The book uncovers the involvement of the Secret Service and how Maundy Gregory exploited sensitive information that enabled him to gain access and influence to pillars of the establishment. It reveals for the first time the contents of the recently de-classified secret file held on Gregory and his activities by the Vatican and exposes the circumstances surrounding Gregory's 1933 arrest for selling honours and the deal he was offered by Cabinet Ministers to quit the country in return for a light sentence and a pension for life.
