Claim: Billie Carleton, an English musical comedy actress, died of an apparent overdose of cocaine after attending the Victory Ball at the Royal Albert Hall in 1918.
Evidence: Billie Carleton (4 September 1896 – 28 November 1918) was an English musical comedy actress during the First World War. On 27 November 1918, she left the theatre after performing, and, wearing a daringly diaphanous outfit designed by her friend Reggie de Veulle, attended the Victory Ball at the Royal Albert Hall. The next day Carleton's maid found her dead in bed in her Savoy Hotel suite, apparently killed by an overdose of cocaine.
