Peter Shand Kydd was half-brother to the brother-in-law of a British peer suspected of murder who disappeared in what year?
Peter Shand Kydd Peter Shand Kydd (23 April 1925 – 23 March 2006) was the former stepfather of Diana, Princess of Wales, and an heir to the wallpaper fortune built by his father Norman Shand Kydd (1895–1962). His mother was Francis Madalein Foy (died 1983). He was half-brother to the former champion amateur jockey William Shand Kydd (1937–2014), who was brother-in-law of John Bingham, 7th Earl of Lucan.
Death of Gareth Williams Gareth Williams (26 September 1978 –  16 August 2010 ) was a Welsh mathematician and employee of GCHQ seconded to the Secret Intelligence Service (SIS or MI6) who was found dead in suspicious circumstances at a Security Service safe house flat in Pimlico, London, on 23 August 2010. The inquest found that his death was "unnatural and likely to have been criminally mediated." A subsequent Metropolitan Police re-investigation concluded that Williams's death was "probably an accident". It is also suspected that he should be numbered amongst those who have been killed by Russian assassins on British soil. Two senior British police sources have said some of Williams's work was focused on Russia – and one confirmed reports that he had been helping the NSA trace international money-laundering routes that are used by organised crime groups including Moscow-based mafia cells.
