The Marguerite Steinheil case, 1909.

The Marguerite Steinheil case, 1909. Marguerite Steinheil (1869-1954) became famous for her connection with the death in 1899 of President Felix Faure of France, whose mistress she had been. In 1908, Marguerite's stepmother and her husband were found murdered in their Paris home. Marguerite was found gagged and tied to a bed and claimed that she had been tied up by four intruders. The police suspected Marguerite of the murder, and she was arrested in November. The following year, after a sensational trial, she was acquitted. She then moved to London, writing her memoirs in 1912. A print from L'Illustration, 13 November 1909. (Photo by The Print Collector/Print Collector/Getty Images)
