I heard from John's daughter, Julia, that John had suffered a stroke about 3 weeks ago, and today, I heard from Wilf Crutchley, that John had died. He had this page in Facebook, and the tributes are mounting. His memory will be linked in my mind with fortitude and the letters ZP C separated with a roundel. I regret that the official secrets act prevents disclosure of the investigation of Barking Creek.
BBC One had this story and interview. In any case, a hero is a hero! Thank you, John. For everything.
