For centuries, people have been poisoning one another—changing personal lives and the course of empires alike. From spurned spouses and rivals, to condemned prisoners like Socrates, to endangered emperors like Alexander the Great, to modern-day leaders like Joseph Stalin and Yasser Arafat, poison has played a starring role in the demise of countless individuals. And those are just the deliberate poisonings. Medical mishaps, greedy "snake oil" salesmen and food contaminants, poisonous Prohibition, and industrial toxins also impacted millions. Part history, part chemistry, part whodunit, Poison: Deadly Deeds, Perilous Professions, and Murderous Medicines traces the role that poisons have played in history from antiquity to the present and shines a ghoulish light on the deadly intersection of human nature...and Mother Nature.
