I was walking along the main street of a small seaside town in the north of England looking for somewhere to make a phone call.My car had broken down outside the town and I wanted to contact the AA Company.Low grey clouds were gathering across the sky and there was a cold damp wind blowing off the sea which nearly threw me off my feet every time I crossed one of the side streets.It had rained in the night and water was dropping from the bare trees that lined the street.I was glad that I was wearing a thick coat.

There was no sign of a call box, nor was there anyone at that early hour whom I could ask.I had thought I might find a shop open selling the Sunday papers or a milkman doing his rounds, but the town was completely dead.The only living thing I saw was a thin frightened cat outside a small restaurant.

Then suddenly I found what I was looking for.There was a small post office, and almost hidden from sight in a dark narrow street.Next to it was the town’s only public call box, which badly needed a coat of paint.I hurried forward, but stopped in astonishment when I saw through the dirty glass that there was a man inside.He was fat, and was wearing a cheap blue plastic raincoat.I could not see his face and he didn’t raise his head at the sound of my footsteps.

Carefully, I remained standing a few feet away and lit a cigarette to wait for my turn.It was when I threw the dead match on the ground that I noticed something bright red trickling from under the box call door.
