If you love books with action, suspense but not too much (if at all) psychology of the characters, while "The third door" is for you. This is an adventure story where there is a billionaire with a crazy project, an Egyptologist, a doctor and even a énigmologue, if, if, a specialist in riddles, the kind of guy that studies the existence of Loch Ness, who spends his nights in famous haunted mansions, who questions everything that seems strange or unexplained ... And then all these people left for an unknown destination to bah ... and, precisely, we do not really know what they want but we doubt that it is a treasure, or solving a legendary enigma, short, sturdy and fantastic thing. So share issue, there will be spoiled, it rocks well and there is even a supernatural edge, but the characters are still damn bland ... except their name and profession, we do not know much of them. Overall, this novel is readable quickly and easily but we should not expect much depth.
