Seven Dials is a small but well-known road junction in the West End of London in Covent Garden where seven streets converge. At the centre of the roughly-circular space is a pillar bearing six (not seven) sundials, a result of the pillar being commissioned before a late stage alteration of the plans from an original six roads.

The term also refers informally to the immediate surrounding area.

The landed estate belongs to the Worshipful Company of Mercers which allowed building licences on what was open farmland to maximise their income in what was the burgeoning West End of the developing metropolitan area. The original layout of the Seven Dials area was designed by Thomas Neale in the early 1690s. The original plan had six roads converging, although this was later increased to seven. The sundial pillar was built with only six faces, however, probably because of the original design. This number of roads was chosen in order to maximise the number of houses that could be built on the site.

Following the successful development of the fashionable Covent Garden Piazza area nearby, Neale aimed for the Seven Dials site to be popular with well-off residents. This was not to be, however, and the area gradually deteriorated. At one stage, each of the seven apexes facing the column housed a pub. By the nineteenth century, Seven Dials had become one of the most notorious slums in London, being part of the rookery of St Giles. The area was described colourfully by Charles Dickens in his collection Sketches by Boz, which includes the quote:

Dame Agatha Mary Clarissa Christie DBE (née Miller; 15 September 1890 – 12 January 1976) was a British crime writer of novels, short stories, and plays. She also wrote romances under the name Mary Westmacott, but she is best remembered for her 66 detective novels and more than 15 short story collections (especially those featuring Hercule Poirot or Miss Jane Marple), and her successful West End plays.

According to the Guinness Book of World Records, Christie is the best-selling novelist of all time. Her novels have sold roughly four billion copies, and her estate claims that her works rank third, after those of William Shakespeare and the Bible, as the most widely published books. According to Index Translationum, Christie is the most translated individual author, with only the collective corporate works of Walt Disney Productions surpassing her. Her books have been translated into at least 103 languages.

Agatha Christie published two autobiographies: a posthumous one covering childhood to old age; and another chronicling several seasons of archaeological excavation in Syria and Iraq with her second husband, archaeologist Max Mallowan. The latter was published in 1946 with the title, Come, Tell Me How You Live.
