Some monsters are figments of our imagination. Others are as real as flesh and blood: humans who may look like us, who may walk among us, often unnoticed, occasionally even admired-but whose evil deeds and secret lives, once revealed, mark them as something utterly wicked. In this illustrated volume from Aaron Mahnke, the host of the hit podcast Lore, you'll find tales of infamous characters whose veins ran with ice water and whose crimes remind us that truth can be more terrifying than fiction. Mahnke introduces us to William Brodie, a renowned Scottish cabinetmaker who used his professional expertise to prey on the citizens of Edinburgh and whose rampant criminality behind a veneer of social respectability inspired Robert Louis Stevenson's classic novella Strange Case of Dr.Jekyll and Mr. Hyde. Then there's H. H. Holmes, a relentless and elusive con artist who became best known as the terror of Chicago's 1893 World's Fair, where unwitting guests were welcomed into his "hotel" of horrors... never to be seen again. And no rogues' gallery could leave out Bela Kiss, the Hungarian tinsmith with a taste for the occult and a collection of gasoline drums with women's bodies inside. Brimming with accounts of history's most heinous real-life fiends, this riveting best-of-the-worst roundup will haunt your thoughts, chill your bones, and leave you wondering if there are mortal monsters lurking even closer than you think.
