Nobody at Paddington had noticed him among the streams flowing from the arrival platforms, and it was impossible to establish whether or not he had left the station alone. The taxi-driver who had seen him fall had not seen the blow struck, could not even say whether anyone else had been standing on the refuge with him or not. It was a nasty, skiddy evening, and dark at that. He had enough to do to watch the traffic without worrying about people on refuges. It wasn’t until he had seen the poor man stagger into the road almost under his front wheels that he had even noticed him. And then his attention was fully occupied in pulling up and trying to avoid collisions.
