I saw this when it was aired in 1987 and have never forgotten it - we couldn't wait for the next episode! It was mesmerising, and Nigel Havers was truly creepily thrilling as the handsome cad who gets himself deeper and deeper into trouble. I can never forget the final image; I won't spoil it in case they ever do show it again, but it is beautifully handled. You feel satisfaction, pity, compassion and a sense of justice. Bernard Hepton was even more creepy as the outwardly mild-mannered man out for revenge. I would love to see it again, still hoping for a DVD. I've always liked Rosemary Leach, her performance is great as well. I don't know why comments now have to be 10 lines - they never used to be. Why write more than you have to?
