I read this book when it first came out, thirty-odd years ago, & I was gripped. I have since read many accounts of the life of Gilles de Rais, & I have to say that this is the best one I have read. The background of fifteenth century France is concisely drawn in, the story is told succinctly with no padding & no flinching from unpleasant detail & Benedetti even shows some sympathy for de Rais & the servants who were executed with him. However, the book was written in 1972 &, improbable as it seems, it is a little out of date. Twenty years later, Gilles de Rais was actually re-tried in France &, sensationally, found to be not guilty. Nobody can ever know the truth, but his original trial was highly irregular, de Rais' judges had a financial interest in his destruction, there was never a single body or fragment of a body found in any of his castles & the "confessions" were elicited under torture or the threat of torture. There is a strong likelihood, therefore, that much of this book is actually fiction & morbid fantasy. That said, for the person who has vaguely heard of Gilles de Rais & wants to know more, this is an excellent place to start. One day there will be a revisionist biography of Gilles de Rais in English, as there already is in French, & he may once more be known as an heroic Marshal of France & companion of Joan of Arc. Until then, read this, read between the lines & shudder at the thought that a good man may have been brought low & turned into a monster for all the ages by petty political intriguing.
