City Of The Living Dead

Chapter 8

They climbed in as nearly a straight line as they could manage. Blade wanted to get high above the plain and well out of bowshot before the second party of pursuers caught up with them.

This stretch of hillside was steeper than most and also booby trapped with loose slabs of rock. In spite of the occasional falls and scraped skin, Blade was happy about the difficult slope. The Shoba's heavily equipped soldiers would have a slow and painful time tackling the hillside. In the process, they would make fine targets of themselves for a man waiting above with a bow and a large supply of arrows.

This hill was also higher than usual-in fact, it almost deserved the name of mountain. The base of the Wall was nearly half a mile above the plain. Long before Blade and Twana reached it, the Shoba's men had ridden up to the foot of the hill. After they'd proved to their own satisfaction that they were out of range, with a few useless musket shots and arrows, they settled down to wait. Blade felt a moment's temptation to thumb his nose at the enemy. They would have a long wait for him and Twana to come down. The temptation vanished swiftly as he looked upward to the endless grim Wall that loomed steadily closer with each step they took.

At last there was no more upward slope in front of them. Far below the Shoba's men looked like ants crawling about on the plain. Directly above them rose the Wall, so close that Blade could reach out and touch it. The blue-gray material was cold, as hard as metal, and faintly rough to the touch, like fine sandpaper. Here and there in the blue-grayness, Blade could see faint swirling patterns, but he could see no seams or cracks. The technology that had built the Wall was certainly far ahead of Home Dimension. More than ever, Blade was curious to see what lay beyond the Wall. What would the builders have considered so valuable that they would build this Wall along a hundred or more miles of hill crest to protect it? Or what danger was so great that the Wall was needed to guard against it?

All along the base of the Wall, shrubs and vines crept upward in thick, tangled clumps, as if the presence of the Wall made the soil at its base more fertile than elsewhere on the hills. Blade and Twana started north, while Blade looked for a vine or tree strong enough and tall enough to carry him to the top of the Wall. Twana kept an eye out for the Watchers. She was pale and moved with little jerky steps, as though she expected the Watchers to rise out of the ground in front of her at any moment. But she was also alert and kept up well.

In an hour they'd left the Shoba's men out of sight in the haze and mist to the south. Twana was beginning to mutter, «Where are the Watchers?» Blade would have liked an answer to the same question. Here they are, marching steadily along the very base of the Wall, without the faintest sign that the Watchers even existed. If the legends were entirely true, they should have been dead by now.

Somebody else had risked the Watchers, a long time in the past. Blade saw a place where at least a ton of gunpowder must have been set off against the base of the Wall. The rock was split and shattered, and a blackened hole revealed several feet of the Wall's foundations. The Wall itself showed a faint discoloration and some barely visible pitting, but otherwise the explosion had left it completely unaffected.

Another hour's walking brought Blade and Twana to a stretch of Wall three hundred yards long and completely overgrown with massive vines from ground level all the way to the top. A six-year-old child could have scrambled up those vines, let alone a trained athlete like Blade, who had climbed the face of the Eiger.

He went up carefully though. He weighted a good deal more than any six-year-old child. If the vines did break under him, he might be dropped forty or fifty feet onto hard rock.

A broken leg here and now could be a good deal more fatal than the Watchers.

Foot by foot, Blade clambered upward. In places his fingers pushed through the tangle of vines and touched the Wall itself. When he did that, he could feel a faint, irregular vibration within the blue-gray material. It was like putting his fingers on the head of an enormous drum being gently tapped by an invisible drummer. Once he was able to put his ear against the Wall and hear a distant humming that came and went in irregular pulses. The Wall was not as dead as it seemed, or perhaps even as solid.

The last few feet were particularly tricky. The vines were growing thinner, the twice strands broke as Blade gripped them. Both times he hung there with a death clutch on the broken strands, barely breathing, toes curling for a better foothold.

At last there was no more Wall to climb, only a flat surface like a blue-gray tabletop stretching out of sight. The golden shimmering in the air above the Wall was clearly visible now. It seemed to start three or four feet above the top and then curve upward and away toward the inner side of the Wall. It was soundless, odorless, unchanging, and totally unlike anything Blade had ever seen or imagined. It reminded him that, as he explored the Wall, he might be in the position of a caveman trying to examine and understand a jet bomber — or an atomic reactor.

Blade scrambled out onto the top of the Wall. On hands and knees he crawled forward. He held his sword in one hand, probing the featureless surface ahead of him as he moved.

