“Thank you,” muttered Enderby. His voice gained strength and confidence. “I don’t know what your motives are, Baley, or why you should try to ruin me this way, but I’ll get to the bottom—”
“Wait,” said Baley. “I’m not through. I’ve got this.”
He slammed the aluminum cube on Enderby’s desk, and tried to feel the confidence he hoped he was radiating. For half an hour now, he had been hiding from himself one little fact: that he did not know what the picture showed. He was gambling, but it was all that was left to do.
Enderby shrank away from the small object. “What is it?”
“It isn’t a bomb,” said Baley, sardonically. “Just an ordinary microprojector.”
“Well? What will that prove?”
“Suppose we see.” His fingernail probed at one of the slits in the cube, and a corner of the Commissioner’s office blanked out, then lit up in an alien scene in three dimensions.
It reached from floor to ceiling and extended out past the walls of the room. It was awash with a gray light of a sort the City’s utilities never provided.
Baley thought, with a pang of mingled distaste and perverse attraction: It must be the dawn they talk about.
The pictured scene was of Dr. Sarton’s dome. Dr. Sarton’s dead body, a horrible, broken remnant, filled its center.
Enderby’s eyes bulged as he stared.
Baley said, “I know the Commissioner isn’t a killer. I don’t need you to tell me that, Daneel. If I could have gotten around that one fact earlier, I would have had the solution earlier. Actually, I didn’t see a way out of it until an hour ago when I carelessly said to you that you had once been curious about Bentley’s contact lenses.—That was it, Commissioner. It occurred to me then that your nearsightedness and your glasses were the key. They don’t have nearsightedness on the Outer Worlds, I suppose, or they might have reached the true solution of the murder almost at once. Commissioner, when did you break your glasses?”
The Commissioner said, “What do you mean?”
Baley said, “When I first saw you about this case, you told me you had broken your glasses in Spacetown. I assumed that you broke them in your agitation on hearing the news of the murder, but you never said so, and I had no reason for making that assumption. Actually, if you were entering Spacetown with crime on your mind, you were already sufficiently agitated to drop and break your glasses before the murder. Isn’t that so, and didn’t that, in fact, happen?”
R. Daneel said, “I do not see the point, partner Elijah.”
Baley thought: I’m partner Elijah for ten minutes more. Fast! Talk fast! And think fast!
He was manipulating Sarton’s dome image as he spoke. Clumsily, he expanded it, his fingernails unsure in the tension that was overwhelming him. Slowly, in jerks, the corpse widened, broadened, heightened, came closer. Baley could almost smell the stench of its scorched flesh. Its head, shoulders, and one upper arm lolled crazily, connected to hips and legs by a blackened remnant of spine from which charred rib stumps jutted.
Baley cast a side glance at the Commissioner. Enderby had closed his eyes. He looked sick. Baley felt sick, too, but he had to look. Slowly he circled the trimensional image by means of the transmitter controls, rotating it, bringing the ground about the corpse to view in successive quadrants. His fingernail slipped and the imaged floor tilted suddenly and expanded till floor and corpse alike were a hazy mass, beyond the resolving power of the transmitter. He brought the expansion down, let the corpse slide away.
He was still talking. He had to. He couldn’t stop till he found what he was looking for. And if he didn’t, all his talk might be useless. Worse than useless. His heart was throbbing, and so was his head.
He said, “The Commissioner can’t commit deliberate murder. True! Deliberate. But any man can kill by accident. The Commissioner didn’t enter Spacetown to kill Dr. Sarton. He came in to kill you, Daneel, you! Is there anything in his cerebroanalysis that says he is incapable of wrecking a machine? That’s not murder, merely sabotage.
“He is a Medievalist, an earnest one. He worked with Dr. Sarton and knew the purpose for which you were designed, Daneel. He feared that purpose might be achieved, that Earthmen would eventually be weaned away from Earth. So he decided to destroy you, Daneel. You were the only one of your type manufactured as yet and he had good reason to think that by demonstrating the extent and determination of Medievalism on Earth, he would discourage the Spacers. He knew how strong popular opinion was on the Outer Worlds to end the Spacetown project altogether. Dr. Sarton must have discussed that with him. This, he thought, would be the last nudge in the proper direction.
“I don’t say even the thought of killing you, Daneel, was a pleasant one. He would have had R. Sammy do it, I imagine, if you didn’t look so human that a primitive robot such as Sammy could not have told the difference, or understood it. First Law would stop him. Or the Commissioner would have had another human do it if he, himself, were not the only one who had ready access to Spacetown at all times.
“Let me reconstruct what the Commissioner’s plan might have been. I’m guessing, I admit, but I think I’m close. He made the appointment with Dr. Sarton, but deliberately came early, at dawn, in fact. Dr. Sarton would be sleeping, I imagine, but you, Daneel, would be awake. I assume, by the way, you were living with Dr. Sarton, Daneel.”
The robot nodded. “You are quite right, partner Elijah.”
Baley said, “Then let me go on. You would come to the dome door, Daneel, receive a blaster charge in the chest or head, and be done with. The Commissioner would leave quickly, through the deserted streets of Spacetown’s dawn, and back to where R. Sammy waited. He would give him back the blaster, then slowly walk again to Dr. Sarton’s dome. If necessary, he would ‘discover’ the body himself, though he would prefer to have someone else do that. If questioned concerning his early arrival, he could say, I suppose, that he had come to tell Dr. Sarton of rumors of a Medievalist attack on Spacetown, urge him to take secret precautions to avoid open trouble between Spacers and Earthmen. The dead robot would lend point to his words.
“If they asked about the long interval between your entering Spacetown, Commissioner, and your arrival at Dr. Sarton’s dome, you could say—let’s see—that you saw someone lurking through the streets and heading for open country. You pursued for a while. That would also encourage them along a false path. As for R. Sammy, no one would notice him. A robot among the truck farms outside the City is just another robot.
“How close am I, Commissioner?”
Enderby writhed, “I didn’t—”
“No,” said Baley, “you didn’t kill Daneel. He’s here, and in all the time he’s been in the City, you haven’t been able to look him in the face or address him by name. Look at him now, Commissioner.”
Enderby couldn’t. He covered his face with shaking hands.
Baley’s shaking hands almost dropped his transmitter. He had found it.
The image was now centered upon the main door to Dr. Sarton’s dome. The door was open; it had been slid into its wall receptacle along its shining metal runner grooves. Down within them. There! There!
The sparkle was unmistakable.
“I’ll tell you what happened,” said Baley. “You were at the dome when you dropped your glasses. You must have been nervous and I’ve seen you when you’re nervous. You take them off; you wipe them. You did that then. But your hands were shaking and you dropped them; maybe you stepped on them. Anyway, they were broken, and just then, the door opened and a figure that looked like Daneel faced you.
