17 cases of treason digested and excerpted. Mr. Du Cann has a brusque style that relentlessly carves each case down to its essentials. He also has a shrewd eye for those portions of the contemporary trial record which are the most eloquent and embody the significant points of law. His major thesis is that most of England's treason trials were fumbles if not frameups and, secondarily, that the bumbling administration of the treason law has been based on a misinterpretation of the archaic language employed in the 14th century original. Anne Boleyn, Guy Fawkes, St. Thomas More and Sir Walter Raleigh are covered. From the more recent past, there are the questionable cases of Sir Roger Casement and William Joyce. More for the courtroom buff than the expert.
