Red Harvest by Dashiell Hammett

I dreamed I was sitting on a bench, in Baltimore, facing the tumbling fountain in Harlem Park, beside a woman who wore a veil. I had come there with her. She was somebody I knew well. But I had suddenly forgotten who she was. I couldn't see her face because of the long black veil.

I thought that if I said something to her I would recognize her voice when she answered. But I was very embarrassed and was a long time finding anything to say. Finally I asked her if she knew a man named Carroll T. Harris.
