I realise this is a long shot - it's been three years since your post - but I have just come across your comment in my research for writing the story of Jago Stone and his times. If you would like to email me at firstname.lastname@example.org, I would be delighted to hear more about Jago. My wife and her mother and father knew Jago between 1968 and 1970 and we have several of his oils and water-colours. 'The Burglar's Bedside Companion' is a fine book, witty and wise. It is a compelling indictment of penal policy and its failings. And it provides a well-written insight into an attractive character who explicitly identifies with Don Quixote and his need to tilt at the windmills of convention.
