I can't fully review this book because I threw it out after a few chapters. It's obviously a first effort by someone more schooled in accountancy than in writing. Every obvious device is employed. The protagonist does every stupid thing you can imagine. For example: his friend is murdered, he gets his hands covered with his friend's blood, he goes back to his friend's office while smearing his friend's blood (and his own fingerprints) on doorknobs and stuff. If I can recall, he took the weapon used on his friend and puts it back in his friend's office. C'mon. How stupid can a book get?
