Worse than historical novel

THEME
Paris, today. An old man is dead. But in his library, his daughter finds that black book supposedly written by Fulcanelli disappeared. The daughter of the old man entrusts Mc Ari, former agent of general information, the task of finding this famous book.

IMPRESSIONS
Although Loevenbruck insists on esotericism, I find less gifted on the subject, although it is better than D.Brown, as in historical novels (Apothecary).
Some passages are exciting, others are dragging on.
What is interesting is that the author "glue" to research on Fulcanelli. We feel that he is fascinated by the mystery. But that night a little scenario testing because sometimes takes over the novel.

STYLE
The style of Loevenbruck is always good in the plot, BUT Research Fulcanelli in "typewriter style" in the text is too large for a novel, and night over the action.

END
The identity of the rider surprised me.
