Praise for Tom Knox:'Tom Knox knows the DNA of an astonishing thriller. THE MARKS OF CAIN is a compelling and frightening novel, and it may well be the most controversial thriller since THE DA VINCI CODE. Action, history, religion, and genetics combine for a gripping read that will keep you reading late into the night.' Jeff Abbott, bestselling author of PANIC and FEAR'Steeped in both blood and history and keeps up a scorching pace from start to finish' Northern Echo'Knox writes with a clean efficiency. The characters are nicely wrought … Best of all, Knox really knows his stuff and his discourses on ancient man, human sacrifice, demons of the mid-east and obscure pre-Judaic religions are all woven into the plot seamlessly. I'm reminded of why I always liked these type of books, because not only do the best ones grip and propel you through their pages but they also leave you a little more knowledgeable than when you started' Shotsmag
