Of what did he think as he walked?
It carried Byrne automatically out into the darkest night, with a wind in his face, and the rhythm of a long striding horse carrying him on to a destination unknown.
Here he heard a soft scratching, repeated, at the door.

When it came again he rose and opened the door--at once the tall, shaggy dog slipped through the opening and glided past him.

It startled Byrne oddly to see the animal stealing away, as if Barry himself had been leaving.

He called to the beast, but he was met by a silent baring of white fangs that stopped him in his tracks.

The great dog was gone without a sound, and Byrne closed the door again without casting a look inside.
