It is difficult to transmit information these days. It is actually easier for the espioneur to transmit it than to get it, generally speaking, but it is difficult for him to do both jobs at once, so the spy ring's two major parts consist of the ones who get the information from the enemy and the ones who transmit it back to their employers. Without magic, it is difficult for a single spy to be of any benefit. And "magic," in this case, can be defined as some method by which information can be either obtained or transmitted without fear of discovery by the enemy. During World War I, a competent spy equipped with a compact transistorized short-wave communications system could have had himself a ball. If the system had included a miniature full-color television camera, he could have gone hog wild. In those days, such equipment would have been magic. All this is not _à propos_ of nothing. Mr. Raphael Poe was, in his own way, a magician. It is not to be supposed that the United States of America had no spy rings in the Union of Soviet Socialist Republics at that time. There were plenty of them. Raphael Poe could have, if it were so ordained, availed himself of the services of any one or all of them. He did not do so for two reasons. In the first place, the more people who are in on a secret, the more who can give it away. In other words, a ring, like a chain, is only as strong as its weakest section. In the second place, Raphael Poe didn't need any assistance in the first place. That is, he needed no more assistance that most magicians do--a shill in the audience. In this particular case, the shill was his brother, Leonard Poe. * * * * * Operation Mapcase was as ultra-secret as it could possibly be. Although there were perhaps two dozen men who knew of the existence of the operation by its code name, such as the Naval officers who had helped get Raphael Poe to his destination, there were only five men who really knew what Operation Mapcase was all about. Two of these were, of course, Raphael and Leonard Poe. Two others were the President of the United States and the Secretary of Defense. The fifth was Colonel Julius T. Spaulding, of United States Army Intelligence. On the seventh day after Raphael Poe's arrival in Moscow, the other four men met in Blair House, across the street from the White House, in a room especially prepared for the purpose. No one but the President knew the exact purpose of the meeting, although they had an idea that he wanted more information of some kind. The President himself was the last to arrive. Leaving two Secret Service men standing outside the room, he carefully closed the door and turned to face the Secretary of Defense, Colonel Spaulding, and Leonard Poe. "Sit down, gentlemen," he said, seating himself as he spoke.
