The same night, in London, Captain Francis Blake, head of MI5, is made aware of this spectacular escape and goes to the United States to help the FBI track Olrik down, while his friend Professor Philip Mortimer receives a letter from Doctor Géorgios Markopoulos, curator of the Archaeological Museum of Athens, asking for his help on an extraordinary case.
The Professor retrieves the box as well as a stater of the reign of the Emperor Tiberius, putting immediately an end to the storm, then returns to the Museum.
Meanwhile, at the headquarters of the FBI in Washington, Blake is meeting with John Calloway, Chief of special operations, and his assistant, Jessie Wingo.
They have traced the origin of the helicopters of the escape of Olrik until a certain Belos Beloukian, wealthy Armenian businessman and so-called former prisoner of war.
In Athens, Dr. Markopoulos explains to Mortimer the reason for his coming: he fell in possession of manuscripts indicating that in the 1st century a.d., the leader of a Christian congregation in Greece, named Nicodemus, had met Judas Iscariot, who failed his suicide mentioned in the Bible.
The Inspector Kamantis is highly advised to leave the city for safety, and in the early morning, Mortimer, Jim and Eleni take a train to the South of the Peloponnese.
Meanwhile, on a small island in Mediterranean, Olrik enters in a room decorated with a large Nazi swastika where Beloukian chairs a meeting vowing to become the masters of the world.
Beloukian then confesses to be Colonel Count Rainer von Stahl and hired him as head of the service of information and security, as it did to Basam Damdu.
After vainly searching the Chapel, Mortimer and Eleni visit a young shepherd, but Olrik and Jack are already on the spot and escape with the manuscript.
Mortimer catches Olrik and take the manuscript, but Jack arrives and is about to kill him when Jim comes in and puts him to flight.
Mortimer warns Blake of the presence of Olrik in Greece and finds Eleni who tells their next destination: the island of Syrenios.
Mortimer drifts for several days at sea until he is saved by a seaplane with on board Blake, John Calloway, Jessie Wingo and a commando of the MI6.
In the evening, they board it, but it's a trap and Rainer von Stahl, watching them from the side, orders the launch of a torpedo that destroys his ship.
In view of the means available to Rainer von Stahl, it is clear to Blake and Jessie that he is supported by an organization such as the ODESSA and the former SS members.
A ray of light envelops Judas who thanks the Lord before falling to dust while a lightning bolt strikes Rainer von Stahl who catches fire.
