In the graphic novel From Hell, which historical London murderer is investigated?

In the graphic novel From Hell, the historical murderer investigated is Jack the Ripper.

From Hell was written by Alan Moore and illustrated by Eddie Campbell. Published in serialized form before being collected as a graphic novel, it explores the Whitechapel murders of 1888 and the social conditions of Victorian London. The story uses the killings as the basis for a broad historical and psychological narrative.

The book focuses especially on the theory that Sir William Gull, a royal physician, was responsible for the murders. That theory is fictionalized and remains historically disputed; Jack the Ripper’s identity has never been conclusively established. The graphic novel therefore should not be treated as a definitive solution to the case.

Moore and Campbell also include extensive historical notes. These notes distinguish documented events from speculation and explain where the creators altered chronology, dialogue, or characters for dramatic purposes. The title comes from the famous “From Hell” letter associated with the case, although the letter’s authenticity is also debated.
