Daneel interrupted smoothly. “There is interradio communication among these Solarian types. The robot you desire is being summoned. If it is slow in coming, it is part of the disturbance that has overtaken it as the result of what has occurred.”
Baley nodded. He might have guessed at interradio. In a world so thoroughly given over to robots some sort of intimate communication among them would be necessary if the system were not to break down. It explained how a dozen robots could follow when one robot had been summoned, but only when needed and not otherwise.
A robot entered. It limped, one leg dragging. Baley wondered why and then shrugged. Even among the primitive robots on Earth reactions to injury of the positronic paths were never obvious to the layman. A disrupted circuit might strike a leg’s functioning, as here, and the fact would be most significant to a roboticist and completely meaningless to anyone else.
Baley said cautiously, “Do you remember a colorless liquid on your master’s table, some of which you poured into a goblet for him?”
The robot said, “Yeth, mathter.” A defect in oral articulation, too!
Baley said, “What was the nature of the liquid?”
“It wath water, mathter.”
“Just water? Nothing else?”
“Jutht water, mathter.”
“Where did you get it?”
“From the rethervoir tap, mathter.”
“Had it been standing in the kitchen before you brought it in?”
“The mathter preferred it not too cold, mathter. It wath a thtanding order that it be poured an hour before mealth.”
How convenient, thought Baley, for anyone who knew that fact. He said, “Have one of the robots connect me with the doctor viewing your master as soon as he is available. And while that is being done, I want another one to explain how the reservoir tap works. I want to know about the water supply here.”
The doctor was available with little delay. He was the oldest Spacer Baley had ever seen, which meant, Baley thought, that he might be over three hundred years old. The veins stood out on his hands and his close-cropped hair was pure white. He had a habit of tapping his ridged front teeth with a fingernail, making a little clicking noise that Baley found annoying. His name was Altim Thool.
The doctor said, “Fortunately, he threw up a good deal of the dose. Still, he may not survive. It is a tragic event.” He sighed heavily.
“What was the poison, Doctor?” asked Baley.
“I’m afraid I don’t know.” (Click-click-click.)
Baley said, “What? Then how are you treating him?”
“Direct stimulation of the neuromuscular system to prevent paralysis, but except for that I am letting nature take its course.” His face, with its faintly yellow skin, like well-worn leather of superior quality, wore a pleading expression. “We have very little experience with this sort of thing. I don’t recall another case in over two centuries of practice.”
Baley stared at the other with contempt. “You know there are such things as poisons, don’t you?”
“Oh yes.” (Click-click.) “Common knowledge.”
“You have book-film references where you can gain some knowledge.”
“It would take days. There are numerous mineral poisons. We make use of insecticides in our society, and it is not impossible to obtain bacterial toxins. Even with descriptions in the films it would take a long time to gather the equipment and develop the techniques to test for them.”
“If no one on Solaria knows,” said Baley grimly, “I’d suggest you get in touch with one of the other worlds and find out. Meanwhile, you had better test the reservoir tap in Gruer’s mansion for poison. Get there in person, if you have to, and do it.”
Baley was prodding a venerable Spacer roughly, ordering him about like a robot and was quite unconscious of the incongruity of it. Nor did the Spacer make any protest.
Dr. Thool said doubtfully, “How could the reservoir tap be poisoned? I’m sure it couldn’t be.”
“Probably not,” agreed Baley, “but test it anyway to make sure.” The reservoir tap was a dim possibility indeed. The robot’s explanation had shown it to be a typical piece of Solarian self-care. Water might enter it from whatever source and be tailored to suit. Microorganisms were removed and non-living organic matter eliminated. The proper amount of aeration was introduced, as were various ions in just those trace amounts best suited to the body’s needs. It was very unlikely that any poison could survive one or another of the control devices.
Still, if the safety of the reservoir were directly established, then the time element would be clear. There would be the matter of the hour before the meal, when the pitcher of water (exposed to air, thought Baley sourly) was allowed to warm slowly, thanks to Gruer’s idiosyncrasy.
But Dr. Thool, frowning, was saying, “But how would I test the reservoir tap?”
“Jehoshaphat! Take an animal with you. Inject some of the water you take out of the tap into its veins, or have it drink some. Use your head, man. And do the same for what’s left in the pitcher, and if that’s poisoned, as it must be, run some of the tests the reference films describe. Find some simple ones. Do something.”
“Wait, wait. What pitcher?”
“The pitcher in which the water was standing. The pitcher from which the robot poured the poisoned drink.”
“Well, dear me–I presume it has been cleaned up. The household retinue would surely not leave it standing about.”
Baley groaned. Of course not. It was impossible to retain evidence with eager robots forever destroying it in the name of household duty. He should have ordered it preserved, but of course, this society was not his own and he never reacted properly to it.
Jehoshaphat!
Word eventually came through that the Gruer estate was clear; no sign of any unauthorized human present anywhere.
Daneel said, “That rather intensifies the puzzle, Partner Elijah, since it seems to leave no one in the role of poisoner.”
Baley, absorbed in thought, scarcely heard. He said, “What?.. Not at all. Not at all. It clarifies the matter.” He did not explain, knowing quite well that Daneel would be incapable of understanding or believing what Baley was certain was the truth.
