We drifted up the black face of the rock like a slow elevator, sitting ducks for anyone with a good gun and a keen eye. It was uncomfortable to say the least. I had to lift off gradually so our harness wouldn't buckle, but I speeded up as fast as I could until we were on maximum lift. A visible aura of heat began to radiate from the grav-chute as it struggled against all our dead weight. It would be highly uncomfortable if it failed now.
Then deep-cut windows flashed by, happily unoccupied, and the black stone changed to dark wall and the crenellated top of the parapet was ahead. I angled toward it and cut the power completely just before we reached the edge. Our acceleration carried us up and over in a high arc, and after that, things happened at an incredibly rapid pace.
There were two guards on the wall, both surprised, angry, armed, about to fire. But Angelina and I fired first. We were using the needle guns now in order to remain undetected as long as possible. The guards crumpled in silence, their faces and necks suddenly bristly as pincushions, and I hit the power on for the landing.
Landing! There was no courtyard or solid roof below! We were coming down on a domed and transparent cover over a large workship, a canopy made of what appeared to be glass panels held in a tangled web of rusty metal braces. We looked at it, horrified, as we rushed toward it, and I had the power on to the last stop. We groaned at the sudden acceleration, and the harness groaned as well and creaked and bent. The dome was too close, and we were just not going to stop in time.
It was lovely. A silent, secret attack, flitting gray ghosts in the dawn. Six pairs of boots hit at the same instant, and about five thousand square meters of glass were kicked out. The supporting framework twanged and bent, and some of the rusty supports snapped free. For one shuddering instant I thought we were going to follow all the glass that was now crashing and clashing into the chamber below with a hideously loud cacophony. Then the grav-chute gave its all with one shuddering last blaze of energy, halting our forward motion, then burst into flame as well.
"Grab the supports!" I shouted, tearing at the buckles that held the grav-chute to our harness. It resisted, searing my hand, then finally dropped free. Straight down into the hall with its screaming occupants below, where it promptly exploded. I sighed and dropped some smoke and flare bombs as well to add to the confusion.
"Our presence is now known," I said, inching back toward safety. "I suggest we get off this precarious jungle gym and back on the job."
Moving carefully, sending more glass crashing down as our weight bent the frame out of place and the panes slipped free, we crept back' to the safety of the parapet.
"Get on the radio," I told Diyan as he climbed up next to me. "Tell your troops to pull back their attack if they haven't broken in but to keep up the firing."
"They have been repulsed on all sides."
"Then tell them to cut their losses. We'll do the blitz from the inside."
We moved out. Angelina and I on the point where we could blast any resistance that appeared, while the others protected our flanks and rear. Forward at a sweaty trot. We had to move fast, sow discord as we went—and find He. The first door opened onto a great circular staircase that seemed to spiral down to infinity, I didn't like the looks of it, so I rolled some concussion grenades down it, and we pressed on across the roof.
"Where to?" Angelina asked.
"That tangle of turrets and buildings up ahead seems to be larger and more functional than most of this place. As good a guess as any." Something exploded on the tiles nearby, and Angelina picked the sniper out of a window above with a single snap shot from the waist. We ran a bit faster, then pressed against the wall above a straight drop to the valley below while I blew out a locked door. Then we were in.
The place had been designed by a madman. I know that is literally true, but you didn't have to know He to get the message. Corridors and stairs, twisted chambers, angled walls, even one spot where we had to crawl on our hands and knees under the low ceiling. This was where we had our first casualty. Five of us were clear of this room before the ceiling silently and swiftly descended and crushed the rear guard before he could even make a sound. We all were sweating harder. The enemy we met were not armed for the most part and either fled or were dropped by our needle guns. It was speed and silence now, and we moved as fast as we could between the bizarrely decorated walls, finding it easy to avoid looking at the incredible paintings that seemed to cover every square meter of available space.
"Just one moment," Angelina panted, pulling me to a stop as we came through a high archway to a staircase that spiraled out of sight below, each stone step being a different height from the others. "Do you know where we are going?"
"Not exactly," I panted in return. "Just penetrating the establishment to get ahead, of the fighting, while spreading a bit of confusion."
"I thought we had bigger ambitions. Like finding He."
"Any suggestions how we might go about that?" I am forced to admit that I snapped a bit as I said that. Angelina responded with saccharine sweetness.
"Why, yes. You might try turning on the time energy detector you have slung around your neck. I believe that is the reason we brought it."
"Just what I was going to do anyway," I said, lying to conceal the fact that I had forgotten completely about it in the white heat of the rampaging attack.
The needle swung about and pointed with exact precision to the floor beneath our feet.
