Lady Cynthia Mary Evelyn Asquith (27 September 1887 – 31 March 1960) was an English writer and socialite, now known for her ghost stories and diaries.  She also wrote novels and edited a number of anthologies, as well as writing for children and on the British Royal family.
Life and career
In 1913 she met D. H. Lawrence in Margate, and became a friend and correspondent. She took a position as secretary to Peter Pan creator J. M. Barrie, with whom she became close friends, continuing to work for him until his death in 1937. Barrie left the bulk of his estate – minus the Peter Pan works – to her. The author L. P. Hartley became a lifelong friend after they met in the early 1920s.
One of Asquith's stories, "The Follower", was adapted for BBC Radio, along with stories by Algernon Blackwood, Marjorie Bowen and Noel Streatfeild; all these stories were later reprinted in the Cecil Madden anthology My Grimmest Nightmare (1935).
