London police never solved the Ripper mystery and never made a major arrest, although many suspects were named. The case destroyed Sir Charles Warren's career as police commissioner and sparked a massive social reform movement to alleviate the appalling conditions of poverty in which the Ripper's victims—and more than a million other souls—lived. The following spring, James Maybrick died of acute arsenic poisoning. His complicity in the Ripper case did not come to light for another century. His innocent American widow, her unfortunate affair with Mr. Brierly having come to public notice, was convicted of murder—largely because of her adultery—in a trial that shocked all of England and sparked a decade and a half of protests from the American State Department. Florie Maybrick served fifteen years in prison, then returned to the United States and lived in quiet anonymity under an assumed name, never realizing she had lived in the house that Jack built.
