The couple was hanged together in November 1849 and the public execution was attended by Charles Dickens, who wrote of the event, "I believe that a sight so inconceivably awful as the wickedness and levity of the immense crowd collected at that execution this morning could be imagined by no man, and could be presented in no heathen land under the sun." He would later base the Bleak House character Mademoiselle Hortense on Maria.
