"They didn't come there together."
"Oh, didn't they? Where was you?"
"I was hiding, and watching them."
"So you saw 'em all when they arrived there, did you?"
"Yes."
"Who got there first?"
"This man—Pat."
"Did the others appear to know him?"
"No; but they didn't appear to know each other, either."
"But if they were spies, and you afterward proved that they were, and if they got there, and found Pat already there, it would be natural that they should act as if they didn't know each other, wouldn't it, in order to deceive him?"
