A new British TV Series, called Royal Murder Series, will feature the murder of Jossyln Hay aka Lord Erroll, the 22nd Earl of Erroll. The murder was infamously called the Happy Valley murder.

The Royal Murder Series is a historical account of six people who are royalty and were caught up in murder cases.

Jossyln Hay, who was found dead in his car in 1941, was part of a group of colonials who lived in Kenya known as the ‘Happy Valley Set’. They were know to throw lavish parties that would go on for three days in a row and sometimes ended in sexual orgies. Josslyn Hay, who was probably the most famous among this group, is believed to have been murdered by Sir Henry ‘Jock’ Delves Broughton, whose wife, Diana Broughton was having an affair with him, though the murder has never been solved. Seven theories have put forward as to who might have been the murderer and they list Diana Broughton as one of the suspects based on the fact that she was the last to see Jossyln Hay alive and that she was upset that he had refused to marry her.

The bizarre lifestyle of the Happy Valley clan was at one point made into a movie called White Mischief which starred Charles Dance and Greta Scacchi.

The episode aired yesterday on UKTV’s Yesterday Channel at 8pm UK time. You can watch it online here.
