Fiendish, evil, demonic, hellish - every one of these adjectives applies to the diabolical acts that the people in this book have committed. Killers such as Vlad the Impaler (the real-life Dracula), who is far more threatening and sadistic than Bram Stoker's fictional vampire. Burke and Hare, possibly two of Scotland's most gruesome inhabitants, who murdered people so that they could sell the cadavers. Albert Fish, a man so fiendish that his story makes Hannibal Lecter's exploits seem tame by comparison. You can read about these and many more who commit unspeakable crimes with complete disregard for their fellow human beings.
