"I've come for him!" As if in answer, the great, shaggy dog slipped through the entrance past his master and glided across the room.

As he passed, Kate held out a hand to him.

She called softly: "Bart!" but she was greeted with a silent baring of fangs; and she caught her hand back against her breast, with the tears springing in her eyes.

On the other side of the room the black dog paused and looked back to his master, while Byrne realised with a shudder that the door before which it stood was the door through which Buck Daniels had disappeared.

Straight to that door Barry stepped, and Byrne realised, with an eerie emotion, that the footfalls made no sound.
Before he reached the door, however, the girl started forward and sprang before him.
