He held out his hand. The robot approached and delivered a dozen of them. Baley put the original arrow, the one that had hit the tree, carefully at his feet, and looked the others over one by one. He handed them back and lifted the original arrow again.
He said, "Why did you give this particular arrow to the boy?"
"No reason, master. He had asked for an arrow some time earlier and this was the one my hand touched first. He looked about for a target, then noticed you and asked who the strange human was. I explained - "
"I know what you explained. This arrow you handed him is the only one with gray vanes at the rear. The others have black vanes."
The robot simply stared.
Baley said, "Did you guide the youngster here?"
"We walked randomly, master."
The Earthman looked through the gap between two trees through which the arrow had hurled itself toward its mark. He said, "Would it happen, by any chance, that this youngster, Bik, was the best archer you have here?"
The robot bent his head. "He is the best, master."
Klorissa gaped. "How did you ever come to guess that?"
"It follows," said Baley dryly. "Now please observe this gray-vaned arrow and the others. The gray-vaned arrow is the only one that seems oily at the point. I'll risk melodrama, ma'am, by saying that your warning saved my life. This arrow that missed me is poisoned."
13. A ROBOTICIST IS CONFRONTED
Klorissa said, "Impossible! Skies above, absolutely impossible!"
"Above or below or any way you wish it. Is there an animal on the farm that's expendable? Get it and scratch it with the arrow and see what happens."
"But why should anyone want to - "
Baley said harshly, "I know why. The question is, who?"
"No one."
Baley felt the dizziness returning and he grew savage. He threw the arrow at her and she eyed the spot where it fell.
"Pick it up," Baley cried, "and if you don't want to test it, destroy it. Leave it there and you'll have an accident if the children get at it."
She picked it up hurriedly, holding it between forefinger and thumb.
Baley ran for the nearest entrance to the building and Klorissa was still holding the arrow, gingerly, when she followed him back indoors.
Baley felt a certain measure of equanimity return with the comfort of enclosure. He said, "Who poisoned the arrow?"
"I can't imagine."
"I suppose it isn't likely the boy did it himself. Would you have any way of telling who his parents were?"
"We could check the records," said Klorissa gloomily.
"Then you do keep records of relationships?"
"We have to for gene analysis."
"Would the youngster know who his parents were?"
"Never," said Klorissa energetically.
"Would he have any way of finding out?"
"He would have to break into the records room. Impossible."
"Suppose an adult visited the estate and wanted to know who his child was - "
Klorissa flushed. "Very unlikely."
"But suppose. Wou]d he be told if he were to ask?"
"I don't know. It isn't exactly illegal for him to know. It certainly isn't customary."
"Would you tell him?"
"I'd try not to. I know Dr. Delmarre wouldn't have. He believed knowledge of relationship was for gene analysis only. Before him things may have been looser... . Why do you ask all this, anyway?"
"I don't see how the youngster could have a motive on his own account. I thought that through his parents he might have."
"This is all horrible." In her disturbed state of mind Klorissa approached more closely than at any previous time. She even stretched out an arm in his direction. "How can it all be happening? The boss killed; you nearly killed. We have no motives for violence on Solaria. We all have all we can want, so there is no personal ambition. We have no knowledge of relationship, so there is no family ambition. We are all in good genic health."
Her face cleared all at once. "Wait. This arrow can't be poisoned. I shouldn't let you convince me it is."
"Why have you suddenly decided that?"
"The robot with Bik. He would never have allowed poison. It's inconceivable that he could have done anything that might bring harm to a human being. The First Law of Robotics makes sure of that."
Baley said, "Does it? What is the First Law, I wonder?"
Klorissa stared blankly. "What do you mean?"
"Nothing. You have the arrow tested and you will find it poisoned." Baley himself was scarcely interested in the matter. He knew it for poison beyond any internal questionings. He said, "Do you still believe Mrs. Delmarre to have been guilty of her husband's death?"
"She was the only one present."
"I see. And you are the only other human adult present on this estate at a time when I have just been shot at with a poisoned arrow."
She cried energetically, "I had nothing to do with it."
"Perhaps not. And perhaps Mrs. Delmarre is innocent as well. May I use your viewing apparatus?"
"Yes, of course."
Baley knew exactly whom he intended to view and it was not Gladia. It came as a surprise to himself then to hear his voice say, "Get Gladia Delmarre."
The robot obeyed without comment, and Baley watched the manipulations with astonishment, wondering why he had given the order.
Was it that the girl had just been the subject of discussion, or was it that he had been a little disturbed over the manner of the end of their last viewing, or was it simply the sight of the husky, almost overpoweringly practical figure of Klorissa that finally enforced the necessity of a glimpse of Gladia as a kind of counterirritant?
