move, and they will stop at nothing to possess both the book and the legendary Sixth Key that will unlock its terrifying power . . .
