It's early 1938, and Maisie Dobbs is back in England. On a fine yet chilly morning, as she walks towards Fitzroy Square - a place of many memories - she is intercepted by Brian Huntley and Robert MacFarlane of the Secret Service.
The German government has agreed to release a British subject from prison, but only if he is handed over to a family member. Because the man's wife is bedridden and his daughter has been killed in an accident, the Secret Service wants Maisie - who bears a striking resemblance to the daughter - to retrieve the man from Dachau, on the outskirts of Munich.
