Oxford honeymooners trace a vanished agent
In summer 1939 Richard Myles, a young Oxford don, and his wife Frances are asked to use their Continental holiday to find a British agent who has gone silent in the Reich. They follow a chain of contacts across Paris, Germany and into the Austrian Tyrol, each one passing them on through prearranged signals, until their cover collapses and they must escape Gestapo pursuit. The plot draws on MacInnes's own travels through 1930s Europe with her husband, and it serves as a case study of how quickly ordinary tourists become targets under a police state.
