"But the important thing here," Dr. O'Connor said, "is the timing. You see, Charlie was incapable of continued concentration. He could not keep his mind focused on another mind for very long, before he hopped to still another. The actual amount of time concentrated on any given mind at any single given period varied from a minimum of one point three seconds to a maximum of two point six. The timing samples, when plotted graphically over a period of several months, formed a skewed bell curve with a mode at two point oh seconds."
"Ah," Malone said, wondering if a skewed ball curve was the same thing as a belled skew curve, and if not, why not?
"It was, in fact," Dr. O'Connor continued relentlessly, "a sudden variation in those timings which convinced us that there was another telepath somewhere in the vicinity. We were conducting a second set of reading experiments, in precisely the same manner as the first set, and, for the first part of the experiment, our figures were substantially the same. But—" He stopped.
"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, "the other two geniuses both 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."
"Hmm," Malone said, feeling that he ought to be saying something.
