Career
He was head of the stables of the future King Edward VII (then Prince of Wales) and a Major in the Royal Horse Guards. He was linked with the Cleveland Street scandal, wherein he was identified and named by several male prostitutes as a customer of their services. He was interviewed by police on 7 August 1889.
Although the record of the interview has not survived, it resulted in a report being made by the Attorney-General, Solicitor-General and Director of Prosecutions urging that proceedings should be taken against him under section 11 of the Criminal Law Amendment Acting 1885.
A piece of paper was pasted over Somerset"s name in the report, as it was deemed so sensitive. However, the Director was told that the Home Secretary wished him to take no action for the moment.
The police obtained a further statement implicating Somerset, while Somerset arranged for his solicitor to act in the defence of the boys arrested over the scandal. After the police saw him for a second time on 22 August, Somerset obtained leave from his regiment and permission to go abroad.
Lord Arthur went to Homburg, although he returned to England.
When tipped off in September that charges were imminent, he fled to France to avoid them. From there he travelled through Constantinople, Budapest, Vienna, and then back to France, where he settled and died in 1926, aged 74.
