I wrote about him here after a meeting we had in Periana (Malaga, Spain). Now I found his last adress in this picture published here.
He wrote a book of memoirs, translated to Portuguese, his son Bill helping, that I found at Foyle's, signed. I phone him then just asking if he had been there autographing it. He reply: no!
Later when I met him he signed again «spies like us», joking!
