I had just gone to bed after a very hard day when the phone rang. It was an eccentric(怪癖) farmer. I had never met him before although I had heard people talk about him. He sounded quite nervous and talked for a minute or so before I understood anything. Even then all I could make out was that someone called Milly had had a very bad accident. I didn't have the slightest idea who she was but obviously I had to go.

It was snowing heavily that day and I didn't know the way. I had been driving for at least an hour when I finally found his place. He was standing there, waiting for, me. "She meant more to me than anyone... even my own wife!" he said. I could see that he had been crying. I thought something terrible had taken place, a possible scandal(丑闻). I was even more shocked when he told me that he had put her in the barn(厩). "I wouldn't leave her out in the cold!" he said.

Milly had clearly been a secret lover of his. I was about to tell him he could not expect me to cover anything up when he opened the barn door. He lifted his candle and I saw a dark figure on the ground. "She was such a good cow! I wouldn't let anyone but a doctor touch her!" he said, and burst into tears again.
