But none of these writers, I think, did more justice to that most famous of homicidal poisons, arsenic, than did Sayers in Strong Poison. The title comes from the lyrics of a 17th century ballad, The Poisoned Man: “O that was strong poison, my handsome young man/O yes, I am poisoned mother; make my bed soon/For I’m sick to the heart, and I fain wad lie down.” But the chemistry is absolutely up-to-date for 1930, the year the book was published. In fact, Sayers for all her literary background (she was an Oxford University educated scholar of classical languages and considered her translation of Dante’s Divine Comedy to be her best work) performs as an outstandingly good science writer in the course of the story.
