A true thriller novel that kept me engaged and captivated as a whole. However, at some point I had to put the book down for long a while due to the lack of progressing events. Apart from this, the book is perfect, the characterization is so accurate that a true visualization of the characters is being embodied in my head. The choice of Argentina, a third world country like mine, as a setting for the novel gives a trait of randomness greatly felt to the extent that I recreated the whole events and assigned equivalently parallel places, people, local names in my home country. For a moment I was thinking that maybe an Arabic adaptation for this novel would be written. Yet, it would be a hugely controversial book. What touched me the most was the protagonist's pursuit of truth even though he knows what would be the end of him; the inner conflict between his good and evil sides were perfectly demonstrated. The protagonist's character was not, like mainstream thrillers, flawless and void of weakness. At some point, the whole world he has created, lived in, and believed wouldn't have come to existence if he had given up on himself. The search for truth was a guide and an uplifting motivation represented in the quotes and the wise sayings that cannot be uttered except by an old man whose face has been portrayed by life's lessons and whose mind has grown old in unraveling the complications and the mysteries of the human nature just through looking into their eyes and listening to their truths and lies.
