In 1937 Freddie (English), Isabella (Italian) and Oskar (a German Jew) become friends at an art school in Florence where they are taught by the dictatorial but magus-like Maestro and his sinister fascist assistant Fosco. When war arrives Freddie returns to England to become the pilot of a Lancaster bomber. Oskar, now a dancer, has moved to Paris where he escapes the 1942 roundup of Jews and arrives in Italy with his young daughter Esme. Isabella remains in Florence where she continues to paint. Until she is called upon by Maestro to forge an old master painting, apparently at the behest of the Führer himself, and as a result is seen as a Nazi collaborator by her neighbours. 

The murderous skies over Germany and a war-torn Italy in the grip of Nazi occupation provide the setting for this novel about the love of a separated husband and his wife and the love of a man for his young daughter. Freddie and Oskar both hope to find their way back to Florence. But Florence's heritage of preserving the identity and continuity of the past has never before been so under threat.
