221B Baker Street is the London address of the fictional detective Sherlock Holmes, created by author Sir Arthur Conan Doyle. In the United Kingdom, postal addresses with a number followed by a letter may indicate a separate address within a larger, often residential building. Baker Street in the late 19th century was a high-class residential district, and Holmes's apartment would probably have been part of a Georgian terrace. The residence was introduced in the novel A Study in Scarlet (1887). At the time the Holmes stories were published, addresses in Baker Street did not go as high as 221. Baker Street was later extended, and in 1932 the Abbey National Building Society moved into premises at 219–229 Baker Street. For many years, Abbey National employed a full-time secretary to answer mail addressed to Sherlock Holmes. In 1990, a blue plaque signifying 221B Baker Street was installed at the Sherlock Holmes Museum, situated elsewhere on the same block, and there followed a 15-year dispute between Abbey National and the Holmes Museum for the right to receive mail addressed to 221B Baker Street. Since the closure of Abbey House in 2005, ownership of the address by the Holmes Museum has not been challenged, despite its location between 237 and 241 Baker Street. Its postal code is NW1 6XE.

The Baker Street robbery was the burglary of safety deposit boxes at the Baker Street branch of Lloyds Bank in London, on the night of 11 September 1971. A gang tunnelled 40 feet (12 m) from a rented shop two doors away to come up through the floor of the vault. The value of the property stolen is unknown, but is likely to have been between £1.25 and £3 million; only £231,000 was recovered by the police.The burglary was planned by Anthony Gavin, a career criminal, who was inspired by "The Red-Headed League", a short story by Arthur Conan Doyle in which Sherlock Holmes waits in a bank vault to arrest a gang who have tunnelled in through the floor. Gavin and his colleagues rented Le Sac, a leather goods shop two doors from the bank, and tunnelled during weekends. The interior of the vault was mapped out by one gang member using an umbrella and the span of his arms to measure the dimensions and location of the furniture. The gang initially tried to use a jack to force a hole in the vault floor and when this failed they used a thermal lance. When this also failed to work, they used gelignite to blast a way through. Once inside, they emptied 268 safety deposit boxes. The gang had posted a lookout on a nearby roof, who was in contact via walkie-talkie, and their broadcasts were accidentally overheard by Robert Rowlands, an amateur radio enthusiast. He called the police, who initially did not take him seriously, so he used a small cassette recorder to make a recording of the burglars' conversations. The second time he contacted the police they accepted what he was saying, and began hunting for the burglars while the break-in was in progress. They searched 750 banks in an 8-mile (13 km) radius, but failed to locate the gang. Police found the members of the gang soon after the break-in; one of the burglars, Benjamin Wolfe, had signed the lease for Le Sac in his own name and informers provided information that led to Gavin. At the end of October 1971 police arrested Wolfe, Gavin, Reg Tucker and Thomas Stephens. They continued to search for other members of the gang, including one woman, for five years, but no further arrests were made. Gavin, Tucker and Stephens were sentenced to twelve years in prison; Wolfe received a sentence of eight years, less than the others as he was in his 60s. There have been several rumours connected with the burglary, including one that the government issued a D-Notice to censor the press; that one of the safety deposit boxes contained compromising photographs of Princess Margaret and the actor and criminal John Bindon; and that photographs of a Conservative cabinet minister abusing children were found. There is no evidence to support these claims and they have been widely dismissed. Some of the rumours inspired the story for the 2008 film The Bank Job. Many of the papers relating to the burglary remain under embargo at The National Archives until January 2071.

The Metropolitan Borough of St Marylebone was a metropolitan borough of the County of London from 1900 to 1965. It was based directly on the previously existing civil parish of St Marylebone, which was incorporated into the Metropolitan Board of Works area in 1855, retaining a parish vestry, and then became part of the County of London in 1889. It was that part of the current City of Westminster which is north of Oxford Street, and east of Maida Vale and Edgware Road. It included the areas Marylebone, Regent's Park, St John's Wood, and Lisson Grove, along with the western part of the district of Fitzrovia. In 1965 it was abolished and its former area was amalgamated with that of the Metropolitan Borough of Paddington and the Metropolitan Borough of Westminster to form the City of Westminster.
