I've just remembered another time when perhaps I did see a ghost. I can't think of another way to explain it.
I was 17 or 18 and on my way to visit friends in London's East End. It was a bright sunny evening so I took a short cut along a very long and narrow cobbled passageway, which I often did. I probably wouldn't do that today, but I was young and thought I could look after myself. The passage was only one person wide and on both sides were the high walls of factories, warehouses and tenements, so nowhere for anyone to hide or jump out on me. I was about half way along and could see the other end in the distance when a man suddenly appeared ahead of me hurrying towards me. Where had he come from he hadn't been there a moment ago? He was dressed all in black, his long coat flying out around him, carrying a stick or something and wearing, to my amazement, a top hat. I was startled and immediately realised I'd have to pin myself to the wall to let him pass or be knocked over. It didn't look like he was going to stop! Then as he got closer he did stop, looked to his left, turned left and walked away! I couldn't believe it. I was pretty certain there were no other exits out of the passage except at each end. I walked on to the place where he had left and there was nothing there, just the high brick wall of a factory. No doors or gates and the windows were on the first floor. Where had he gone? I looked around me but there was no way out of that passage, unless he could walk through walls. I hurried on but kept glancing back to see if he was behind me. When I got to my friend's I told them and they said "Yes other people have seen him too. Some people think it's Jack the Ripper." Who or what did I see? But it didn't stop me going that way again. But I never saw him again.
