Almost simultaneously with the beginning of the music the moon, like a piece of carved silver floating through the winter sky, attended by a little drift of fluffy amber and sulphur-coloured clouds, swung round from behind New College tower, sending a broad band of green light across the room.

Sturtevant's white face was thrown into sharp relief against the shadow.

Condamine sat quite still, shivering a little. He felt cold. The strange music tinkled on, like the overture to some strange experience, sounding almost unearthly to those two unhappy souls in the room below.

Sturtevant's face twitched. His nerves were all wrong, and he was subject to small facial contortions.

The moon moved farther away from the tower, and, peeping over a gargoyle, shone still more directly into the room. On the wall opposite the window was a picture of the Dutch realistic school, a heavy hairless face, fat, with a look of vacuous excitement.

Condamine stared fixedly at it.

Suddenly the music stopped, and the man above shut the piano with a bang that jarred among the strings.

Condamine jumped up with a curse, looking as if he had been asleep. Then he yawned, and taking his cap and gown, without speaking left the room.

It was then upon nine o'clock, and he went to the Union and fought depression by firing off epigrams to a crowd of men in the smoking-room with the assured air of a man of vogue.
