I found out after reading this book that the case was quite famous, though I had never heard of it before. It's one of those curious situations, in which you can't quite believe that the main suspect did it, and you can't quite believe that she didn't. For once 'Not Proven' seems an apt judgment, and after you read this book I think you will agree.
This book is well written and exhaustively researched; it basically presents the evidence in full and allows the reader to judge for him/herself. I found it quite refreshing in a world in which non-fiction authors are expected to 'slant' material in order to excite a jaded audience. Douglas MacGowan is to be commended for being straightforward and unbiased.
