"Look here, Yeasky," he said, as the man wheeled in nervous haste, "who was that chap you spoke to at that motor car?"

Yeasky hesitated a moment and then looked the officer full in the eyes.

"I do not know," he said; "I thought it was Commander Harris. I was going to ask him about those coils which have not come yet. When I found I mistook, I was ashamed."

Armitage returned the electrician's gaze for a second. He was at a loss. There was a slight resemblance between Harris and the Prince, to be sure. Then, suddenly, as he recalled the incident at the Grand Central Station and his fears of the previous evening, a wave of anger swept over him and he thrust his face belligerently toward the workman, the muscles of his right shoulder calling nervously for action.

"Yeasky," he said, "you are lying. Who do you think you are up against,—a child?" He shook his finger in the man's face. "Now quick; tell me what business you had with that man." Yeasky drew himself up with an air of offended dignity not altogether compatible with his putative station in life. Armitage noticed it and pressed on.

"Do you hear?" he said in a low tense voice. He was already past saving; he had never been a diplomat. "Hurry up, speak, or I 'll knock your Polack head off."

Before the man could reply, Thornton, who had hurried up, interposed.

"What's the matter, Jack? Did this gentleman have the misfortune to demand all of the sidewalk?"

Armitage replied over his shoulder.

"You go along, Joe, and leave this to me. I saw this man trying to talk to that Russian Prince—and he's employed on confidential work in the shops."