Nor did Daneel ask for an explanation. Such an invasion of a human’s thoughts would have been most unrobotic.
Baley prowled back and forth restlessly, dreading the approach of the sleep period, when his fears of the open would rise and his longing for Earth increase. He felt an almost feverish desire to keep things happening.
He said to Daneel, “I might as well see Mrs. Delmarre again. Have the robot make contact.”
They walked to the viewing room and Baley watched a robot work with deft metal fingers. He watched through a haze of obscuring thought that vanished in startled astonishment when a table, elaborately spread for dinner, suddenly filled half the room.
Gladia’s voice said, “Hello.” A moment later she stepped into view and sat down. “Don’t look surprised, Elijah. It’s just dinnertime. And I’m very carefully dressed. See?”
She was. The dominant color of her dress was a light blue and it shimmered down the length of her limbs to wrists and ankles. A yellow ruff clung about her neck and shoulders, a little lighter than her hair, which was now held in disciplined waves.
Baley said, “I did not mean to interrupt your meal.”
“I haven’t begun yet. Why don’t you join me?”
He eyed her suspiciously. “Join you?”
She laughed. “You Earthmen are so funny. I don’t mean join me in personal presence. How could you do that? I mean, go to your own dining room and then you and the other one can dine with me.”
“But if I leave–”
“Your viewing technician can maintain contact.”
Daneel nodded gravely at that, and with some uncertainty Baley turned and walked toward the door. Gladia, together with her table, its setting, and its ornaments moved with him.
Gladia smiled en
couragingly. “See? Your viewing technician is keeping us in contact.”
Baley and Daneel traveled up a moving ramp that Baley did not recall having traversed before. Apparently there were numerous possible routes between any two rooms in this impossible mansion and he knew only few of them. Daneel, of course, knew them all.
And, moving through walls, sometimes a bit below floor level, sometimes a bit above, there was always Gladia and her dinner table.
Baley stopped and muttered, “This takes getting used to.”
Gladia said at once, “Does it make you dizzy?”
“A little.”
“Then I tell you what. Why don’t you have your technicians freeze me right here. Then when you’re in your dining room and all set, he can join us up.”
Daneel said, “I will order that done, Partner Elijah.”
Their own dinner table was set when they arrived, the plates steaming with a dark brown soup in which diced meat was bobbing, and in the center a large roast fowl was ready for the carving. Daneel spoke briefly to the serving robot and, with smooth efficiency, the two places that had been set were drawn to the same end of the table.
As though that were a signal, the opposite wall seemed to move outward, the table seemed to lengthen and Gladia was seated at the opposite end. Room joined to room and table to table so neatly that but for the varying pattern in wall and floor covering and the differing designs in tableware it would have been easy to believe they were all dining together in actual fact.
“There,” said Gladia with satisfaction. “Isn’t this comfortable?”
“Quite,” said Baley. He tasted his soup gingerly, found it delicious, and helped himself more generously. “YOU know about Agent Gruer?”
Trouble shadowed her face at once and she put her spoon down. “Isn’t it terrible? Poor Hannis.”
“You use his first name. Do you know him?”
“I know almost all the important people on Solaria. Most Solarians do know one another. Naturally.”
Naturally, indeed, thought Baley. How many of them were there, after all?
Baley said, “Then perhaps you know Dr. Altim Thool. He’s taking care of Gruer.”
Gladia laughed gently. Her serving robot sliced meat for her and added small, browned potatoes and slivers of carrots. “Of course I know him. He treated me.”
“Treated you when?”
“Right after the–the trouble. About my husband, I mean.”
Baley said in astonishment, “Is he the only doctor on the planet?”
“Oh no.” For a moment her lips moved as though she were counting to herself. “There are at least ten. And there’s one youngster I know of who’s studying medicine. But Dr. Thool is one of the best. He has the most experience. Poor Dr. Thool.”
“Why poor?”
“Well, you know what I mean. It’s such a nasty job, being a doctor. Sometimes you just have to see people when you’re a doctor and even touch them. But Dr. Thool seems so resigned to it and he’ll always do some seeing when he feels he must. He’s always treated me since I was a child and was always so friendly and kind and I honestly feel I almost wouldn’t mind if he did have to see me. For instance, he saw me this last time.”
“After your husband’s death, you mean?”
“Yes. You can imagine how he felt when he saw my husband’s dead body and me lying there.”
“I was told he viewed the body,” said Baley.
“The body, yes. But after he made sure I was alive and in no real danger, he ordered the robots to put a pillow under my head and give me an injection of something or other, and then get out. He came over by jet. Really! By jet. It took less than half an hour and he took care of me and made sure all was well. I was so woozy when I came to that I was sure I was only viewing him, you know, and it wasn’t till he touched me that I knew we were seeing, and I screamed. Poor Dr. Thool. He was awfully embarrassed, but I knew he meant well.”
Baley nodded. “I suppose there’s not much use for doctors on Solaria?”
“I should hope not.”
“I know there are no germ diseases to speak of. What about metabolic disorders? Atherosclerosis? Diabetes? Things like that?”
