“Ninja: Unmasking the Myth is a brave book. With a scientific sense of objectivity, Turnbull tears down an edifice that he himself helped to build, shining the harsh glare of academic rigour on his earlier work. In doing so, he uncovers some striking facts about the evolution of the ninja, not the least that the word doesn’t even occur in Japanese-English dictionaries until 1974.”
My review of Stephen Turnbull’s demolition (and reconstruction) of ninja in history, up now on the All the Anime blog.
