1203. Constantinople is besieged ... by the Christians of the 4th Crusade! Under cover of night, a small group of knights flees the doomed city. They're taking three mysterious chests to Antioch - but never reach their destination. Nowadays, in Rome, Agent Reilly has come with a Professor Sharafi to request access to the Vatican's archives. But once inside, he reveals that the document they're here to consult is one that the Church doesn't want anyone to see...
Reilly has tracked down the fake Professor Sharafi to Turkey. But the
man is crafty, and not only does he manage to escape, he also
recaptures Tess along the way. A chase begins across the hills of
Cappadocia, with the FBI agent hunting down his enemy while Tess, in
order to survive, does her best to follow the trail of Knight Templar
Conrad and the mysterious treasure he was protecting - the one
everyone thought was a threat to all of Christianity...