"Down and down we go," I ordered. "Where the time-helix coils there will be found the He whom I am about to make into mincemeat." I meant it too since this was the third and last try. I had constructed a special bomb on which I had painted his name. It was a hellish mixture of a curdler—guaranteed to coagulate all protein within five meters—an explosive charge, a load of poisoned shrapnel, and a thermite bomb theoretically to cook the curdled, coagulated, poisoned body of He.
After this the fighting picked up. Some sort of flame-thrower below sent a wave of roiling smoke and fire up the stairs toward us that we could not pass. Singed and smoking, we went out through a hole I blasted in the wall and dropped into a laboratory of sorts. Row after row of bubbling retorts stretched away in all directions, hooked to a maze of crystal plumbing. Dark liquids dripped, and valves hissed foul-smelling steam. The workers here weren't armed, and they dropped before us. We were trotting slower now and gasping for breath.
"Ugh!" Angelina said, making a twisted face. "Have you seen just what is in those jars?"
"No, and I don't want to. Press on." Anything that could bother the ice-cool Angelina was something I had no desire to see at all. I was glad when we left this area behind and found another stairwell.
We were getting close. Resistance kept firming up, and we had to battle most of the way now. Only the fact that the defenders were haphazardly armed allowed us to get through at all. Apparently most of the weapons were at use on the walls because these people came at us with knives, axes, lengths of metal, anything and everything. Including their bare hands if that was all they had. Screaming and frothing, they rushed to the attack and slowed us just by the weight of their numbers. We had our next casualty when a man with a metal spike dropped from some cranny above and stabbed one of the Martians before I could shoot him. They died together, and all we could do was leave them and push on. I took a quick look at my watch and broke into a tired trot again. We were running out of time.
"Wait!" Diyan called out hoarsely. "The needle, it no longer points."
I waved everyone to a stop in a wide passage we were traversing, and they dropped, covering the flanks. I looked at the time energy detector that Diyan had been carrying.
"Which way was it pointing when you looked at it last?"
"Straight ahead, down the corridor. And there was no angle to the needle at all, as though this machine it points to were on this level."
"It only works when the time-helix is operating. It must be off now."
"Could He have gone?" Angelina asked, speaking aloud the words I was trying to keep out of my thoughts.
"Probably not," I said with mock sincerity. "In any case we have to push on as long as we can. One last effort now, dead ahead."
We pushed. And had another casualty when we attempted to cross a layer of writhing branches that were covered with thorns. Tipped with poison. I finally had to burn the stuff with our last thermite grenade. Ammunition and grenades were running very short. There was a brisk firefight at the next corridor junction that emptied my needle gun. I tossed it aside and kicked the heavy door that barred any more progress in this direction. It would have to be blown open, and my grenades were exhausted. I turned to Angelina just as a communication plate next to the door lit up.
"You have lost, the final time," He said, grinning wickedly at me from the screen.
"I'm always willing to talk," I said, then spoke to Angelina in a language I was sure He did not speak. "Any concussion grenades left?"
"I am talking, you will listen," He said.
"One," Angelina told me.
"I'm all ears," I said to him. "Take that door out," I said to her.
"I have dispatched all the people I need to a safe place in the past where we will never be found. I have sent the machines we will need, I have sent everything that will be needed to build a time-helix as well. I am the last to go, and when I leave, the time machinery will be destroyed behind me."
The grenade exploded, but the door was thick and remained stuck in the frame. Angelina sprayed it with explosive bullets. He talked on as though this weren't happening.
"I know who you are, little man from the future, and I know where you come from. Therefore I shall destroy you before you have a chance to be born. I will destroy you, my only enemy; then the past and the future and all eternity will be mine, mine, mine!"
He was screaming and slavering before he finished, and the door went down, and I was the first one through.
My bullets were exploding in the delicate machinery of the time-helix as my He-bomb arced through the air.
But he had already actuated the time-helix. Its green glow was gone; He was gone, the machinery left behind no longer needed. My hell-bomb exploded in empty air and was more of a danger to us than to the vanished one it had been intended for. We dropped to the floor as death whizzed overhead, and when we looked next, the machinery was dissolving and smoking.
He spoke again, and the muzzle of my gun locked for him.
"I made this recording in case I had to leave abruptly, so sorry." He chuckled insanely at his own bad humor. "I have gone now; you cannot follow me, but I can follow you through time. And destroy you. But you have other enemies with you, and I wish them to feel my vengeance, too. They will die, you will all die, everything will die; I control worlds, eternity, destroy worlds. I will destroy this Earth. I leave you only enough time to consider and suffer. You cannot escape.
"In one hour every nuclear weapon on this planet will be triggered.
"Earth will be destroyed."
