M - Maxwell Knight, MI5's Greatest Spymaster
                                
                                
                             
                            
                         
                            
                            
                        Maxwell Knight was a paradox. A jazz obsessive and nature enthusiast, he is seen today as one of MI5's greatest spymasters, a man who did more than any other to break up British fascism during the Second World War - in spite of having once belonged to the British Fascisti himself. This book features his story.
