A lot of glass waxing of the dusty, dirty windows of history when police procedure is applied to past crimes. The prickles of boredom vanish when hospitalized ant of Scotland Yard digs deep into the story of Richard III and the little princes the Tower and comes up with some reversed judgements on accepted facts. Helped by enthusiastic young American researcher, Grant discards the tame historians of the dor era, goes back into contemporary accounts and pieces together bits and pieces of York, Plantagenet, Lancaster and Tudor personalities and events to form a very different sort of picture. Bright investigation of the sharper practices of the 15th century, this is for the higher-browed sleuth fanciers.
