"When ‘Harry Leon Crawford’, hotel cleaner of Stanmore was arrested and charged with wife murder he was revealed to be in fact Eugeni Falleni, a woman and mother, who had been passing as a man since 1899. In 1914, as ‘Harry Crawford’, Falleni had married the widow Annie Birkett. Three years later, shortly after she announced to a relative that she had found out ‘something amazing about Harry’, Birkett disappeared."
