"What do you mean?"
"Not so skeered-like. He was out here when you went to the Cabin for them plans——"
"Out here?" said Peter in amazement.
Andy nodded. "He seemed more natural-like,—asked what the countersign was and said mebbe we'd all be goin' back to the mills after a night or so."
"Oh, did he? That's good. You're pretty tired of this night work?"
"Not so long as it pays good. But what did he mean by changin' the guards?"
"He didn't say anything to me about it," said Peter, concealing his surprise.
"Oh, didn't he? Well, he took Andy off the privet hedge and sent him down to the clump of pines near the road."
"I see," said Peter. "Why?"
"You've got me, Mister. If there's trouble to-night, there ain't no one at the back of the house at all. We're one man short."
