“Well, it wasn’t five minutes later that I could hear them arguing. I tried not to listen as I got the robot – Caliban – off the test stand and started working on him. But voices carry in that building. I think the fight was over the timing of the announcement of New Law robots, and whether it should be immediately connected with the Limbo Project. I had certainly heard enough about that, from both sides, on previous occasions. I didn’t pay much attention.
“Fredda was concerned that a simultaneous announcement would tie the whole New Law concept too closely to the Settlers in the eyes of the Spacers. Tonya refused to see why or how that might be a problem. Fredda wanted to announce the New Law concept first, let people get used to it, and then let it be known that the New Law robots were moving from the labs here into actual productive labor, on the Limbo Project, safely distant on the island of Purgatory. Tonya insisted on her way, disclosing everything at once. I think she felt that there simply wasn’t time to be wasted on the delicate feelings of the Infernals.
“Well, you saw who won that argument, and you saw the results last night. Tonya finally convinced Fredda by threatening to pull the Settlers off the planet altogether. I doubt she was serious, but Fredda had to take it seriously. If you knew how bad the ecological situation was –”
“I do know,” Kresh said. “I was briefed by the Governor.”
“Ah. Well, then. You can see why Fredda felt she could not take any chances. She gave in, but there was a great deal of bad feeling between the two women in any event. It was not the first time Tonya felt she was forced to threaten Fredda with a Settler pullout. Later, she did tell me it would be the last time she’ d have to do that to Fredda.”
Kresh looked surprised and leaned forward in his chair. “Did she indeed?” All of a sudden the case against Tonya Welton was looking stronger and stronger. Gubber was a most reluctant witness against her, but even so he was providing some damning information. “Why did she say that?”
“Oh, no, no. It’s nothing like what you’re thinking. She meant that once the announcement was made, it would be too late to turn back. With the Settlers in place on Purgatory, and the New Law robots there on the job, she would have won and there would be no need for such threats.
“Besides, both she and Fredda had gotten tired of the fighting. I think what Tonya really meant was that they had reconciled their differences. The argument that day didn’t end with shouts and slamming doors, but with quiet voices. You couldn’t hear them at the end. I had the door to my lab open so I could ‘accidentally’ run into Tonya when they were done, without arousing suspicion. But even with my door open, I couldn’t hear them. When Tonya came out with Ariel, I sort of drifted over to the door. I could see that both Tonya and Fredda looked a bit drawn and weary, but they shook hands and smiled, as if they had finally pounded out an agreement they could both live with.”
“What was the agreement?” Donald asked.
“I think it was something along the lines of Fredda letting Tonya have her way with the announcement, in exchange for Fredda heading up recruitment for Limbo. They will need a lot of people out there, and choosing the staff will be a complicated matter. Fredda wanted control of it so that she could surround her New Law robots with Settlers and Spacers who would be able to deal with them.
“Anyway, Fredda said her goodbyes at her doorway and said something about having to get back to her inventory problems. Some serial number didn’t jibe or something. Fredda can be very compulsive about details. She closed the door and Tonya came into my lab. She told Ariel to leave and come back later. That told me that she wanted some real privacy. Tonya is funny that way – she doesn’t really feel private if there are any robots around.”
Gubber Anshaw shifted uncomfortably in his seat, and seemed, unwilling to say more. Alvar Kresh would have been able to guess the cause even without his police training. But just because he knew the answer for himself, that did not mean he did not need Gubber to speak the words. Gubber needed to know that Alvar Kresh needed to know all the details, and would settle for nothing else. Otherwise, Gubber Anshaw could easily get the idea it was all right to leave out other details Kresh did need.
“What happened then, Gubber?” Kresh asked gently. “Why was it that Tonya wanted privacy?”
Gubber cleared his throat and turned his gaze back toward that featureless patch of wall, something approaching a defiant glint in his eye. “I ordered all the staff robots to leave us alone and we went to the duty office at the end of the hallway and made love,” he said, his voice firmer than it had been.
