He became aware of that and put down his fork with a muffled, "Jehoshaphat!"
He said, "Daneel!"
R. Daneel had been sitting at another table, as though he wished to leave the obviously preoccupied Baley in peace, or as though he required privacy himself. Baley was past caring which.
Daneel stood up, moved to Baley's table, and sat down again. "Yes, partner Elijah?"
Baley did not look at him. "Daneel, I'll need your co-operation."
"In what way?"
"They will question Jessie and myself. That is certain. Let me answer the questions in my own way. Do you understand?"
"I understand what you say, of course. Nevertheless, if I am asked a direct question, how is it possible for me to say anything but what is so?"
"If you are asked a direct question, that's another matter. I ask only that you don't volunteer information. You can do that, can't you?"
"I believe so, Elijah, provided it does not appear that I am hurting a human being by remaining silent."
Baley said, grimly, "You will hurt me if you don't. I assure you of that."
"I do not quite understand your point of view, partner Elijah. Surely the matter of R. Sammy cannot concern you."
"No? It all centers about motive, doesn't it? You've questioned the motive. The Commissioner questioned it. I do, for that matter. Why should anyone want to kill R. Sammy? Mind you, it's not just a question of who would want to smash up robots in general. Any Earthman, practically, would want to do that. The question is, who would want to single out R. Sammy. Vincent Barrett might, but the Commissioner said he couldn't get hold of an alpha-sprayer, and he's right. We have to look somewhere else, and it so happens that one other person has a motive. It glares out. It yells. It stinks to top level."
"Who is the person, Elijah?"
And Baley said, softly, "I am, Daneel."
R. Daneel's expressionless face did not change under the impact of the statement. He merely shook his head.
Baley said, "You don't agree. My wife came to the office today. They know that already. The Commissioner is even curious. If I weren't a personal friend, he wouldn't have stopped his questioning so soon. Now they'll find out why. That's certain. She was part of a conspiracy; a foolish and harmless one, but a conspiracy just the same. And a policeman can't afford to have his wife mixed up with anything like that. It would be to my obvious interest to see that the matter was hushed up.
"Well, who knew about it? You and I, of course, and Jessie - and R. Sammy. He saw her in a state of panic. When he told her that we had left orders not to be disturbed, she must have lost control. You saw the way she was when she first came in."
R. Daneel said, "It is unlikely that she said anything incriminating to him."
"That may be so. But I'm reconstructing the case the way they will. They'll say she did. There's my motive. I killed him to keep him quiet."
"They will not think so."
"They will think so. The murder was arranged deliberately in order to throw suspicion on me. Why use an alpha-sprayer? It's a rather risky way. It's hard to get and it can be traced. I think that those were the very reasons it was used. The murderer even ordered R. Sammy to go into the photographic supply room and kill himself there. It seems obvious to me that the reason for that was to have the method of murder unmistakable. Even if everyone was so infantile as not to recognize the alpha-sprayer immediately, someone would be bound to notice fogged photographic film in fairly short order."
"How does that all relate to you, Elijah?"
Bailey grinned tightly, his long face completely devoid of humor. "Very neatly. The alpha-sprayer was taken from the Williamsburg power plant. You and I passed through the Williamsburg power plant yesterday. We were seen, and the fact will come out. That gives me opportunity to get the weapon as well as motive for the crime. And it may turn out that we were the last ones to see or hear R. Sammy alive, except for the real murderer, of course."
"I was with you in the power plant and I can testify that you did not have the opportunity to steal an alpha-sprayer."
"Thanks," said Baley sadly, "but you're a robot and your testimony will be invalid."
"The Commissioner is your friend. He will listen."
"The Commissioner has a job to keep, and he already is a bit uneasy about me. There's only one chance of saving myself from this very nasty situation."
"Yes?"
"I ask myself, why am I being framed? Obviously to get rid of me. But why? Again obviously, because I am dangerous to someone. I am doing my best to be dangerous to whoever killed Dr. Sarton in Spacetown. That might mean the Medievalists, of course, or at least, the inner group among them. It would be this inner group that would know I had passed through the power plant; at least one of them might have followed me along the strips that far, even though you thought we had lost them.
"So the chances are that if I find the murderer of Dr. Sarton, I find the man or men who are trying to get me out of the way. If I think it through, if I crack the case, if I can only crack it, I'll be safe. And Jessie. I couldn't stand to have her. - But I don't have much time." His fist clenched and unclenched spasmodically. "I don't have much time."
Baley looked at R. Daneel's chiseled face with a sudden burning hope. Whatever the creature was, he was strong and faithful, animated by no selfishness. What more could you ask of any friend? Baley needed a friend and he was in no mood to cavil at the fact that a gear replaced a blood vessel in this particular one.
But R. Daneel was shaking his head.
