Magnus, sent on an errand to Switzerland, meets two men who will be important in his life as a spy.

In the years between 1953 and 1959, Magnus betrays his father Rick and renews his acquaintance with Axel.

Magnus is living in the US and still bailing his father out of trouble, but after an interrogation he seeks refuge at the seaside.

With Magnus Pym working in Washington with Axel, the heads of GB and US intelligence argue over his loyalty. As Jack Brotherhood doggedly defends him, Pym finds sanctuary in a remote seaside town in England.

On hearing of Rick's death, Pym and Mary return to Vienna. Pym then rushes off to England but fails to return to Vienna as planned.

While Brotherhood and his agents search the Vienna house for clues to Pym's disappearance, Axel makes contact with Mary.
