If you are looking for some light entertainment, this book might fill the bill. This is a fast moving, action packed adventure. It features heroic, handsome, brilliant, fearless smarty-pants barrister-amateur detective Reginald Brett. (Tracy assures us that Brett is the greatest amateur detective of his generation.) The book moves along at a quick pace as Brett and his friends chase diamond thieves in Europe. This is not a great mystery, or a great book in any sense, but it is fun. And, by the end of the book I found I kind of liked Reginald Brett - in spite of myself.
