On his sixteenth birthday, Peter Hithersay discovers that his father is not his father. His mother’s husband, Rodney, has wanted to dispel this misunderstanding for a long time, but it has taken years for Henrietta to say what has needed to be said.

In 1960 Henrietta was sent as a substitute to compete in a Bach festival in Leipzig, one of the most musical cities in the world. Bach lived there for twenty-seven years; Wagner was born there; other musical notables, such as Grieg and Schumann, have been associated with the city. But Leipzig, two hours from Berlin, spent forty years last century at the heart of the GDR, the police state of East Germany. Leipzig was the hub of one of the most unmusical régimes imaginable, and became a stronghold for the notorious secret police, the Stasi.
