"About twenty-three more minutes."

"Excellent!" said Dr. Yoritomo. "Would you be so good as to return at the end of that time?"

The therapist opened his mouth, closed it, then opened it again, and said: "Sure, Doc. I can get some other stuff done. I'll see you in twenty-three minutes. But don't let him out of there till I get back." He went out through the far door.

After the door closed, Dr. Yoritomo pulled up a chair and sat down. "There have been new developments," he said, "as you may have surmised."

The physical therapist, like many other of the personnel around the Institute, knew of Stanton's abilities, but he didn't know the purpose of the long series of operations that had made him what he was. Such persons knew about Stanton himself, but they knew nothing of any connection with the Nipe, although they might suspect. And all of them kept their knowledge and their suspicions to themselves.

"I guessed," Stanton said. "What is it, George?" He flexed his muscles under the caress of the hot, moist currents in the box.

He wondered why it was so important that the psychologist interrupt him while he was relaxing after strenuous exercise. Yoritomo looked excited in spite of his attempt to be calm. And yet Stanton knew that, whatever it was, it wasn't anything tremendously urgent or Dr. Yoritomo would be acting a great deal differently.

Yoritomo leaned forward in his chair, his thin lips in an excited smile, his black-irised eyes sparkling. "I had to come tell you. The sheer, utter beauty of it is too much to contain. Three times in a row was almost absolute, Bart. The probability that our hypotheses were correct was computed as straight nines to seven decimals. But now! The fourth time! Straight nines to twelve decimals!"

Stanton lifted an eyebrow. "Your Oriental calm is deserting you, George. I'm not reading you."

Yoritomo's smile became broader. "Ah! Sorry. I refer to the theory we have been discussing. About the peculiar mentality of our friend, the Nipe. You remember?"
