The Bones of the Magi

During a festive service at Cologne Cathedral, a mass murder occurs: all parishioners die a painful death. The criminals, clad in monastic robes, steal a priceless relic that has been kept in the cathedral since the 12th century - the bones of the biblical magi. A team of special agents from the secret organization "Sigma", led by Gray Pierce, is sent from Washington to investigate the crime. Together with scientists from the Vatican, the group manages to establish that the Imperial Order of the Dragon - a secret brotherhood of alchemists with roots going back centuries - is involved in the murder and theft.
