"Yes?" Malone said, shifting his feet and trying to take some weight off his left foot by standing on his right leg. Then he stood on his left leg. It didn't seem to do any good. "I should explain," Dr. O'Connor said, "that we were conducting this series with a new set of test subjects: some of the scientists here at Yucca Flats. We wanted to see if the intelligence quotients of the subjects affected the time of contact which Charlie was able to maintain. Naturally, we picked the men here with the highest IQ's, the two men we have who are in the top echelon of the creative genius class." He cleared his throat. "I did not include myself, of course, since I wished to remain an impartial observer, as much as possible." "Of course," Malone said without surprise. "The other two geniuses," Dr. O'Connor said, "happen to be connected with the project known as Project Isle--an operation whose function I neither know, nor care to know, anything at all about." Malone nodded. Project Isle was the non-rocket spaceship. Classified. Top Secret. Ultra-Secret. And, he thought, just about anything else you could think of. "At first," Dr. O'Connor was saying, "our detector recorded the time periods of ... ah mental invasion as being the same as before. Then, one day, anomalies began to appear. The detector showed that the minds of our subjects were being held for as long as two or three minutes. But the phrases repeated by Charlie during these periods showed that his own contact time remained the same; that is, they fell within the same skewed bell curve as before, and the mode remained constant if nothing but the phrase length were recorded." "Hm-m-m," Malone said, feeling that he ought to be saying something. Dr. O'Connor didn't notice him. "At first we thought of errors in the detector machine," he went on. "That worried us not somewhat, since our understanding of the detector is definitely limited at this time. We do feel that it would be possible to replace some of the electronic components with appropriate symbolization like that already used in the purely psionic sections, but we have, as yet, been unable to determine exactly which electronic components must be replaced by what symbolic components." Malone nodded, silently this time. He had the sudden feeling that Dr. O'Connor's flow of words had broken itself up into a vast sea of alphabet soup, and that he, Malone, was occupied in drowning in it. "However," Dr. O'Connor said, breaking what was left of Malone's train of thought, "young Charlie died soon thereafter, and we decided to go on checking the machine. It was during this period that we found someone else reading the minds of our test subjects--sometimes for a few seconds, sometimes for several minutes." "Aha," Malone said. Things were beginning to make sense again. _Someone else._ That, of course, was the spy.
