from isolated individuals such as the late anthropologist and conservationist Richard Leakey, F.R.S., Kenyan white people have virtually completely retreated from Kenyan politics, and are no longer represented in public service and parastatals, from which the last remaining staff from colonial times retired in the 1970s. The book and movie White Mischief included an earlier member of the Cholmondeley family, The 4th Baron Delamere (popularly known as Tom Delamere). He was married to Diana Broughton, a member of the Happy Valley set, whose lover was murdered in Nairobi in 1941. Her first husband, Jock Delves Broughton, was tried and acquitted. The 2005 homicide case of game ranger Samson ole Sisina by the white Kenyan dairy and livestock farmer and game rancher, the Hon. Thomas Cholmondeley, a descendant of British aristocrats, has brought into question the class bias of the judicial system of the Commonwealth country and the resentment of many Kenyans toward what they perceive as white privilege.

From the 1930s the group became infamous for its decadent lifestyles and exploits following reports of drug use and sexual promiscuity. The area around Naivasha was one of the first to be settled in Kenya by white people and was one of the main hunting grounds of the 'set'. The colonial town of Nyeri, Kenya, to the east of the Aberdare Range, was the centre of Happy Valley settlers. The white community in Kenya in the years before the Second World War was divided into two distinct factions: settlers, on the one side, and colonial officials and tradesmen, on the other. Both were dominated by upper-middle-class and upper-class British and Irish (chiefly Anglo-Irish) people, but the two groups often disagreed on important matters ranging from land allocation to how to deal with the indigenous population. Typically, the officials and tradesmen looked on the Happy Valley set with embarrassment. The height of the Happy Valley set's influence was in the late 1920s. The recession sparked by the 1929 Wall Street stock market crash greatly decreased the number of new arrivals to the Colony of Kenya and the influx of capital. Nevertheless,
