I could not sleep that night. I felt that some disaster was going to happen. You know that my sister and I were twins, and twins are very close in a strange way.

It was a stormy night. The wind was blowing outside, and I could hear the rain against the windows. Suddenly, in the middle of the storm, I heard the scream of a woman. It was my sister. I jumped up, put on my dressing gown, and ran out of my room. As I ran, I heard a whistle. I remember it, because it was like the whistle my sister told me about. Then I heard a sound like some metal falling on to the ground.

I ran to my sister's door, and it opened slowly. I was scared. I didn't know what was going to come from her room. By the light in the passage I saw my sister. Her face was white because she was frightened. I ran to her and put my arms around her, and she fell down.
