Many newcomers to mysteries might look at the title of this post and wonder "who is this?" Ngaio Marsh (pronounced "Nyow" ) was a mystery and crime writer from New Zealand. She was born in 1895 and died in 1982. She is widely compared to Agatha Christie. In addition to her mysteries, she was an actress and theater director. Consequently, many of her novels are set in the theatrical world. Her detective, Roderick Alleyn, is a member of the British CID, and is a gentleman. At the beginning of the series, he is forty years old and unmarried. In the sixth novel Artists in Crime, he meets Agatha Troy, an artist. The two later marry and have a son.
Unlike Christie's Poirot or Sherlock Holmes, Alleyn does not have any particular quirks or trademarks. He gets his results by simple dogged police work and intelligence.
Nine of Marsh's novels have been adapted to the small screen.
