The Sword by Daniel Easterman
Professor Jack Goodrich has a prestigious job in Cairo and a happy family life with his wife and ten-year-old daughter. When he's offered the chance to authenticate potentially priceless artefacts, including a sword, he thinks his dreams have come true. But as soon as they are in his possession, the nightmare begins with the death of his wife and daughter. The sword appears to be the property of the descendent of the Prophet Mohammed, and the people who want it will do anything to get it. Once the descendent has it he will declare jihad on all non-Muslims. Only a strange, beautiful woman known as Scheherazade can help him. Together they must decide what to do with the sword and try to prevent the destruction of the world as we know it.
