Blade closed his eyes again. Somewhere a cuckoo sang a last sad parting note. Wait until J heard about this! The plumbing was leaking. It had, of course, been a hasty setup.

Zoe leaned to kiss him softly on the mouth. Her lips were warm again. "Dick. Sweetheart. If you are some sort of secret agent, doing some sort of dreadfully mysterious and dangerous work, why don't you just simply tell me? Just one word. I'll understand and never ask another question."

Hah!

"I can't tell you," he said. "I can't tell you anything at all."

"Not even yes or no?"

"Not anything."

There was silence. The cuckoo cried a last time. Zoe was leaning over him, her marvelous taut breasts touching his face.

"All right," Zoe said at last. "Will you marry me, then? Right away. I love you so much that I'll settle for just that. Marry me and I'll try my best not to be a hindrance to you in whatever it is you do."

"I can't marry you."

When the computer thing began they voided his old Official Secrets Act and had made him sign a new one - with a special codicil. No marriage. J was the best security man in all Europe and he did not trust bedsprings, even connubial ones.

Zoe drew away from him. "You can't marry me? Or won't marry me?"

"Can't. I..."

They heard the phone ringing in the cottage then, a hundred yards back from the cliff, shrill and angry in the quietness.

Zoe stood up abruptly and starting brushing off her skirt. "I'm not expecting a call."

"I am. Come on. I'll carry you." Blade snatched her up and ran down the path, carrying her as effortlessly as a man carries a kitten. There was a four-step stile just at the turnoff to the cottage and he took it in stride, vaulting the high stone like a thoroughbred at the National.

Zoe cried out. "You fool. You'll cripple both of us!" Ordinarily she would have loved it. There was no particular hurry. Blade knew the phone would keep ringing. It did.

The phone was in the bedroom. Blade flung Zoe on the bed in a flurry of skirts and long bare legs and went to answer it. It was an ordinary black phone with no scrambler attachment. "Hello."

"Hello, dear boy. How are things?" J's tone was bland and calm as the Channel a hundred yards away. He sounded as if he were about to invite Blade to tea the next day.

"Things might be a little better," Blade said. He glanced at Zoe on the bed. She had arranged her skirt and was regarding him with an odd little smile, her chin cupped in her hand. A reclining Mona Lisa.

"My dear fellow," said J, "I hope I haven't interrupted anything." J sounded as though he actually meant it.

"Only a blazing quarrel, sir. Nothing to worry about. What is it? Is the deal going through?"

"It is," said J. "First thing in the morning. Can you be at your office in Whitehall to sign the necessary papers? Quite early?"

"Right, sir. I'll be there." He hung up. Blade went to a closet to get his light suitcase, very conscious of Zoe's dark eyes on him.

"Off again, darling?"

He nodded, still without looking at her, and began to toss things into the suitcase. He hadn't brought much down from London this time.

"When shall I see you again?"

At last he could be honest. "I don't know. And I'm not being evasive, Zoe. I just have no way of knowing when I will see you again."

He was about to add - perhaps not ever, but cut it off in time. That would be cruel. She loved him. She was going to imagine things anyway, but at least they would be in the realm of ordinary human fears. Bad enough. Tell her he was going into a new dimension, with only a fifty-fifty chance of ever getting back, and she would go mad. Or think he was. And anyway there was the ACT.

Blade said: "I have to do a little job. I can't say when it will be finished."

"Dick!"

He turned and she was holding out her arms to him, her eyes moist and her mouth trembling. He went to her. It was like one of those beautifully done scenes in the silent movies when no word is spoken and no shred of meaning lost.

She pulled him down on top of her. He took her tenderly, then with a rising lust and ardent savagery, matched by her own, until the peak was reached and they could be tender again.

Blade did not tarry. He left her crumpled and pale and completed, weeping a little, and went away.

He entered London with the dawn. He drove straight to the Tower - J had meant him to read Tower for Whitehall - and found J waiting for him by the site of the old Water Gate. J was wearing a Burberry against the morning chill and smoking his pipe. The harsh morning light made him look older then sixty, and the sacs under his eyes were a flaccid purple.

Two burly Special Branch types were waiting for them near a postern. As they headed for it Blade looked at the head of M16A and asked, "There is no possible way out of the Official Secrets Act, sir? Ever?"

