Dame Ngaio Marsh , born Edith Ngaio Marsh, was a New Zealand crime writer and theatre director.
Internationally she is best known for her 32 detective novels published between 1934 and 1982. Along with Dorothy L. Sayers, Margery Allingham and Agatha Christie, she has been classed as one of the four original "Queens of Crime"—female British crime writers who dominated the crime fiction genre in the Golden Age of the 1920s and 1930s.
All her novels feature British CID detective Roderick Alleyn. Several novels feature Marsh's other loves, the theatre and painting. A number are set around theatrical productions (Enter a Murderer, Vintage Murder, Overture to Death, Opening Night, Death at the Dolphin, and Light Thickens), and two others about actors off stage (Final Curtain and False Scent). Her short story "'I Can Find My Way Out" is also set around a theatrical production and is the earlier "Jupiter case" referred to in Opening Night. Alleyn marries a painter, Agatha Troy, whom he meets during an investigation (Artists in Crime), and who features in several later novels.
Most of the novels are set in England, but four are set in New Zealand, with Alleyn either on secondment to the New Zealand police (Vintage Murder, Colour Scheme, and Died in the Wool), or on holiday (Photo Finish); Surfeit of Lampreys begins in New Zealand but continues in London.
