Treatise on Poisons

Long before CSI labs and toxicology screens, a Scottish physician set out to catalog the body's quiet assassins. Robert Christison's monumental work, born in the age of Sherlock Holmes and arsenic wallpaper, was the first systematic treatise on poisons written in English, part forensic manual, part pharmacological thriller. He dissected poisonings from every angle: the murderer in the drawing room, the wife slipping arsenic into her husband's tea, the factory worker succumbing to lead. Christison wasn't merely cataloging death; he was building the architecture of forensic toxicology, arming physicians with the tools to detect the undetectable and bring killers to justice in an era when 'prussian blue' was the only test for arsenic. This text laid the scientific groundwork for every crime scene investigation that would follow.
