Hello Tom,
One of my favourite Doctor Who stories is 'Masque of Mandragora' which was partially filmed in Portmeirion. I have often wondered what became of Norman Jones who played the villainous astrologer, Hieronymous. I really liked his rather sinister performance as leader of the Cult of Demnos. Other than a few cameo appearances in 70's and 80's British tv shows, I haven't seen Norman and I would be interested to know your recollections of him in that particular Doctor Who and whether you know what happened to him.
Regards,
Laurence (Liverpool)
