"Naturally. Your drinks weren't drugged."
"Drugged?" shrieked Miss Dupont. "You doped him?"
"That's rather obvious, isn't it?"
"But—what for?" Dr. Kalmar stammered.
"Same reason I slipped you a mickey not long after you got here. We can't take any chances that he'll ship back to Earth. You see?"
"I don't," raged Miss Dupont. "I think it's a cheap, dirty, foul trick and it won't work, either. You can't keep him drugged."
"I don't like you talking to Dr. Lowell like that," said Dr. Kalmar indignantly.
"You should be the last one to object," Mrs. Kalmar pointed out. "He said he drugged you, too."
"I know," Dr. Kalmar said blankly. "I don't understand—"
"You will," promised Dr. Lowell. "Just come along and don't interfere. Better give him the order; it'll keep things straighter."
