"None," said Gruer sharply.
"And where is the robot, now?"
"Scrapped," said Gruer.
Baley raised his eyebrows. "This is a rather peculiar case. No motive, no means, no witnesses, no evidence. Where there was some evidence to begin with, it was destroyed. You have only one suspect and everyone seems convinced of her guilt; at least, everyone is certain no one else can be guilty.' That's your opinion, too, obviously. The question then is: Why was I sent for?"
Gruer frowned. "You seem upset, Mr. Baley." He turned abruptly to Daneel. "Mr. Olivaw."
"Yes, Agent Gruer."
"Won't you please go through the dwelling and make sure all windows are closed and blanked out? Plainclothesman Baley may be feeling the effects of open space."
The statement astonished Baley. It was his impulse to deny Gruer's assumption and order Daneel to keep his place when, on the brink, he caught something of panic in Gruer's voice, something of glittering appeal in his eyes.
He sat back and let Daneel leave the room.
It was as though a mask had dropped from Gruer's face, leaving it naked and afraid. Gruer said, "That was easier than I had thought. I'd planned so many ways of getting you alone. I never thought the Auroran would leave at a simple request, and yet I could think of nothing else to do."
Baley said, "Well, I'm alone now."
Gruer said, "I couldn't speak freely in his presence. He's an Auroran and he is here because he was forced on us as the price of having you." The Solarian leaned forward. "There's something more
to this than murder. I am not concerned only with the matter of who did it. There are parties on Solaria, secret organizations... ."
Baley stared. "Surely, I can't help you there."
"Of course you can. Now understand this: Dr. Delmarre was a Traditionalist. He believed in the old ways, the good ways. But there are new forces among us, forces for change, and Delmarre has been silenced."
"By Mrs. Delmarre?"
"Hers must have been the hand. That doesn't matter. There is an organization behind her and that is the important matter."
"Are you sure? Do you have evidence?"
"Vague evidence, only. I can't help that. Rikaine Delmarre was on the track of something. He assured me his evidence was good, and I believe him. I knew him well enough to know him as neither fool nor child. Unfortunately, he told me very little. Naturally, he wanted to complete his investigation before laying the matter completely open to the authorities. He must have gotten close to completion, too, or they wouldn't have dared the risk of having him openly slaughtered by violence. One thing Delmarre told me, though. The whole human race is in danger."
Baley felt himself shaken. For a moment it was as though he were listening to Minnim again, but on an even larger scale. Was everyone going to turn to him with cosmic dangers?
"Why do you think I can help?" he asked.
"Because you're an Earthman," said Gruer. "Do you understand? We on Solaria have no experience with these things. In a way, we don't understand people. There are too few of us here."
He looked uneasy. "I don't like to say this, Mr. Baley. My colleagues laugh at me and some grow angry, but it is a definite feeling I have. It seems to me that you Earthmen must understand people far better than we do, just by living among such crowds of them. And a detective more than anyone. Isn't that so?"
Baley half nodded and held his tongue.
Gruer said, "In a way, this murder was fortunate. I have not dared speak to the others about Delmarre's investigation, since I wasn't sure who might be involved in the conspiracy, and Delmarre himself was not ready to give any details till his investigation was complete. And even if Delmarre had completed his work, how would we deal with the matter afterward? How does one deal with hostile human
beings? I don't know. From the beginning, I felt we needed an Earthman. When I heard of your work in connection with the murder in Spacetown on Earth, I knew we needed you. I got in touch with Aurora, with whose men you had worked most closely, and through them approached the Earth government. Yet my own colleagues could not be persuaded into agreeing to this. Then came the murder and that was enough of a shock to give me the agreement I needed. At the moment, they would have agreed to anything."
Gruer hesitated, then added, "It's not easy to ask an Earthman to help, but I must do so. Remember, whatever it is, the human race is in danger. Earth, too."
Earth was doubly in danger, then. There was no mistaking the desperate sincerity in Gruer's voice.
But then, if the murder were so fortunate a pretext for allowing Gruer to do what he so desperately wanted to do all the time, was it entirely fortune? It opened new avenues of thought that were not reflected in Baley's face, eyes, or voice.
Baley said, "I have been sent here, sir, to help. I will do so to the best of my ability."
Gruer finally lifted his long-delayed drink and looked over the rim of the glass at Baley. "Good," he said. "Not a word to the Auroran, please. Whatever this is about, Aurora may be involved. Certainly they took an unusually intense interest in the case. For instance, they insisted on including Mr. Olivaw as your partner. Aurora is powerful; we had to agree. They say they include Mr. Olivaw only because he worked with you before, but it may well be that they wish a reliable man of their own on the scene, eh?"
He sipped slowly, his eyes on Baley.
Baley passed the knuckles of one hand against his long cheek, rubbing it thoughtfully. "Now if that - "
He didn't finish, but leaped from his chair and almost hurled himself toward the other, before remembering it was only an image he was facing.