He covered forty feet, and then suddenly he could no longer see. It was as if he'd stuck his head into a black sack. He drew back, startled, and vision instantly returned. He looked ahead, at both the Wall and the air above it. High above he caught hints of the golden shimmering. Directly in front of him, he could see nothing at all except the top of the Wall. He crawled forward-and again the world vanished around him.

He tried three more times, until his head was beginning to spin with the repeated coming and going of his vision. By that time he realized what had to be wrong. The Wall was generating some sort of field that completely deprived him of vision. That field started at a point only a yard or so in front of him and continued until…

That was a question he'd have to answer, sooner or later. Not now though. Not when he had Twana to get back home and the Shoba's men were still close enough to take advantage of any mistakes he might make. He crawled back to the edge of the Wall and stood up slowly. As his head rose into the golden shimmering, he had a moment's sensation of being jabbed with thousands of tiny blunt needles. Then the sensation faded. Whatever the shimmering meant, it did not appear to be dangerous.

Blade tied a loop in the end of the rope and threw the loop down to Twana. She caught it and drew it around her body. Then Blade began to back slowly away from the edge of the Wall, pulling Twana up as he did.

He was also keeping watch on either side of him, along the top of the Wall. It rose and fell in long, slow curves, like waves far out at sea. It was totally bare. In a few places it looked as though it had even been scraped or sandblasted clean.

That thought reminded Blade of the Watchers. He was beginning to wonder if they had ever existed, except in the legends of the village people. Here he was on top of the Wall, and he still seemed to be completely invisible to whomever or whatever might be on guard. He was also perfectly happy with this situation.

As Twana's head appeared over the edge, Blade caught another flash of the sun on polished metal. This one was far to the south and came and went so quickly that he wasn't completely sure he hadn't imagined it. He reached down and helped Twana up onto the level surface. She lay gasping for a moment, then rose to her knees and reached for her water bottle. As she drank, Blade again scanned the top of the Wall in both directions, as far as he could see.

Whatever had made the flash was now invisible again. A Watcher? A large metal machine such as Twana had described could make the kind of flashes he'd seen when the sun caught it at the right angle. If the Watchers existed, that is-and if they existed, then where were they?

Blade and Twana moved swiftly north along the smooth top of the Wall. They went barefoot to reduce noise and leave no visible traces. They kept just far enough away from the edge of the Wall to be invisible from the ground without wandering into the blindness field. If the Watchers no longer mounted a reliable guard on the Wall, the Shoba's men might also discover this. Then they might be willing to climb the hills, and the chase would be on again.

Blade decided that he and Twana would stay up on the Wall for two days, moving as far as they could in that time. That should leave the Shoba's men far behind. With the enemy off their trail, they could return directly to Hores. Blade was no longer quite sure what he'd be doing after that. This Dimension was developing more than the usual quota of mysteries. The Wall seemed to be only a starting point.

They'd been walking for two hours when Blade saw metal flash again, three times in five minutes. The flashes were a good ten miles away, but this time they were to the north. He stopped and desperately strained his eyes to see what might be waiting for them but saw nothing-not even a hint of movement.

After a few minutes they moved on. Blade no longer felt quite so willing to believe that the Watchers were a myth. It occurred to him that they might be playing games with him, like a cat with a mouse, waiting for their chosen moment to strike.

They walked along the Wall all through the rest of the morning and into the afternoon. Every hour or so Blade went down on his belly and crept to the edge of the Wall to examine the plain below. The Shoba's men were nowhere in sight.

Blade decided that, if their pursuers were still out of sight the next morning, he and Twana would climb down from the Wall and take to the ground again. It would be a gamble, but he was beginning to feel it would be less of a gamble than staying on the Wall. Blade had almost a wild animal's instinct for detecting danger, and that instinct was now sending him a clear message. They told him that the Wall was protected by Watchers or by something that was waiting, invisible for the moment, but able to turn deadly dangerous in the blink of an eye.

Midafternoon now, and the sky was growing cloudy. There would be no more reflected sunlight to give warning of whatever might be lying in wait for them, at least not today. Before long the sky had turned gray, and a premature twilight began to spread across the land. Blade and Twana stopped, drank without eating, and went on. Fatigue and strain had bleached Twana's face to the color of bone, and her feet were swollen and blistered. Yet she still seemed quite ready to follow Blade to the end of the Wall, or even farther.

