Scotland Yard (officially New Scotland Yard) is a metonym for the headquarters of the Metropolitan Police Service (MPS), the territorial police force responsible for policing most of London.
Charles Frederick Field (1805–1874) was a British police officer with Scotland Yard and, following his retirement, a private detective.
 Field is perhaps best known as the basis for Inspector Bucket in Charles Dickens's novel "Bleak House".
New Scotland Yard is a police drama series produced by London Weekend Television (LWT) for the ITV network between 1972 and 1974.
 It features the activities of two officers from the Criminal Investigations Department (CID) in the Metropolitan Police force headquarters at New Scotland Yard, as they dealt with the assorted villains of the day.
The Black Museum, or The Crime Museum of Scotland Yard, is a collection of criminal memorabilia kept at New Scotland Yard, headquarters of the Metropolitan Police Service in London, England.
 The museum came into existence sometime in 1874, although unofficially.
 It was housed at Scotland Yard, and grew from the collection of prisoners' property gathered under the authority of the Prisoners Property Act of 1869.
 The act was intended to help the police in their study of crime and criminals.
 By 1875, it had become an official museum, although not open to the public, with a police inspector and a police constable assigned to official duty there.
Robert Honey Fabian (31 January 1901 – 14 June 1978) was an English police officer, who rose to the rank of Detective Superintendent in the Metropolitan Police.
 After retirement from the force, he worked as crime writer.
 His work was dramatised in the BBC drama series, "Fabian of the Yard", based on his book of the same name (in reference to New Scotland Yard).
 Each episode ended with an epilogue in which Fabian described the real-life case on which the preceding story had been based.
 He subsequently wrote a somewhat salacious but revelatory account of Soho's vice trade in "London After Dark".

Whitehall 1212 was the famous telephone number of Scotland Yard.
 It was introduced in 1934 and was used by the public to contact the London Metropolitan Police information room for both emergency and non-emergency business.
 With the introduction of the 999 number for emergencies in 1937, "Whitehall 1212" (dialled as "WHI 1212") remained in use for non-emergencies until the 1960s and the introduction of all-figure numbering.
 Today the switchboard number for New Scotland Yard is "020 7230 1212", and the last four digits of the telephone number for several other Metropolitan police buildings are "1212".
Bertha Clayden was a British police officer.
 After the London Metropolitan Police's women police were reorganised in 1922 and most were dismissed, Clayden was put in charge of the twenty who remained, becoming the first attested female officer to hold the rank of Inspector.
 When Dorothy Peto was appointed Superintendent in charge of women police in 1930, Clayden remained as Woman Inspector at Bow Street.
 On 30 April 1934 she was promoted to Sub-Divisional Inspector, the first (and possibly only) woman to hold that rank, and became deputy to Peto at Scotland Yard.
 She seems to have eventually reached the rank of Chief Inspector.
 A motherly woman, her officers considered her to be far more approachable than the austere Peto.
Scotland Yard vs. Dr Mabuse (German: Scotland Yard jagt Dr. Mabuse , also known as "Scotland Yard Hunts Dr. Mabuse") is a 1963 German crime film directed by Paul May and starring Peter van Eyck.
Scotland Yard is a board game in which a team of players, as police, cooperate to track down a player controlling a criminal around a board representing the streets of London.
 It is named after Scotland Yard, the headquarters of London's Metropolitan Police Service.
 "Scotland Yard" is an asymmetric board game, with the detective players cooperatively solving a variant of the pursuit-evasion problem.
 The game is published by Ravensburger in most of Europe and Canada and by Milton Bradley in the United States.
 It received the "Spiel des Jahres" (Game of the Year) award in 1983.
Bleak House is the ninth novel by English author Charles Dickens, first published as a serial between March 1852 and September 1853.
 The novel has many characters and several sub-plots, and the story is told partly by the novel's heroine, Esther Summerson, and partly by an omniscient narrator.
 At the centre of "Bleak House" is a long-running legal case, "Jarndyce and Jarndyce", which came about because someone wrote several conflicting wills.
 Dickens uses this case to satirise the English judicial system.
 Though the legal profession criticised Dickens's satire as exaggerated, this novel helped support a judicial reform movement, which culminated in the enactment of legal reform in the 1870s.
