Final Curtain is a 1947 crime novel by the New Zealand author Ngaio Marsh, the fourteenth in her series of mysteries featuring Scotland Yard detective Roderick Alleyn. It was published in Britain by Collins and in the USA by Little, Brown. Although set in a large English country house, immediately after the 2nd World War, it is effectively one of Ngaio Marsh's crime stories with a theatrical setting, given that it concerns Alleyn's wife Agatha Troy accepting a commission to paint a portrait of the great actor Sir Henry Ancred in the role of Macbeth, onstage at the theatre of his ancestral home, Ancreton Manor, to be unveiled at his 70th birthday party, amongst his family, most of whom are actively involved in the London theatre, one way or another. The novel was well received and reviewed. Source: Wikipedia (en)
