I really enjoyed the last Dr Who episode: The Crimson Horror. I particularly liked the crazy woman. This turned out to be Diana Rigg. I used to really fancy her when she was in the Avengers. Her main fault was it looked as though she couldn't hit very hard. Of course time is the master of us all, so she could not have remained young and beautiful for ever.
She can still act. She totally deranged in the Dr Who episode.