“It happens and it’s pretty awful when it does. Doctors can make life more livable for such people in a physical way, but that’s the least of it.”
“Oh?”
“Of course. It means the gene analysis was imperfect. You don’t suppose we allow defects like diabetes to develop on purpose. Anyone who develops such things has to undergo very detailed reanalysis. The mate assignment has to be retracted, which is terribly embarrassing for the mate. And it means no–no”–her voice sank to a whisper–” children.”
Baley said in a normal voice, “No children?”
Gladia flushed. “It’s a terrible thing to say. Such a word! Ch-children!”
“It comes easy after a while,” said Baley dryly.
“Yes, but if I get into the habit, I’ll say it in front of another Solarian someday and I’ll just sink into the ground.... Anyway, if the two of them have had children (see, I’ve said it again) already, the children have to be found and examined–that was one of Rikaine’s jobs, by the way–and well, it’s just a mess.”
So much for Thool, thought Baley. The doctor’s incompetence was a natural consequence of the society, and held nothing sinister. Nothing necessarily sinister. Cross him off, he thought, but lightly.
He watched Gladia as she ate. She was neat and precisely delicate in her movements and her appetite seemed normal. (His own fowl was delightful. In one respect, anyway–food–he could easily be spoiled by these Outer Worlds.)
He said, “What is your opinion of the poisoning, Gladia?”
She looked up. “I’m trying not to think of it. There are so many horrors lately. Maybe it wasn’t poisoning.”
“It was.”
“But there wasn’t anyone around?”
“How do you know?”
“There couldn’t have been. He has no wife, these days, since he’s all through with his quota of ch–you know what. So there was no one to put the poison in anything, so how could he be poisoned?”
“But he was poisoned. That’s a fact and must be accepted.”
Her eyes clouded over. “Do you suppose,” she said, “he did it himself?”
“I doubt it. Why should he? And so publicly?”
“Then it couldn’t be done, Elijah. It just couldn’t.”
Baley said, “On the contrary, Gladia. It could be done very easily. And I’m sure I know exactly how.”
8: A Spacer Is Defied
GLADIA SEEMED TO be holding her breath for a moment. It came out through puckered lips in what was almost a whistle. She said, “I’m sure I don’t see how. Do you know who did it?”
Baley nodded. “The same one who killed your husband.”
“Are you sure?”
“Aren’t you? Your husband’s murder was the first in the history of Solaria. A month later there is another murder. Could that be a coincidence? Two separate murderers striking within a month of each other on a crime-free world? Consider, too, that the second victim was investigating the first crime and therefore represented a violent danger to the original murderer.”
“Well!” Gladia applied herself to her dessert and said between mouthfuls, “If you put it that way, I’m innocent.”
“How so, Gladia?”
“Why, Elijah. I’ve never been near the Gruer estate, never in my whole life. So I certainly couldn’t have poisoned Agent Gruer. And if I haven’t–why, neither did I kill my husband.”
Then, as Baley maintained a stern silence, her spirit seemed to fade and the corners of her small mouth drooped. “Don’t you think so, Elijah?”
“I can’t be sure,” said Baley. “I’ve told you I know the method used to poison Gruer. It’s an ingenious one and anyone on Solaria could have used it, whether they were on the Gruer estate or not; whether they were ever on the Gruer estate or not
.”
Gladia clenched her hands into fists. “Are you saying I did it?”
“I’m not saying that.”
“You’re implying it.” Her lips were thin with fury and her high cheekbones were splotchy. “Is that all your interest in viewing me? To ask me sly questions? To trap me?”
“Now wait–”
“You seemed so sympathetic. So understanding. You–you Earthman!”
Her contralto had become a tortured rasp with the last word.
Daneel’s perfect face leaned toward Gladia and he said, “If you will pardon me, Mrs. Delmarre, you are holding a knife rather tightly and may cut yourself. Please be careful.”
Gladia stared wildly at the short, blunt, and undoubtedly quite harmless knife she held in her hand. With a spasmodic movement she raised it high.
Baley said, “You couldn’t reach me, Gladia.”
She gasped. “Who’d want to reach you? Ugh!” She shuddered in exaggerated disgust and called out, “Break contact at once!”
The last must have been to a robot out of the line of sight, and Gladia and her end of the room were gone and the original wall sprang back.
Daneel said, “Am I correct in believing you now consider this woman guilty?”
“No,” said Baley flatly. “Whoever did this needed a great deal more of certain characteristics than this poor girl has.”
“She has a temper.”
“What of that? Most people do. Remember, too, that she has been under a considerable strain for a considerable time. If I had been under a similar strain and someone had turned on me as she imagined I had turned on her, I might have done a great deal more than wave a foolish little knife.”
Daneel said, “I have not been able to deduce the technique of poisoning at a distance, as you say you have.”
Baley found it pleasant to be able to say, “I know you haven’t. You lack the capacity to decipher this particular puzzle.”
He said it with finality and Daneel accepted the statement as calmly and as gravely as ever.
Baley said, “I have two jobs for you, Daneel.”
“And what are they, Partner Elijah?”
