"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.

"I felt it necessary to make one final experiment of my own devising," the President said. "I wanted Raphael Poe to go to a particular place at a particular time, with no advance warning, to transmit a picture of something he had never seen before. I arranged this test myself, and I am positive that there could be no trickery."

"Never seen before?" the Secretary repeated bewilderedly. He gestured at the sketch. "Why, that's obviously Bill Donovan, of the Moscow delegation. Poe could have seen a photograph of him somewhere before."

"Even so," the President pointed out, "there would be no way of knowing that he would be at that spot. But that's beside the point. Look at that necktie!"

"I had noticed it," the Defense Secretary admitted.
