After that the silence had a more vital meaning. No pictures crowded his brain. He was simply keyed to a high point of expectancy, and therefore, when the door was opened silently, he sprang up as if in acknowledgment of an alarm and faced Barry. The latter closed the door behind him and glided after the big dog. He had almost crossed the big room when Byrne was able to speak.
"Mr. Barry!" he called.
The man hesitated.
"Mr. Barry," he repeated.
And Dan Barry turned. It was something like the act of the wolf the moment before; a swift movement—a flash of the eyes in something like defiance.
"Mr. Barry, are you leaving us?"
"I'm going outside."
"Are you coming back?"
"I dunno."
A great joy swelled in the throat of Doctor Byrne. He felt like shouting in triumph; yet he remembered once more how the girl had gone up the stairs, wearily, with fallen head. He decided that he would do what he could to keep the stranger with them, and though Randall Byrne lived to be a hundred he would never do a finer thing than what he attempted then. He stepped across the room and stood before Barry, blocking the way.
