Jack the Ripper

In the autumn of 1888, at least five women were murdered in the Whitechapel district of London with a level of surgical precision that suggested medical knowledge. "Jack the Ripper" — named after a letter sent to a news agency (likely a hoax) — was never caught. The case has generated over 100 suspects in academic literature, including a royal physician, a Polish immigrant, and Lewis Carroll. DNA evidence in 2019 pointed to Aaron Kosminski, a Polish barber, but the methodology was challenged by geneticists. 137 years later, the case remains open. More books have been written about the Ripper than any other criminal in history.