“I see,” said Alvar, more because Gubber seemed to expect him. to say something than for any other reason. Alvar supposed that Gubber thought he might be shocked. The only strong emotion Kresh felt was an overwhelming desire to kick himself. He should have seen it! It was so obvious. The skilled orders for all the lab robots to go away on repeated occasions should have told him what was going on. And who but someone of Gubber’s skill would have been able to hide those orders so perfectly? So much for Tonya Welton’s theory that it had been done with hardware, with microcircuits. That had been a blind, a false lead, of course. Kresh wondered what other smoke she had blown in his face. He was tempted to pursue all those questions, but none of it mattered now. After this was allover, perhaps he could waste time tidying up loose ends.
Kresh looked thoughtfully at Gubber Anshaw. The man was deeply embarrassed. Knowledge of Gubber’s personal relations didn’t bother Alvar, but he could understand Gubber fearing it might. Inferno was not a particularly straitlaced sort of place, but more than a few Infernals would not approve of such an intimate encounter between one of their own and a Settler – especially in a place of business. “So, anyway, the two of you went to the duty office. Go on from there.”
“There was nothing crude or unseemly about it,” Gubber Anshaw went on, seemingly determined to answer objections that had not been raised. “It’s not as if we dumped everything off one of my work counters and, ah, well, did it with the doors open. We went to the duty station office at the end of the hallway. It’s set up to allow someone to spend the night at the lab if an experiment requires it. Do you know where it is?”
“Yes,” Alvar said, struggling to keep a straight face. “We used it the next morning to perform our initial interrogations. I seem to recall there was a full bed in the corner of the room. I thought at the time that was unusual. We have a room like that in my office, but we manage to get by with just a sim~pIe cot.”
Gubber Anshaw reddened violently, and clenched his knitted fingers together so tightly that the skin at the base of his fingers turned quite pale with the pressure. He cleared his throat awkwardly and went on. “Yes, well, there it is, you know,” he said, somewhat enigmatically. “In any event – we, ah, were, ah, there for at least two or three hours all told. Not that we, ah, well, you know, all that time. We talked and visited. We get so little time together.”
“I see,” Kresh said again, encouragingly.
“Well, I suppose it’s quite obvious that this wasn’t the first time we had been together at the lab. It might sound odd, but it was the safest place for us. I stick out like a sore thumb if I go to her at Settlertown, and Tonya is a public figure. My neighbors would be bound to spot her. At the lab, there was the cover of official business. People tend to work on their own there, so there really wasn’t that much risk of, ah, being caught. At any event, our usual arrangement was for Tonya to leave first.”
“Is that what happened that night?”
Gubber thought for a minute. “Yes, yes, it was. I remember because, just when she was about to go, we could hear Jomaine in the hallway. He lives just by the lab, you see, and he’s forever going back and forth at odd hours. I heard him call something to Fredda.”
“Did you hear her answer back?” Kresh asked, trying not to make it sound like the vital question it was. They had the access recorder data, confirming Jomaine’s statement that he had entered and exited the building within a
space of ten minutes. The interesting point was that those ten minutes took place right dead smack in the period of time during which the attack took place, according to the medical evidence.
Now here was Gubber confirming Jomaine’s statement as well, down to Jomaine calling out – though Jomaine had claimed he had called out to see if “anyone” was around. Gubber had him calling out for Fredda specifically. If Gubber had heard Fredda reply at that moment, the period when the attack could have taken place would be chopped in half.
Anshaw thought for a moment. “No, no, I didn’t,” he said. “But I wouldn’t expect to, you know. Jomaine was in the hallway, which is rather echoey. But if Fredda was in one of the labs – hers or mine – at that point, I doubt I would have heard her if she answered in a normal speaking voice. I could have heard her if she was yelling at the top of her lungs, but I wasn’t likely to otherwise. All I heard was Jomaine’s voice calling out that one time.”
