How long? In the sump in the next room, the bomb lay quietly ticking. How long…?

The main assembly was ready now. I laid out cables, tying my apparatus in to the atomic power-source buried under the vault. The demand, for one short instant, would tax even those mighty engines. I fixed hooks at the proper points in the room, wove soft aluminum wire in the correct pattern. I was almost finished now. How long? I made the last connections, cleared away the litter. The matter transmitter stood on the table, complete. At any instant, the bomb would reduce it-and the secret of its construction-to incandescent gas-unless I transmitted the bomb out of range first. I turned toward the laundry room-and the telephone rang. I hesitated, then crossed the room and snatched it up.

"Listen to me," Kayle said grimly. "Give me straight, fast answers. You said the Master Tape was there, in the vault with you. Now tell me: What does it look like?"

"What?"

"The… ah… dummy tape. What is its appearance?"

"It's a roughly square plastic container, bright yellow, about a foot thick. What about it?"

Kayle's voice sounded strained. "I've made inquiries. No one here seems to know the exact present location of the Master Tape. Each department says that they were under the impression that another handled the matter. I'm unable to learn who, precisely, removed the Tape from the vault. Now you say there is a yellow plastic container-"

"I know what the Master Tape looks like," I said. "This is either it or a hell of a good copy."

"Granthan," Kayle said. There was a note of desperation in his voice now. "There have been some blunders made. I knew you were under the influence of the Gool. It didn't occur to me that I might be too. Why did I make it possible for you to successfully penetrate to the Central Vault? There were a hundred simpler ways in which I could have dealt with the problem. We're in trouble, Granthan, serious trouble. The tape you have there is genuine. We've all played into the enemy's hands."

"You're wasting valuable time, Kayle," I snapped. "When does the bomb go up?"

"Granthan, there's little time left. Bring the Master Tape and leave the vault-"

"No dice, Kayle. I'm staying until I finish the transmitter, then-"

"Granthan! If there's anything to your mad idea of such a machine, destroy it! Quickly! Don't you see the Gool would only have given you the secret in order to enable you to steal the tape!"

I cut him off. In the sudden silence, I heard a distant sound-or had I sensed a thought? I strained outward…

"… volunteered… damn fool… thing on my head is heavy… better work…

"… now… okay… valve, gas… kills in a split second… then get out…"

I stabbed out, pushed through the obscuring veil of masonry, sensed a man in the computer room, dressed in gray coveralls, a grotesque shield over his head and shoulders. He reached for a red-painted valve I struck at his mind, felt him stagger back, fall. I fumbled in his brain, stimulated the sleep center. He sank deep into unconsciousness. I leaned against the table, weak with the reaction. Kayle had almost tricked me that time.

I reached out again, swept the area with desperate urgency. Far away, I sensed the hazy clutter of many minds, out of range. There was nothing more. The poisonous gas had been the only threat-except the bomb itself. But I had to move fast, before my time ran out, to transmit the bomb to a desert area…

I paused, stood frozen in mid-move. A desert. What desert?

The transmitter operated in accordance with as rigid a set of laws as did the planets swinging in their orbits; strange laws, but laws of nature none the less. No receiver was required. The destination of the mass under transmission was determined by the operator, holding in his mind the five-dimensional conceptualization of the target, guiding the action of the machine.

And I had no target.

I could no more direct the bomb to a desert without a five-fold grasp of its multi-ordinal spatial, temporal, and entropic coordinates than I could fire a rifle at a target in the dark.

I was like a man with a grenade in his hand, pin pulled-and locked in a cell.

I swept the exocosm again, desperately. And caught a thin, live line. I traced it; it cut through the mountain, dived deep underground, crossed the boundless plain…

Never branching, it bored on, turning upward now-and ending.

I rested, gathering strength, then probed, straining…

There was a room, men. I recognized Kayle, gray-faced, haggard. A tall man in braided blue stood near him. Others stood silently by, tension on every face. Maps covered the wall behind them.

I was looking into the War Room at the Pentagon in Washington. The line I had traced was the telephonic hotline, the top-security link between the Record Center and the command level. It was a heavy cable, well protected and always open. It would free me from the trap. With Gool-tutored skill I scanned the room, memorized its co-ordinates. Then I withdrew.

Like a swimmer coming up from a long dive, I fought my way back to the level of immediate awareness. I sagged into a chair, blinking at the drab walls, the complexity of the transmitter. I must move fast now, place the bomb in the transmitter's field, direct it at the target. With an effort I got to my feet, went to the sump, lifted the cover. I grasped the lifting eye, strained-and the bomb came up, out onto the floor. I dragged it to the transmitter…

And only then realized what I'd been about to do.

My target.

The War Room-the nerve-center of Earth's defenses. And I had been ready to dump the hell-bomb there. In my frenzy to be rid of it I would have played into the hands of the Gool.

I went to the phone.

"Kayle! I guess you've got a recorder on the line. I'll give you the details of the transmitter circuits. It's complicated, but fifteen minutes ought to-"

"No time," Kayle cut in. "I'm sorry about everything, Granthan. If you've finished the machine, it's a tragedy for humanity-if it works. I can only ask you to try-when the Gool command comes-not to give them what they want. I'll tell you, now, Granthan. The bomb blows in-" there was a pause-"two minutes and twenty-one seconds. Try to hold them off. If you can stand against them for that long at least-"

I slammed the phone down, cold sweat popping out across my face. Two minutes… too late for anything. The men in the War Room would never know how close I had come to beating the Gool-and them.

But I could still save the Master Tape. I wrestled the yellow plastic case that housed the tape onto the table, into the machine.

And the world vanished in a blaze of darkness, a clamor of silence.
