When Callum's superiors try to stop Victor, his life is threatened. Dieter finally tells Callum the truth about his past in Germany. The tables have turned, and it is now Dieter who tries to win over Callum. Harold similarly feels despair for failing to live up to Callum's expectations of him. Can these two men convince Callum of their integrity?

Kathy and Callum successfully prevent a war criminal from leaving the country, but is he too important to prosecute? Callum is instructed to get rid of all information pertaining to individuals of interest, while also having to court the imperious Frau Bellinghausen who holds the key to an infamous perfume. Callum juggles these new demands as his relationship with Rachel intensifies and becomes more compromising. Victor and Kathy make the most of Callum's distractions to find whatever his department has been hiding. Callum begins to realise that he is not the free agent he has always believed himself to be. Callum's dealings inside the hotel bring him closer to Harold, an ex-Foreign Office official and hotel regular, who reveals some startling truths about the outbreak of the war.
