First, is meux caution readers that are usually put off by the use of the supernatural in a novel, because it gives him a very large place and, unlike a "simple" Thriller, is rather mid way between religious thriller and fantasy novel and horror. I who love these mixes genres, I have loved this scary cocktail satanic conspiracy within the Vatican, stalking a cursed manuscript through time and various top-secret religious orders. With this first novel, Patrick Graham realizes a true master stroke with a smooth writing and very visual, solid documentation, a daring plot, exciting and well done. Lovers of chills and thrills will be delighted with this stunning and terrifying suspense, from the 1st pages and up to the end, holds the reader spellbound and reaches many times its height in several scenes of horror anthology absolutely terrifying and a rare intensity, as I hadn 'read in a long time! So, even if there are sometimes some inconsistencies, facilities and large strings, they do not interfere at all reading pleasure, so this thriller is effective and panting. Roll on the next novel by Graham!
