Alain Patissier is a French teacher who teaches French in a British public school. He lives in the suburbs of London with his charming wife, Sophie, and his son, Roland, and he firmly believes his life is perfectly normal. Nevermind the fact that he looks at men during his Sunday runs. Nevermind the fact that his wife sometimes thinks he's a government agent. Nevermind the fact that he's still in love with the same person, despite not having seen him for ten years. Then, Henry Hirsch arrives. This is the story of the six months in which Alain's life was changed forever.
