The Bad:
Now for the good points:
Henri Loevenbruck delights us with a wonderfully neat feather and deliciously medieval narrative style by a skilful mixture (the narrator addressing his player) and prose, sometimes subtly antiquated, sticking perfectly at the time.
The story of a flamboyant originality, starting from the discovery of a mysterious forgotten room right inside the house of the apothecary, take us on an exciting quest, exciting and full of twists of Paris in the Sinai through by Compostela.
With a dazzling mastery emerges a powerful story, scholar, extremely well documented, but still easily accessible. A tour de force.
The characters are very believable with psychological depth and a "thick" genuine.
An admirable philosophical reflection and thought patterns of confrontation looms in shading throughout the story between symbolic and Gnostic Christianity, between scientific approach and esoteric beliefs.
In short: A wonderful historical thriller that has nothing to envy to the masters of the genre.