Suddenly Blade heard a faint hooting, like the sound of a distant owl. It came from ahead, but a moment later it was echoed from behind them. Blade stopped and drew his sword. Twana pressed herself against him for a moment, then stepped back, drawing her own sword and standing to guard his back.

The hooting came again, from both in front and behind. It was either louder or closer or both. Then it came a third time. The cat had finished watching the mouse. Now it was stalking. In another moment it would leap. Blade was not sure exactly what the cat would be, but he suspected it would be something against which a sword would be as useless as a feather duster.

The hooting came again, still louder, with a distinct metallic note in it. No living throat could be making that sound. Blade sidestepped toward the edge of the Wall. With only a minute or two more, he could let down the rope to make an escape route for Twana. He himself would probably have to ….

Then the hooting was echoed from close at hand, so loudly that the Wall seemed to quiver from the sound. There was a rushing and roaring of violently disturbed air from beyond the blindness field. A blast of wind hit Blade and Twana, hard enough to force the girl to her knees. Something that seemed to be the size of a small house shot high into the air from inside the Wall. It hung in the air above Blade, long enough to give him a grisly moment's anticipation of being crushed flat under it. Then, with another hurricane blast of air and a ringing metallic crash, it came down on top of the Wall.

Twana's mouth fell open, and she gave a gurgling scream of sheer terror. «A Watcher!» she cried. Her sword was shaking in her hand, but somehow she held her ground.

Blade's mouth was open in surprise rather than fear, although he didn't blame Twana. He stared at the Watcher, and from what he had to call its head, two yellowish eyes stared back at him.

The rest of the Watcher-well, start with a rectangular metal box the size of a small truck, set on end. Put the dome-shaped head on top of that, with the eyes, half a dozen antennae, and the twin glassy-blue muzzles of what looked very much like lasers or guns. On each side of the box, stick two arms-the upper one a pair of long, jointed rods ending in massive steel claws, the lower one an eight-foot steel tentacle. Mount the whole thing on a circular base ten feet in diameter. Color it a dirty bronze-tinted blue all over, and add a few dents, patches, and scars.

That was a Watcher, as Richard Blade faced one for the first time on top of the Wall.

He could hear Twana's breath coming in quick gasps, and he didn't blame her. Even if one hadn't gone in fear of the Watchers all one's life, they weren't a pleasant thing to meet. Particularly when there wasn't much hope of either fighting or running.

Those weren't the only choices, fortunately. This machine had to be the creation of an advanced civilization. If its masters were watching through its eyes and listening through its ears, perhaps there was a way to communicate with them. Certainly it was worth trying.

Carefully Blade laid down his sword. Then he straightened up, holding his empty hands well out from his sides, fingers spread wide. If the Watcher's masters were humanoid, the gesture should have its almost universal meaning of «Peace.» Then he whispered sharply to Twana, «Do the same as I've done.»

«Blade, I-«

«Do it!»

He heard Twana suck in her breath with a hiss. Then at last her courage deserted her, and she turned and ran. Before she'd taken two steps, the Watcher let out another ear-splitting hoot, rose a foot off the ground with a whine and a blast of air, and started after her. All four arms were raised, and both eyes were blinking rapidly.

Blade threw himself to one side, just in time to save his life. A beam of dazzling white light flared from one of the blue muzzles in the Watcher's head. It played across Blade's sword, and when it passed on, it left the metal blackened and warped.

As Blade sprang to his feet, the Watcher's arms on the side toward him lashed out. The tentacle whipped around his knees, while the claw on the upper arm unfolded until it could span his waist. Blade was jerked off his feet and into the air, as the Watcher swept by in pursuit of Twana.

The girl screamed as she saw the Watcher gaining on her. Then she stumbled and went down, the sword flying out of her hand. Blade's arms were free. He reached down to the jointed arm that held him by the waist, grabbed the elbow with both hands, and heaved with all his strength.

It should have been impossible, flesh matched against metal in this way, but Blade's strength somehow made it possible. The arm gave with a screech of twisted and torn metal and went limp, pouring out smoke and sticky bluish fluid. Blade found himself dangling in midair, held only by the tentacle around his knees. He tried to swing himself toward the body of the Watcher. If he could get a firm grip there and then start on the joints with the knife from his belt-

He never made it. The head turned toward him, and Blade had a moment of staring into the mouth of one of the blue tubes-a moment just long enough for him to know that he was about to die.

Then Twana screamed again, and the world dissolved around Blade in white fire and terrible pain.
