The Jackal. A tall, blond Englishman with    opaque, gray eyes. A killer at the top of his    profession. A man unknown to any secret service in the    world. An assassin with a contract to kill the    world's most heavily guarded man. One    man with a rifle who can change the course of    history. One man whose mission is so secretive not    even his employers know his name. And as the    minutes count down to the final act of execution, it    seems that there is no power on earth that can stop    the Jackal.
