The last words of the book are: "to follow." Obviously, we have a little frustrated with the end, but if there is a sequence that gives the final solution to the enigma, why not. The novel is conducted on a very good pace, sometimes the word "thriller" is a bit overused because "thriller" expresses the fear, anguish, things I struggled to collect. Yet the whole story is coherent and has a Loevenbruck writing that flows well. Indeed, the novel reads very quickly and the characters are endearing, although somewhat stereotypical: the daredevil cop who wants to solve everything alone and likes his solitude sowing the love stories. The bodyguard, a former Miltaire who has seen all the colors, an ace combat, and faithful with that !!! Senior, a little stubborn, unable ankle cop. An unlikely killer out of a comic ... Well, some will say that the characters are a little too carricaturaux and therefore hyperprévisibles. All this does not spoil the reading, but again, it requires a suite, otherwise looks like another, it's "spritz". Half a disappointment or a half-success. Oh yes! Mackenzie, the cop does not like computers let alone the Internet. Suddenly, the puzzles are not solved by a single click on the Web. A happiness. Too many writers we bassinent with the Internet, as if all the enigmas of the world there was rescensés and resolved !!