J's eyes were compassionate above their fleshy bags. In a tired voice he said, "But of course there is, my dear boy. Death."

The Special Branch men took them down a long ramp and into a tunnel that emerged in a maze of subbasements and, finally, to the bronze elevator door that Blade remembered so well. Even J was not permitted beyond this point when an X-Dimension experiment was GO.

They shook hands briefly. J looked as weary, and worried, as Blade had ever seen him. He had little to say.

"Good luck, my boy. Seems strange to say this - where you're going - but don't worry about things here. You've signed all the proper papers and your affairs are in order. I'll take care of everything in the event..."

They were standing a little aside from the armed guards, waiting for the elevator to come up. Blade smiled at his boss and half whispered, "I've been thinking about that, sir. In the event - I'll just be a non-person, won't I? That should cause a sweat over at Somerset House."

It was an effort, more than anything, to cheer the old chap up a bit. Blade had never seen him looking so miserable.

J took him seriously. "It will be arranged, my boy. It will be taken care of. Here's your lift. Good-bye."

Ten minutes later Richard Blade, wearing only the usual loincloth, followed Lord Leighton into the master computer room. The hunchbacked old scientist, in a soiled white smock, hobbled on polio-ruined legs through a maze of lesser computers. Blade, with a feeling of some revulsion, listened to the song of the future: One-oh - one - oh - one-oh-one-oh - . Binary logic. Be-bop-be-bop-be-bop-be-bop - . Milliseconds that would soon be nanoseconds. One billionth of a second. Spinning magnetic drums and tiny bulbs flashing GO-GO-GO-GO.

It was most certainly GO. They entered the small room where the dimensional computer waited like a gray crackled Moloch. Blade had not been in this room since his first trip through the computer. It had not changed. There were the thousands of multicolored wires running through portholes into the penetrailia of the vast machine. There was the small square of floor covered with rubberized fabric. There was the glass booth and the chair that always reminded Blade of an electric chair.

And yet everything had changed. Lord L, as he applied tar-smelling ointment to Blade's huge body, waved a fragile hand at the monster.

"Completely rebuilt. Radical changes. The old one was only sixth generation - this one is at least eight. Skipped one, you see."

Blade, who knew that conventional computers were only in the third generation, was impressed. This crippled old genius was already five generations ahead of the rest of the world in cybernetics. That in itself, with all its implications, should get England back in the race. Was this trip really necessary?

He was in the chair now and the old man was carefully taping the shiny electrodes to Blade's flesh. They were the size of a shilling and shaped like a cobra's head.

Lord Leighton finished the job and flashed his tawny eyes at Blade. "You're nervous. Much more so than the first time out. Afraid?"

Blade was not a liar. "Yes, sir. A bit. The first trip was an error. It happened so fast I had no time to anticipate. I hadn't had time to tense up and I didn't know where I was going."

Lord Leighton patted his shoulder and said, with perfect logic, "You don't know where you're going this time, either. Do you now? But don't let it worry you, my boy. I have made the most complex calculations and the matter is now quite proved out. I'll have you back all in good time. In the meantime you must remember - make no conscious effort to remember! The memory molecule will take care of all that. Ready?"

"As ever I'll be," said Blade grimly. "Get on with it, then."

Lord Leighton closed a switch.

The first time there had been pain. Great slashing scarlet pain. This time there was no pain, only a huge and relentless hand pressing him beneath tons of water. He could not breathe and it did not matter. He did not need to breathe. He was hurtling through a vacuum filled with thunder. Silent thunder that he felt but could not hear.

Richard Blade began to disintegrate. He watched the process with a cold part of his brain that did not care. He felt nothing. He was not interested. He was bored with it all. He saw his hands fall off and his feet detach. His head left his body, which by now was impaled on an icicle the size of the Empire State building. His head circled the body, which was still coming apart, like the planes after King Kong. His belly had split now and his viscera were coming out like pink and blue ribbons and getting tangled in the buzzing planes.

He saw the fist coming. A fist the size of the world. Blade's floating head could not duck. It could only wait He smiled. What did it matter? It was only a fist. The size of the world.

The fist slammed into him and at last there was pain.
