Mélo is a 1929 play by Henri Bernstein which premiered in the US in 1931 at the Ethel Barrymore Theatre.
Pierre Belcroix and Marcel Blanc are violinists and lifelong friends living in Paris in the 1920s.
Romaine carries on her affair with Marcel, even as Pierre falls ill, which she may have deliberately exacerbated with her treatment in order to murder him.
It was first filmed in 1932 by Paul Czinner in two versions: in Germany as Dreaming Lips and in France as Mélo [cy; fr; sh].
The 1986 French film based on the play was directed by Alain Resnais, and starred Fanny Ardant, André Dussollier, Sabine Azéma and Pierre Arditi.
