In the corridor outside, two white-clad interns stopped at the door of Ollie's room and listened. They could not properly have been described as man and woman, but at any rate one was male and the other female. If you didn't look at them too closely, they seemed to be human, which, of course, was what they wanted you to think. "Just as I said," observed Zolto. "They intend to operate. And their attention has already been drawn to the nut." "We can stop them by violence, if necessary. But I abhor violence." "I know, dear," Zolto said thoughtfully. "What has happened is clear enough. He kept sending all that food through, and our people analyzed it and discovered what it was. They must have been surprised to discover no message from us, but after a while they arrived at the conclusion that we needed some of our own food and they sent it to us. It's a good thing that they didn't send more of it at one time." "The poor man must be in agony as it is." "Never mind the poor man. Think of our own situation." "But don't you see, Zolto? His digestive juices can't dissolve such unfamiliar chemical constituents, and his stomach must be greatly irritated." She broke off for a moment as the nurse came past them, giving them only a casual glance. The X-ray specialist followed shortly, his face reflecting the bewilderment he felt as a result of studying the plate he was holding. "That leaves only Dr. Manson with him," said Zolto. "Pojim, I have a plan. Do you have any of those pandigestive tablets with you?" "I always carry them. I never know when in this world I'll run into something my stomach can't handle." "Fine." Zolto stepped back from the doorway, cleared his throat, and began to yell, "Calling Dr. Manson! Dr. Manson, report to surgery!" "You've been seeing too many of their movies," said Pojim. But Zolto's trick worked. They heard Dr. Manson mutter, "Damn!" and saw him rush into the corridor. He passed them without even noticing that they were there. "We have him to ourselves," said Zolto. "Quick, the tablets." They stepped into the room, where Zolto passed a small inhalator back and forth under Ollie's nose. Ollie jerked away from it, and his eyes opened. "Take this," said Pojim, with a persuasive smile. "It will ease your pain." And she put two tablets into Ollie's surprised mouth. Automatically, Ollie swallowed and the tablets sped down to meet the collection in his stomach. Pojim gave him another smile, and then she and Zolto were out of the room. To Ollie, things seemed to be happening in more and more bewildering fashion. No sooner had these strange doctors left than Dr. Manson came rushing back, cursing, in a way that would have shocked Hippocrates, the unknown idiot who had summoned him to surgery. Then the nurse came in, with a paper. Ollie gathered that he was being asked to sign something. He shook his head vigorously. "Not me. I don't sign _nothin'_, sister."