Kresh kept his face expressionless, but damn it, this case never got any clearer. The time limit wasn’t reduced.
“All right, then. You heard Jomaine come in, call to Fredda, and then what?”
“It sounded like he entered his lab. We waited for a bit, then when we didn’t hear anything more, we decided he must have left by one of the exterior doors in his lab. We said our goodbyes and Tonya left first, as usual. Then, urn, well, I’m afraid I dozed off.”
“For how long?”
Gubber shook his head. “I’m afraid I can’t really say. Ten minutes, forty-five minutes, perhaps longer. It had been a dead-flat-exhausting day even before Tonya showed up. When she left, and I had nothing to do but lie back in a bed in a dark, quiet room until the coast was clear – well, why not take a nap? It was not a very restful sleep. I had rather disturbing dreams, all about Fredda and Tonya fighting and bickering, with me caught in the middle, taking all the blows whenever either of them struck at the other. After a while, I woke up, used the duty office refresher, and got dressed.
“I stepped out into the hallway and walked over to my lab to collect my things and go home.”
Kresh leaned in eagerly, no longer able to pretend that this was routine, mere confirmation of other information. What Gubber Anshaw could say about what he saw and what he did could break the whole case open. Even if he was lying, his statement would be useful, for sooner or later they would be able to trap him in that lie, and the nature of his lie could help to guide their inquiries. “All right, then,” he said. “Now I want you to be as careful and detailed as possible. I want you to tell me everything you saw. Everything. Don’t leave anything out.”
Anshaw looked at Kresh rather nervously. “All right,” he said. “All right. Let me think carefully. The first thing that I noticed was that the door to my lab was closed, though I normally leave it open. That struck me as slightly odd, but not greatly so. We are in and out of each other’s labs in the course of a day. Someone could have come ill looking for me and closed the door out of force of habit on the way out.
“I walked down the hallway to my door and opened it, and then I saw – saw it.”
“What, Anshaw? What, exactly, did you see?”
“She was lying there on the floor, passed out cold, the robot out of the test rack, standing over her, the robot’s arm raised like this.” Gubber held his left arm out in front of him, elbow bent about halfway, his palm open, arm and hand both held parallel with the side of his body.
But Kresh was not paying attention to details of how Caliban had held his arm in front of him. Burning devils in deepest hell. Gubber was saying Caliban had still been there! Never in a hundred years had he expected that. It made no sense. No sense at all. If Caliban had committed the attack, why was he still standing there? If he had not, why in the world had he vanished later?
“Hold it a moment. Caliban was still there?”
Gubber looked up in surprise. “Why, yes, of course. I thought you knew that.”
“We have, ah, several variant versions of the crime scene.”
“Might I ask if Caliban was operational?” Donald asked. “Was he powered up and functional, or still switched off?”
“Ah, neither, actually. I must admit that he was not the first thing I thought of. I did not take a close look at him. Naturally my first instinct was to look at Fredda. I could not tell if she was dead or alive. There was a small pool of blood just beginning to form under her head.
“Naturally I was scared to death. I was still a bit muzzy from my nap, and my dreams about the two women fighting were still mixed up in my head. I assumed that it had to have been Tonya who – who did it. I was standing over Fredda, next to the robot, wondering what to do, when I heard the robot’s functionality confirmed tone code.”
“His what?”
“It’s a tripled triple beep. Beep-beep-beep, pause, beep-beep-beep, pause, beep-beep-beep. It’s one of a sequence of tone codes a gravitonic brain robot makes as it powers up. One of the minor drawbacks of the gravitonic brain is that its initial power-up sequence takes about fifteen minutes to an hour, rather than the two or three seconds of a positronic unit. We ought to be able to; reduce that delay in the next generation of brains, but –”
“Hold it, hold it. Let’s not worry about the next generation of brains just now. Let me understand this. You heard this tripled triple tone coming out of Caliban, and that tone indicated he was in the process of coming on?”
