Based on an unsigned journal, this black-and-white graphic novel presents the facts and speculation surrounding this infamous turn-of-the-century murder and media spectacle. Lots of research is pulled together here; fans of true crime will find this brief volume concise yet thorough.
Geary's illustration style is both gothic and contemporary, and works beautifully for his subject. He presents maps, diagrams, portraits and rumor in a simple, yet detailed manner. The gruesome murder scenes are depicted without being overly sensationalized - he couldn't really shy away from it, since actual pictures from the murder scene were widely published at the time and easily obtainable today.
And I like the fact that the unsolved mysteries aren't wrapped up here, either - he offers multiple theories and options, but draws no conclusions for you.
