One person thought Lewis Carroll was accused of being Jack the Ripper.

Lewis Carroll, born Charles Lutwidge Dodgson, is the author of Alice's Adventures in Wonderland, a mathematician, and a posthumous suspect in the Jack the Ripper murders.

For over a century, crime buffs have been perplexed by the unsolved murder and disembowelment of several sex workers in London's Whitechapel neighborhood in 1888. However, in 1996, author Richard Wallace published a very different theory: that Lewis Carroll, who was so mild-mannered that he frequently wrote home from boarding school to complain about his classmates being a little too loud, was responsible for the Ripper murders with the help of his friend Thomas Vere Bayne. The premise of Wallace's full-length book, Jack the Ripper, Light-Hearted Friend, was this.

This theory didn't make much sense: Carroll lived near the murder sites, but during the time when four victims were killed, he was on vacation in East Sussex, and Bayne was unable to move due to back pain. Carroll's handwriting also didn't match the Ripper's letters to newspapers, which Wallace attributed to Bayne.

The main reason Wallace suspected Carroll was due to... anagrams. Carroll enjoyed wordplay and anagrams, so Wallace rearranged text from his letters and published works to uncover hidden Jack the Ripper messages.
