The books of Franck Thilliez are addictive products that are expected feverishly next dose. Well here I am temporarily satisfied! We find Sharko and Henebelle like old friends, with whom we shared many meanders of life. Around them new characters are expanding. The ingredients that make the success of the author are waiting for you, well paced chapters, thorough research and well-documented, well-crafted plot and panting ... amateur complete the list at will. I found for my part in the search for the essence of evil, a recurrent topic in the odyssey of our flagship characters, our author joins his friend Maxime Chattam, in the way it addresses this theme in recent opus. A must read for those who have followed the adventures of our two cops, but for others, I would advise to start at the beginning, to get to know them ;-)
