Miss Marple is a fictional character in Agatha Christie's crime novels and short stories. Jane Marple lives in the village of St. Mary Mead and acts as an amateur consulting detective. Often characterized as an elderly spinster, she is one of Christie's best-known characters and has been portrayed numerous times on screen. Her first appearance was in a short story published in The Royal Magazine in December 1927, "The Tuesday Night Club", which later became the first chapter of The Thirteen Problems (1932). Her first appearance in a full-length novel was in The Murder at the Vicarage in 1930, and her last appearance was in Sleeping Murder in 1976.
The character of Miss Marple is based on friends of Christie's step grandmother/aunt (Margaret Miller, née West). Christie attributed the inspiration for the character to a number of sources, stating that Miss Marple was "the sort of old lady who would have been rather like some of my step grandmother's Ealing cronies – old ladies whom I have met in so many villages where I have gone to stay as a girl". Christie also used material from her fictional creation, spinster Caroline Sheppard, who appeared in The Murder of Roger Ackroyd. When Michael Morton adapted the novel for the stage, he replaced the character of Caroline with a young girl. This change saddened Christie and she determined to give old maids a voice: Miss Marple was born.
Christie may have taken the name from Marple railway station, through which she passed, or from Marple Hall, near her sister Margaret Watts' home at Abney Hall.
