An unhappy game of romantic follow-the-leader explodes into murder one weekend at The Hollow, home of Sir Henry and Lucy Angkatell, arguably Christie's finest comic grande dame. Dr. Cristow, the Harley Street lothario, is at the centre of the trouble when, assembled in one place, we find his dull but devoted wife Gerda, his mistress and prominent sculptor Henrietta and his former lover and Hollywood film star Veronica. Also visiting are Edward and Midge whose romantic assertions are likewise thrown into the mix. As the list of romantic associations grows so does the list of potential suspects when Cristow is shot dead. Nearly everyone has a motive but only one of them did the deed.