“Yes, that’s right.”
Incredible. How could they have missed it? Caliban had been turned on for the first night. They had accepted that without ever asking the burningly obvious question – by whom? Damnation! Gubber Anshaw was supposed to supply new answers, not new questions. “All right. What happened then?”
“I left. I grabbed the things I had meant to collect when I went into the lab and I left.”
“What? Your friend and superior dead or unconscious on the floor and you leave?”
Gubber dropped his head down to stare intently at his hands. “I’m not proud of it, Sheriff. But it is what happened. The tripled triple tone told me that the robot there would be fully activated in another two minutes. I had no reason to think he was anything other than a standard Three Law unit. Gravitonic robots can take the Three Laws or New Laws just as effectively, and there is a standing lab policy to keep all New Law robots under very strict control. If Caliban had been Three Law, then Fredda Leving would have received first-aid attention within 120 seconds – and far better care than I could offer. And there would be a witness there – a robot witness but a witness all the same. to report that I had been there when the attack happened. I had nothing to do with it, I swear it. Neither did Tonya or Jomaine. I realized that later.”
“How do you know that?”
“Fredda’s tea mugs.”
“I beg your pardon?”
“Fredda drinks her tea from rather large and fragile mugs that some artist friend of hers makes. Fredda is forever forgetting they are not as strong as standard containers. She’s careless with them. They fall and break frequently, and when they smash into the hard floors of the lab, you hear it everywhere in the building.”
“What’s that got to do with anything?”
“There were the remains of a broken mug on the floor of the lab. I heard both Tonya and Jomaine in the hallway. I heard Tonya leave, and both she and I heard Jomaine leave the hall and go into his own lab, down the other end of the hall. He never came back down it, and the exterior doors to the labs lock from the inside, so he could ‘only have gotten into the building through the main entrance. I heard all that.” Gubber looked up, glanced from Kresh to Donald and back again before he went on.
“Now, I suppose someone could strike someone else over the head without a lot of noise. Maybe I would have missed that. But I was listening carefully when both Jomaine and Tonya left and I never heard the cup smash against the floor. It must have happened when I was asleep. I’m a deep sleeper, and as I said I was exhausted. Either I slept right through it,
or else I incorporated the sound into my dream about the two women fighting. Perhaps that crashing noise even set that dream in motion.”
“Forgive a most awkward question, sir,” Donald said, “but is it possible that you might have missed the crash if it had happened earlier, when you and Lady Leving were together in the duty office?”
Gubber glanced up, beet-red, plainly embarrassed. “Ah, well, yes,” he said. “There were certainly times in that period when we would not have heard anything.”
“One other question, sir,” Donald went on. “Can you characterize any marks or things you might have noticed on the floor of the room?”
“I’m sorry?”
“You said you saw the smashed mug and the blood pooling under Dr. Leving’s head. Was there anything else of note?”
“Oh, I see. No, not that I noticed. But I can assure you that I was not in much of a state to notice anything at all. The moment I heard the tone code coming out of that robot, there was nothing on my mind but leaving. I doubt that I was in the room more than thirty seconds at most.”
“This tone code,” Kresh said. “You said it was part of the robot’s wake-up sequence, and that it indicated how long until the robot would come on. Can you tell us how long before that tone the robot would be switched on?”
“Not without knowing a great deal more about how that unit was configured. There are three or four brain types, gravitonic and positronic, that can be installed in that body type, and there is other equipment that can add variation. The size and type of the on-board datastore, for example. It could take anywhere from fifteen minutes to an hour to go from a cold gravitonic robot to a tripled triple.”
Damnation. Events seemed to be conspiring against solving the case. Each new bit of information seemed only to muddle the time sequence or confuse the issue. Kresh felt he would go mad if he did not come up with some sort of witness, and it seemed there was only one potential witness left. “Is there any way that Caliban would have been aware or operational before the moment you came in?” he asked.
