In 1891, an unknown criminal began poisoning women in London

In 1891, a mysterious figure appeared on the streets of London, dispensing pills to poor young women who then died in agony. Suspicion came to center on a Scottish-Canadian doctor with a dark past in North America. In this week's episode of the Futility Closet podcast we'll describe the career of the Lambeth Poisoner, whose victims remain uncounted.

We'll also consider a Hungarian Jules Verne and puzzle over an ambiguous sentence.
