A couple of years back I was in York, watching the York Mystery Plays - a superb bit of biblical storytelling that's been coming to York every four years for centuries. About 15 minutes after the start, an american voice behind me said to her companion "This is definitely not Agatha Christie!", and the two of them got up and left. I'm afraid I sniggered for the whole of the rest of the performance.

Cheers
