I found this book pretty average: not enough action, bounce, short suspense of it is a little bored. In fact the main character spends his time interviewing witnesses. It's very repetitive and little exciting ... Besides the style is sometimes a bit clumsy: the author adds very caricatured details that are of no use, it is sometimes called archi. Some positive points however: the hero is well designed, it is him that makes you go down the book, his assistant and its relationship with it are rather pleasant too. However, as I read in another review, I do not think that if this book had been written by another author would have benefited from a French translation.
