St Mary Mead is a quaint, sleepy, fictional village created by the crime fiction writer Dame Agatha Christie. The village is home to the renowned amateur detective Miss Marple. It was first mentioned in a Miss Marple book in 1930, when it was the setting for the first Marple novel, “The Murder at the Vicarage.” Miss Marple lives in Danemead Cottage, the last cottage in Old Pasture Lane. Her telephone number is "three five" on a manual exchange.

St Mary Mead is supposed to be in southern England, 40 kilometres (25 miles) from London and 40 kilometres from Alton. It is just outside the town of Much Benham and is close to Market Basing, which appears in many of Agatha Christie's works. It is not far from the coast, 19 kilometres (12 miles) from the fashionable seaside resort of Danemouth, and also 19 kilometres from the coastal town of Loomouth. Other towns said to be close by include Brackhampton, Medenham Wells, and Milchester. The neighbourhood of St Mary Mead is served by trains arriving at Paddington railway station, indicating a location west or south-west of London. It has been suggested that Market Basing is Basingstoke and Danemouth is Bournemouth. In the BBC “Miss Marple” television adaptations the Hampshire village of Nether Wallop was used as the setting for St Mary Mead. The photograph is of Nether Wallop and the building used to represent Danemead Cottage is on the left of the picture.
