1881–1950
Born into an aristocratic English family, this Golden Age crime writer brought wit, social insight, and a sharp sense of mystery to her novels. Best known for her detective fiction of the late 1920s and early 1930s, she has since been rediscovered by modern crime readers.

by Molly Thynne
Mary Harriet Thynne, who wrote as Molly Thynne, was a British author born in 1881. She grew up in Kensington and came from a well-connected family; sources also note a family link on her mother’s side to the painter James McNeill Whistler.
Her first novel, An Uncertain Glory, appeared in 1914, but she is best remembered for the run of detective novels she published from 1928 into the early 1930s. Those books place her within the tradition of Golden Age crime fiction, and later reprints have helped bring her work back to new readers.
Biographical sketches describe her as widely traveled, later living in rural Devon, and never marrying. She died in 1950.
