A is for Arsenic: The Poisons of Agatha Christie ... has lethal charm. [Kathryn] Harkup leads every chapter with a literary quote, then proceeds to tell us what the poison is, how and under what circumstances it kills, some real-life instances of its use and what role it plays in the Christie plot ... good fun.

...a knockout analysis of poisons used in Christie's novels and short stories...Each chapter gives riveting information on the poison's chemical makeup, how it kills, whether there's an antidote, its history and its use in Christie's works and in real life...This is an absolutely bravura chemical compound.
