Venenos Literarios

Poisons are silent protagonists in Agatha Christie's novels, lethal substances that unleash perfect mysteries with baffling symptoms and deaths that challenge both detectives and readers. A minimal dose was enough to weave masterful plots where toxicology became the ultimate narrative weapon. Kathryn Harkup, chemist and science writer, takes us into this fascinating universe where science and crime meet. Through fourteen captivating chapters, she examines the poisonous substances Christie used in her most famous works, revealing their chemical composition, the devastating effects they have on the body, and their role in real crimes throughout history. Each poison comes to life in these pages: from cyanide to strychnine, the availability of these substances in the first half of the 20th century to methods of forensic detection. The author reveals real criminal cases that inspired Agatha Christie and demonstrates how she not only mastered the art of suspense, but also the scientific fundamentals that lent credibility to her most elaborate enigmas. History, science, and literature are masterfully intertwined in a story that reveals how toxicology, far from being a mere narrative device, became the key to the realism and tension of the plots of the queen of crime.
