"You see, Nichols," he went on as he set his empty glass down, "I know what I'm about. There is somebody trying to get at me. It's no dream—no hallucination. You know that too, now. I saw him—I would have shot him through the window—if it hadn't been for Peggy—and the others—but I—I didn't dare—for reasons. She mustn't know——" And then eagerly, "She doesn't suspect anything yet, does she, Nichols?"

Peter gestured over his shoulder in the direction of the sounds which still came from below.

"That's all right. To-morrow they'll be leaving for New York, I hope. And then we'll meet this issue squarely. You say the man has gone. Why do you think so?"

"Isn't it reasonable to think so? His visit was merely a reconnoissance. I think he had probably been lying out in the underbrush all day, getting the lay of the land, watching what we were doing—seeing where the men were placed.

From his failure to do so, there is one definite conclusion to draw—and that is that he wants to see you—to talk with you——"

McGuire fairly threw himself from his chair as he roared,

"I can't see him. I won't. I won't see anybody. I've got the law on my side. A man's house is his castle. A fellow prowls around here in the dark. He's been seen—if he's shot it's his own lookout. And he will be shot before he reaches me. You hear me? Your men must shoot—shoot to kill. If they fail I'll——"
