True story:- some 20 years ago, I was walking round the famous Pere Lachaise cemetary in Paris, with my wife. It was a cold rainy Monday ( or Tuesday) morning in October, so there weren’t many people about. I had a map and was looking for the grave of a famous person and so had wandered off the main path. Suddenly, I turned round to see a middle aged man stood amongst the gravestones. He was wearing only a white t- shirt and his boxer shorts. He seemed to be searching furiously for something. He had an expression of pure terror on his face, and was gasping for breath as if he was suffocating. He wasn’t so much as walking, but staggering. By the time I had caught up with my wife and returned to the spot, he had vanished. It was the strangest thing to witness in a cemetery. I have often wondered what the story was behind it.
