He was right. He heard the slap of a hand against the door switch and the faint whine of the door motor starting up. At the swish of the door opening he was already flattened against the wall a few feet to the right of the arch, hands ready to chop, knees slightly bent for a spring. As the door opened wide enough for the two guards to dash through, swords drawn, he moved.
He took one guard out with a kick from the rear that sent him flying halfway across the chamber before he hit the floor and slid the rest of the way into the empty tub with a thump and a clatter of weapons. The other guard had time to turn around and raise his sword. but he made the mistake of raising it for a slash and not relying on a quicker thrust. Blade's flattened hand chopped him across the throat before the sword started down; he choked, started to crumble, then Blade kicked him in the stomach and he shot backward and joined his late comrade in the tub.
Guard number two had dropped his sword as he fell; Blade picked it up and wedged it in the door track to keep any casual passerby from closing the door and locking him in the room. Then he went over to the tub and began stripping the two guards of their clothing and weapons. Neither was quite as large as he was, but he found the larger one's trunks and boots fit him without too much discomfort or restriction on his movement. Fortunately the guards wore no distinctive hair styles, tattoos, or other recognition marks; this made his job of disguising himself as one (at least well enough to fool the Menel) comparatively easy.
Now came the second risky part-disposing of the bodies. They had to disappear without a trace, both to demoralize their comrades more effectively and to prevent their being found where they might cast suspicion on Blade. The nearest disposal chute large enough to take the bodies was some fifty feet down the corridor. He slung the first body over his shoulder, stuck his head out to see if the corridor was clear, then hurried down to the chute opening and pitched the body in.
If anybody came by now, he would have to kill them and send their bodies after the guards. Down at the bottom of the chute lay the waste disposal chambers where the organic and non-organic wastes were separated, to be recycled respectively for algae cultures and building material. He hoped nobody would appear. Apart from the possibility of somebody getting away to give the alarm, too many killings too soon might weaken the regular guards enough to give the Menel-conditioned ones a fatally large edge.
Nobody came. He disposed of the second body, went back to his chamber, picked up the sword, and hung it on his belt. He checked the chamber to make sure it looked normal, then went out and closed the door behind him. Now it was time to prowl! He headed down the corridor toward the elevator that would take him down to the slave level. His first goal had to be the head of the shaft to the Menel colony and then-well, he would see.
He met two guards escorting four slaves as he approached the elevator entrance; a late working party being led back to their quarters, no doubt. He hoped his disguise would hold. The slaves would hardly help the guards, but they might very well panic, scatter, and unintentionally give the alarm that something unusual was afoot.
The guards came stamping along, passed abreast of him, turned to look at him, then turned away again and back to their charges. Blade's breath whistled out in relief so loudly that for a moment he thought the guards must have heard it. Not for the first time, he thanked the Ice Master for conditioning curiosity out of his guards along with so many other «individual» qualities.
He fell in behind the little group and kept pace with them, matching his stride and manner to the guards', all the way to the elevator. They all got in and the door closed behind them, then the lift sank silently into the depths. In the two minutes it took the elevator to drop down to the slave level, neither the guards nor the slaves took any further notice of Blade. As long as he possessed enough of the outward signs of being a guard not to trigger any of their conditioned warnings, he was apparently going to be safe-at least until he went into action. And then the rapidly spreading chaos should hopefully leave the slow, conditioned wits of the guards laboring along far in the rear.
The elevator stopped and the door whispered open. The four slaves trotted dutifully out, the guards now flanking them, Blade following behind. They turned left, toward the slave quarters; Blade turned right, toward the head of the shaft.
He was not entirely certain what he could do to get the Menel to notice him and come up into the stronghold. Dropping in on them-literally-by going down the shaft would be nothing but a swift way of committing suicide, he suspected. They almost certainly would have warning systems or sentries at the bottom, and if anything unexpected came down it, they would probably cut the gravity control off and let it drop. No doubt there were also barriers against bombs, gas, etc.-so if the problem had involved physically attacking them it would have been almost insoluble, apart from the fact that he wanted to inflict as little damage as possible in the process of calling himself to their attention.
However, annoying them, like a mosquito whining around a man's head until he tries to swat it, might prove simpler. From his pouch Blade pulled out one of the Ice Master's ultrasonic grenades, microminiaturized generators used in herding the Ice Dragons. Then he pulled out a timing device, also lifted from the laboratory storage shelves. Hooked to the grenade, it would delay the firing for as much as twenty minutes, long enough for the grenade to sink well down the shaft before giving off a two hundred-decibel blast of ultrasonic sound. That, Blade was fairly certain, would register on any detectors or warning systems likely to be down there, possibly wreck them, and certainly alert or alarm any Menel sentries. Since the sound grenade was a device the Menel themselves had given the Ice Master, they would be more than likely to demand an accounting for such an unorthodox, not to say hostile, use of it.
He wired the timer to the firing mechanism of the grenade and strode over to the head of the shaft, hefting the grenade in his hand. It was no larger than a small pear, but weighed more than four pounds. He reached the edge of the shaft-and halted in mid-stride.
Unmistakably there was a current of air rising up the shaft-he could see dust particles soaring upward, glinting in the light-and unmistakably that rising current also bore with ever-increasing strength the damp, moldy odor Blade had noticed previously clinging to the rim of the pit. For a moment he froze in place, nearly paralyzed with surprise-and not quite able to suppress a little fear-then sprang backward; looking for a place of concealment.
As he did so the lights began to blink on and off in a well-defined pattern-three long blinks, three short blinks, two long blinks, two short blinks, then start the cycle over again. A high-pitched whine that wavered uncertainly for a moment, then settled down to a regular undulation, started hammering at his ears.
Two guards came out of the corridor that led to the slave quarters. Blade started, spun ready to strike, then stared as he saw them slow, stop, and finally stand motionless as statues, their arms at their sides and their eyes staring vacantly into space. Of course! The Ice Master wanted to keep the existence of the Menel a secret from his servants and slaves, so part of the conditioning was designed to put them into a trance whenever the lights and sirens that signaled the approach of the Menel went into action. And Blade was certain that the updraft and odor from the shaft could mean nothing else but the approach of the Menel. He found himself sweating as he contemplated being the first human being to face a non-human intelligence. It was nearly tragic that this contact was bound to be somewhat hostile-but what choice did he have for the moment, other than abandoning the human population of this planet?
