"Gentlemen, before we go any further, I must conduct one final experiment in order to justify Operation Mapcase. I will not explain it just yet." He looked at Lenny Poe, a small, dark-haired man with a largish nose. "Mr. Poe, can you contact your brother at this moment?" Lenny Poe was a man who was not overawed by anyone, and had no inclination to be formal, not even toward the President. "Yeah, sure," he said matter-of-factly. [Illustration] The President glanced at his watch. "It is now five minutes of ten. That makes it five minutes of six in the evening in Moscow. Is your brother free to move around? That is, can he go to a certain place in the city?" Lenny closed his eyes for a moment, then opened them. "Rafe says he can go any place that the average citizen would be allowed to go." "Excellent," said the President. He gave Lenny an address--an intersection of two streets not far from Red Square. "Can he get there within fifteen minutes?" "Make it twenty," said Lenny. "Very well. Twenty minutes. When he gets there, I'll ask you to relay further instructions." Lenny Poe closed his eyes, folded his arms, and relaxed in his chair. The other three men waited silently. Nineteen minutes later, Lenny opened his eyes and said: "O.K. He's there. Now what?" "There is a lamppost on that corner, I believe," said the President. "Can your brother see it?" Lenny closed his eyes again. "Sure. There's a guy leaning against it." The President's eyes brightened. "Describe him!" Lenny, eyes still closed, said: "Five feet ten, heavy set, gray hair, dark-rimmed glasses, brown suit, flashy necktie. By the cut of his clothes, I'd say he was either British or American, probably American. Fifty-five or fifty-six years old." It was obvious to the Secretary of Defense and to Colonel Spaulding that the President was suppressing some inward excitement. "Very good, Mr. Poe!" he said. "Now, you will find a box of colored pencils and a sketch pad in that desk over there. Can you draw me a fairly accurate sketch of that man?" "Yeah, sure." Lenny opened his eyes, moved over to the desk, took out the pencils and sketch pad, and went to work. He had to close his eyes occasionally, but his work was incredibly rapid and, at the same time, almost photographically accurate. As the picture took form, the President's inward excitement increased perceptibly. When it was finally finished, Lenny handed the sketch to the President without a word. The President took it eagerly and his face broke out in his famous grin. "Excellent! Perfect!" He looked at Lenny. "Your brother hasn't attracted the man's attention in any way, has he?" "Nope," said Lenny. "Fine. The experiment is over. Relay my thanks to your brother. He can go ahead with whatever he was doing now." "I don't quite understand," said the Secretary of State.
