Tales of the Unexpected 

The man with the white face entered the carriage at Rugby. He moved slowly in spite of the urgency of his porter, and even while he was still on the platform I noted how ill he seemed. He dropped into the corner over against me with a sigh, made an incomplete attempt to arrange his travelling shawl, and became motionless, with his eyes staring vacantly.

He hung silent for a space as if he sought words. ‚Yes, ‚he said, at last, ‚but they tell you nothing.‘
I did not catch his meaning for a second.
‚They don’t know, ‚ he added.
I looked a little more attentively at his face.
‚There are dreams, ‚he said, ‚and dreams.‘
