And he had always treated Dr. Fredda Leving, his patron, his creator, with the greatest deference and respect. Caliban had always done her honor.
He would not put all that on the line lightly. Caliban would not lie in the creator’s name.
“Caliban is to be trusted,” he said at last. “He means what he says, and he can do what he believes he can do.”
“Thank you, Governor. I believe you, and believe you are correct. Please stand by.”
There was a brief pause, and then the unison voice, Unit Dee and Unit Dum together, spoke together once again.
“Initial phasse of prre—programmmed terminal approach will commmennce in one hourr, twwwenty-two minutesss,” they announced.
Kresh started breathing again—which was the first that he realized he had stopped. It was going to happen. It was going to happen exactly as Davlo Lentrall had said it would, two months and a lifetime ago.
Now all they had to get through was a dozen massive comet fragments smashing into the planet.
THEY HAD NEVER found Valhalla. Now, unless they were bothering to track this aircar right now, they never would.
Caliban took back the controls as the aircar came up on the target area. There it was, down below: Loki Lake. It was one of a hundred, a thousand tiny lakes that dotted this part of the landscape, each exactly like all the others. And yet Loki was utterly different from all the others. Everyone had always focused on the notion that Valhalla was underground—and so it was.
But it was also underwater.
Caliban pulled the aircar around into a hard, tight turn and pulled the nose up. The area was full of hidden landing pads, camouflaged repair centers, and underground bunkers that could hide any number of aircars from view. None of that mattered anymore. Let every satellite that orbited the planet spot his aircar landing here. Three hours from now none of it would still exist. Caliban dropped the aircar down right by the shores of the lake. He retrieved the blaster from the side compartment, and rummaged around in the aircar’s storage compartments until he found a watertight container that the gun would fit into. He dumped the contents of the container, put the gun in it, and sealed it up again. In all likelihood the blaster would not be at all bothered by immersion—but this was no time for taking needless chances. He put the container under one arm and got moving.
Caliban opened the outer hatch of the aircar and stepped outside. It was almost full dark now, and he switched over to infrared in order to see better. There, at the shoreline, he noticed two more pieces of evidence that he had guessed right. There was a camouflaged aircar hangar, designed to conceal whatever vehicles were in it from airborne detection. But one could see into it perfectly well from ground level. In it was an aircar he recognized. Caliban looked toward the nearest service rack and noticed that one of the larger personal cargo rollers was missing from its storage slot.
That was not good. It was all exactly the way he had figured it would be, but none of it was good. He could not remember a time when he had been less pleased to be right. He turned and headed directly for the shoreline. There were many other ways in and out of the city, but this was the main entrance.
The walkway was exactly the same color as the belt of shore sand it led through. It was well camouflaged enough that it was hard to see, even from ground level. From the air it was utterly invisible. But for all of that, Caliban found it easily enough, and started to follow it as it led along the lake shore—and then down under the water itself. Ankle-deep, knee-deep, waist-deep, chest-deep, he walked out into the lake, until, at last, he was completely underwater.
People float. Robots sink. A robot could walk along the path Caliban was on, having to move somewhat more slowly underwater, but with no other real problems. A human would bob to the surface. A human wearing sufficient ballast and carrying breathing equipment could have walked that path, but not easily. But the main advantage of the under-lake entrance was that it would simply not occur to the average human that anyone would put an entrance there.
Caliban kept going, moving deeper and deeper underwater. At last he came to the complex of airlocks that made up the main entrance to the city of Valhalla. He picked the closest personnel locks, by the cargo-lock section, and cycled through, sealing the outer door behind himself, and waiting for the pumping system to pull the water out of the chamber and bleed in air from the city interior. At last the inner door opened, and Caliban stepped through.
There it was. He had expected to find it there, but he was not pleased to do so. The large personal cargo roller, in essence an airtight box that could be pulled along by the tow bar attacked to the front. The cargo roller was about the size and shape of a steel coffin on wheels—not the most happy comparison that could have sprung to mind. Caliban looked inside the steel box. Yes. There it was. An airtank with a breathing mask, and a carbon-dioxide scrubber as well. It all made sense. After all, the kidnapper could not harm his victim.
But time was short. Caliban took his blaster from its waterproof container and held in his right hand as he kept moving forward, out of the airlock complex and into the main corridors of the underground city. He thought he knew where to look for Beddle, but he could not be certain. It might be that he would have to search a fair part of the city before he found the man. He would have to work quickly.
He found the first of the murdered New Law robots just a few hundred meters from the airlocks. The body was sprawled face down on the floor of the corridor, shot through the back of the head in much the same way as the victims at the aircar site. Caliban knelt down next to the body and turned it over. It was Lancon-03, Prospero’s most recent protégé. Lancon, it would seem, had gotten in somebody’s way.
But there was nothing Caliban could do for Lancon now—and time was short. He had to keep moving. He spotted three more murdered New Laws as he walked along. There had been nothing but a few caretakers left behind in the city to deal with last-minute details. It would seem that the kidnappers had dealt with all of them.
Each should have been mourned over, praised, remembered—but time was short. Caliban broke into a trot, hurrying forward through the sterile emptiness of the depopulated robot city. Every tidy, immaculate, sensible, utilitarian, carefully laid-out passage and street and building now was meaningless, useless. The empty town of Depot had seemed like a place that was dying, lost, abandoned. Somehow, the empty town of Valhalla seemed like a place that had never lived in the first place. Caliban thrust such thoughts from his mind and hurried on up the ramps to the upper level, the huge half-cylinder-on-its-side that was the main gallery of Valhalla. He jogged up the central boulevard and into the main administration building of the city. He slowed, and moved more cautiously up the broad, sloping ramp that led to the building’s upper story and the executive offices there.
And suddenly Caliban heard a voice. A human voice. Beddle’s voice. He tried to make out the words as he got closer. At first, he could only understand a word here and there. “—ever you want to know… promise you that—” He moved in closer, until he was right outside the door, and then he could hear it all. “I will make any promises you like, and put them in writing,” Beddle said. “Just let me out of here. You have convinced me that your cause is just. Let me leave, and—”
“If I let you leave, you will prove yourself a liar,” another voice said.
