He caught a glimpse of a blue robe and the darker, overlaid harness of a vacii costume. One withered lizardy leg appeared at the edge of the door from the stairs. They were coming to this floor despite his prayers. Sliding the door open, he went into a lighted room that was much like other rooms he had seen thus far, and slid the portal shut behind.
Zee gee' sa tiss ga', a vacii said, coming from behind a desklike piece of furniture.
Salsbury decided the words did not require an answer, but were some sort of exclamation. Just come to check the air conditioning, he said.
Scee-ga-tag! the vacii said, alarmed.
But Salsbury had taken its attention away from the hand that held the pistol at his side, gained a moment to bring the gun up unnoticed. He fired, forgetting the weapon was still on a machine gun basis, and scattered the beast into a dozen, hideous pieces.
Just then there was a noise behind, the door slid open on its runners.
He danced across the floor, came against the desk, crouched and ready, perspiration flooding down his neck, soaking his clothes. But the two vacii that entered the room had not heard anything. They were talking to each other, and one of them had just begun to hiss what must have been the alien equivalent of a laugh. It was letting air out through its toothless mouth, puckering that obscene hole until the escaping air sounded like a leak in a steam pipe. Salsbury wondered, briefly, what a theater full of these clowns would sound like. Then he had no time for divergent thoughts. The laughing vacii stopped laughing abruptly, sucked air in when it saw Salsbury, grabbed the shoulder of the first vacii
Salsbury fired, caught the first alien in the side, kicking it backwards toward the door jamb. Before he could get a second clear shot to finish that one, the second vacii was gone into the hall, keening a sound that must have carried halfway around this world. There was no doubt it was calling for help.
No doubt it would get what it called for.
Even as he stood there listening to the ugly sound the thing made, Salsbury began to hear other voices shouting in the vacii tongue from points up and down the main hall.
He stepped over the body of the vacii with the weeping, fatal wound in its side and slid the door shut. He looked but could find no means of locking it. Had it had a knob, he could have stuffed a chair under that to keep the thing braced shut, but there was only the recessed handle for fingers to grasp.
With his back to the door, he surveyed the room just as a rat examines its cage in the first few minutes of its imprisonment. The walls were discouragingly featureless but for the crude unfinished nature of them. There were no doors into other rooms, no exits except that which he could not use. He had a sudden gory vision of the vacii pumping slugs through the door from the other side, into his back. He moved quickly away, behind the desk where he could at least make some sort of stand with a minimum of protection. As his eyes finished the scan of the chamber, they stopped on a small, black square set high in the wall, near the ceiling. His heart pounded like a twelve ton piston, and he stepped gingerly over the shattered vacii until he was standing direcdy beneath the hole. Cool air wafted out. A ventilation shaft.
The noise from the corridor grew louder. He could tell there was a group of vacii standing beyond the door, not prepared to open it and face his gun yet, but building up the courage and the fire power to take the chance any moment.
He brought the dead vacii's chair over to the wall, stood on it, bringing the ventilator hole even with his face. He stood on tip-toe, reached into the shaft and levered himself up until his feet were off the chair. He scrabbled with his knees and feet against the wall, tried to drag himself forward with his arms. But he needed something more for purchase. He felt around, stretched his hands and fingers until he found a rugged one-inch shelf in the plaster floor of the shaft. He hooked his fingers over that and pulled, managing to get into the opening to his chest; the ragged edge of the wall cut across his belly, making breathing painful. The way ahead was Stygian and smelled vaguely like the inside of a crypt. He tried to shut off his nose, wriggled forward, kicked with his feet on the edge of the outlet, and sprawled full length in the shaft
The passage was so narrow that he could not kneel to crawl, but could only stretch out flat and belly forward like an infantryman nervously making his way up an enemy-held beach, expecting a barrage of mortars at any time. Ten feet farther along, the light from the other room behind completely blocked by the bulk of his body, he heard the booming of a gun and the door shredding under the vicious cover of fragmenting slugs. They weren't going to enter that room until they were positive nothing could be alive in it. That was just as well, for that gave him more time to make his get-away. If he could. After all, there was no guarantee this shaft led anywhere. It might even narrow to a little pipe far too small for him to squeeze through. Then they could come in at their leisure. Or gas him and drag him out. There were all sorts of unpleasant possibilities,
It didn't narrow, though, and struck inward another fifty feet before ending where two other tunnels branched off, one to either side at ninety-degree angles off the main run. There was also a drop shaft from the floor here to the ceiling of the ventilation level below.
He looked to the left and right, his eyes conditioned somewhat to the darkness so that the tunnels were a dim gray gloom rather than impenetrable pitch. Either way looked equally appealing. Or, rather, equally unappealing. If he went left or right, he would still be on the eleventh floor when the building-wide search was initiated, as it surely would be. But if he went down, he could work closer and closer to the projection room and the portal that linked this probability with his own. True, the plan had developed hitches, but he was not as concerned with the mission now as with saving his own skin. Thank heavens iron Victor was no longer in a position to control him! He left two of the micro-bombs behind and went down the drop shaft, using his knees and hips and shoulders to brace against injury.
One floor after another, tearing skin off his fingers on the rough surface of the tunnel and shredding the knees of his jeans and the shoulders of his shirt, he went down, leaving a trail of bombs behind. It was not as good as distributing them evenly throughout the building, but it was the best he could manage under the circumstances. When he had counted off ten floors and knew he was downstairs, down where the projection room waited, he scrambled back along the main tunnel, looking for an outlet into an empty room.
He found three. Behind the first, in a small, dimly lit room, half a dozen vacii slept in hammock-like affairs slung at varying heights between the rough, alabaster walls. Getting through there would be like trying to plod through a field of porcupines without touching a quill. Sooner or later he would wake one of them, and they would pull the roof in on him. The second and third rooms were both working chambers and had two vacii each. Perhaps he could have aimed his weapon from his hiding hole and killed both of them before they could make a sound, but he did not. Killing vacii was not as physically disturbing as killing a human being; he would not have the traumas from murdering aliens as he had from murdering Harold Jacobi. Perhaps that was a mistaken philosophy, an outgrowth of xenophobia implanted in him by his makers. However, he felt that it was morally the same. He knew his future creators had not meant him to be a wanton killer, otherwise they would have made it easy for him to murder.
