    As I jogged over the bridge and round the corner on my regular early morning run, he was standing opposite the jeweler’s, looking extremely suspicious. But the moment he saw me, instead of trying to avoid me, he came straight across the road as I drew level with the jeweler’s. Halfway across he began addressing me: “I thought you were going to…” — but his voice trailed away as he received no reply and no sign of recognition from me. It was quite obvious that he had mistaken me for someone else. But he started up again as if nothing had happened．“Good morning, ” he said．“Nice to bump into someone so early. Someone to talk to. I’ve taken to talking to myself on this job.”

I hate meeting people when I’m out early, and I was almost out of breath, so I just paused in my stride, nodded in a friendly manner, and went on up the road. The stranger had spoken quietly, and quite slowly. And I had noticed that he was well dressed, too. But if he looked suspicious dressed like that at that time of the morning, what about me? I was in a track suit, with an old sweater round my shoulders and a cap on my head．As to his odd remark about “talking to himself on this job”, I hadn’t paid any attention to it, although now it began to worry me. Was he perhaps a plain clothes policeman? At the time I somehow felt he was.

I had just turned the corner into the High Street when I heard the sound of breaking glass somewhere behind me, and I thought the sound came from the street I had just left. I stopped dead and almost without thinking looked back around the corner. The stranger was not there, but almost immediately an alarm bell in the jeweler’s began ringing furiously.

I found out later that a burglar had broken into the jeweler’s shop and stolen watches and rings worth about  ￡5,000. The police are still looking into the matter, but I’m afraid to go and tell them what I know now because they might even suspect me of committing the crime, and it might be difficult for me to prove my innocence. After all, I haven’t offered my assistance as a witness, and the only other person around that morning was the “stranger” who had spoken to me.
