Question: The crime drama that documents that murder of eight people in Notting Hill, London has how many parts?
Context: The Wind of Change is a 1961 British drama, directed by Vernon Sewell and starring Donald Pleasence, Johnny Briggs and Ann Lynn.  Taking its title from the famous "Wind of Change" speech given by British Prime Minister Harold Macmillan in South Africa in February 1960, it is one of the earliest British films to tackle race as an issue, focussing on disenchanted working-class white youth finding an outlet for their frustrations in racial hatred.  The film is set around the coffee bars and homes of the Notting Hill district of West London, scene of the notorious 1958 Notting Hill race riots. John Reginald Halliday Christie (8 April 1899 – 15 July 1953), known to his family and friends as Reg Christie, was an English serial killer active during the 1940s and early 1950s.  He murdered at least eight people – including his wife, Ethel – by strangling them in his flat at 10 Rillington Place, Notting Hill, London.  Christie moved out of Rillington Place during March 1953, and soon afterwards the bodies of three of his victims were discovered hidden in an alcove in the kitchen.  Two further bodies were discovered in the garden, and his wife's body was found beneath the floorboards of the front room.  Christie was arrested and convicted of his wife's murder, for which he was hanged. Ladbroke Grove ( ) is a road in north-west London in the Royal Borough of Kensington and Chelsea, running north–south between Harrow Road and Holland Park Avenue.  It is also a name given to the immediate surrounding area of Notting Hill and North Kensington, straddling the W10 and W11 postal districts. Ladbroke Grove tube station is located on the road, at the point where it is crossed by the Westway.  It is the nearest tube station to Portobello Road Market.  The adjacent bridge and nearby section of the Westway (London) were regenerated in 2007 in a partnership including Urban Eye, Transport for London and London Underground.  Ladbroke Grove is the main road on the route of the annual Notting Hill Carnival.  The northern tip of the road is located in Kensal Green, with the southern end in Notting Hill. George Frederick Tippett (born 1829) was an English builder and entrepreneur who developed much of the former St Quintin Estate in Notting Hill, London.  He is responsible for the construction of many buildings in the area which remain today, including Pinehurst Court, a portered Victorian mansion block at 1-9 Colville Gardens in Notting Hill. Jemima & Johnny (1966) is a British/South African dramatic short film set in London.  It is the first film by South African filmmaker Lionel Ngakane, and won a plate at the 1966 Venice Film Festival.  Just 29 minutes long, the film takes place in Notting Hill, in an environment still affected by the 1958 Notting Hill race riots.  The story concerns two very young children, one, Johnny, the son of a white supremacist, the other, Jemima, the daughter of black Caribbean immigrants, who explore London on their own together, and how their innocent relationship affects the lives of those around them. James Weller Ladbroke (died 16 March 1847) was a nineteenth-century landowner and the principal developer of the Ladbroke Estate, a substantial parcel of land in Notting Hill, London, England.  Many streets in Notting Hill still bear the Ladbroke name today, including Ladbroke Grove and Ladbroke Square, and the former Ladbroke Estate is now a conservation area. Rillington Place is a three-part biographical crime drama about the case of serial killer John Christie, and the wrongful execution of Timothy Evans.  It premiered on 29 November 2016 on BBC One. The Notting Hill Carnival is an annual event that has taken place in London since 1966 on the streets of Notting Hill, in the Royal Borough of Kensington and Chelsea, each August over two days (the August bank holiday Monday and the preceding Sunday).  It is led by members of the British West Indian community, and attracts around one million people annually, making it one of the world's largest street festivals, and a significant event in Black British culture.  In 2006, the UK public voted it onto the list of icons of England.  Despite its name, it is not part of the global Carnival season preceding Lent. Notting Hill is an affluent district in West London, located north of Kensington within the Royal Borough of Kensington & Chelsea.  Notting Hill is known for being a cosmopolitan neighbourhood, hosting the annual Notting Hill Carnival and Portobello Road Market. Pottery Lane is a street in Notting Hill, west London.  Today it forms part of one of London's most fashionable and expensive neighbourhoods, but in the mid-19th century it lay at the heart of a wretched and notorious slum known as the "Potteries and the Piggeries".  The slum came to the attention of Londoners with the building of the Hippodrome in 1837 by entrepreneur John Whyte.  Unfortunately for Whyte a public right of way existed over his land and "dirty and dissolute vagabonds" from the nearby slum invaded his race-course, adding to his financial difficulties and, in part, leading to the closure of his venture in 1842.  Pottery Lane gradually improved in the late 20th century along with the rest of the Notting Hill area, today the houses fetch multi-million pound prices.  Just one of the original brick kilns still survives; it is located in Walmer road, just north of Pottery Lane, and bears a commemorative plaque placed there by the Royal Borough of Kensington and Chelsea.
