The story of the infamous treason plot between General Mathew Arnold and Major André is told in [Major André: Brave Enemy, an] admiring biography of the dashing young British officer-spy. Some detail on Arnold is omitted, and there is a little fictionalization, though no distortion of facts. However, the book is more interesting and smoothly written than the very similar, recent biography by [Adele] Nathan, Major John André … which, though listed as an adult title by the publishers, is not too difficult for good junior high school readers; it has more historical detail, but is far from being comprehensive or scholarly.
