At this moment, as so often happens in London, there was a complete lull and suspension of traffic. Nothing came down the street; nobody passed. A single leaf detached itself from the plane tree at the end of the street, and in that pause and suspension fell. Somehow it was like a signal falling, a signal pointing to a force in things which one had overlooked. It seemed to point at a river, which flowed past, invisibly, round the corner, down the street, and took people and eddied them along, as the stream at Oxbridge had taken the undergraduate in his boat and the dead leaves. Now it was bringing from one side of the street to the other diagonally a girl in patent leather boots, and then a young man in a maroon overcoat; it was also bringing a taxi-cab; and it brought all three together at a point directly beneath my window; where the taxi stopped; and the girl and the young man stopped; and they got into the taxi; and then the cab glided off as if it were slept on by the current elsewhere.
