"Quiet. They'll hear us. Oh, G.o.d, they'll find us soon enough-"

Below them, Mink's voice. The husband stopped. There was a great universal humming and sizzling, a screaming and giggling. Downstairs the audio-televisor buzzed and buzzed insistently, alarmingly, violently. Is that Helen calling? thought Mrs. Morris. And is she calling about what I think she's calling about?

Footsteps came into the house. Heavy footsteps.

"Who's coming in my house?" demanded Henry angrily. "Who's tramping around down there?"

Heavy feet. Twenty, thirty, forty, fifty of them. Fifty persons crowding into the house. The humming. The giggling of the children. "This way!" cried Mink, below.

"Who's downstairs?" roared Henry. "Who's there!"

"Hush. Oh, nononononono!" said his wife weakly, holding him. "Please, be quiet. They might go away."

"Mom?" called Mink. "Dad?" A pause. "Where are you?"

Heavy footsteps, heavy, heavy, very heavy footsteps, came up the stairs. Mink leading them.

"Mom?" A hesitation. "Dad?" A waiting, a silence.

Humming. Footsteps toward the attic. Mink's first.

They trembled together in silence in the attic, Mr. and Mrs. Morris. For some reason the electric humming, the queer cold light suddenly visible under the door crack, the strange odor and the alien sound of eagerness in Mink's voice finally got through to Henry Morris too. He stood, shivering, in the dark silence, his wife beside him.

"Mom! Dad!"

Footsteps. A little humming sound. The attic lock melted. The door opened. Mink peered inside, tall blue shadows behind her.

"Peekaboo," said Mink.

THE TOYNBEE CONVECTOR.

"GOOD! GREAT! BRAVO FOR ME!"

Roger Shumway flung himself into the seat, buckled himself in, revved the rotor and drifted his Dragonfly Super-6 helicopter up to blow away on the summer sky, heading south toward La Jolla.

"How lucky can you get?"

For he was on his way to an incredible meeting.

The time traveler, after a hundred years of silence, had agreed to be interviewed. He was, on this day, 130 years old. And this afternoon, at four o'clock sharp, Pacific time, was the anniversary of his one and only journey in time.

Lord, yes! One hundred years ago, Craig Bennett Stiles had waved, stepped into his Immense Clock, as he called it, and vanished from the present. He was and remained the only man in history to travel in time. And Shumway was the one and only reporter, after all these years, to be invited in for afternoon tea. And? The possible announcement of a second and final trip through time. The traveler had hinted at such a trip.

"Old man," said Shumway, "Mr. Craig Bennett Stiles-here I come!"

The Dragonfly, obedient to fevers, seized a wind and rode it down the coast.

The old man was there waiting for him on the roof of the Time Lamasery at the rim of the hang gliders' cliff in La Jolla. The air swarmed with crimson, blue and lemon kites from which young men shouted, while young women called to them from the land's edge.

Stiles, for all his 130 years, was not old. His face, blinking up at the helicopter, was the bright face of one of those hang-gliding Apollo fools who veered off as the helicopter sank down.

Shumway hovered his craft for a long moment, savoring the delay.

Below him was a face that had dreamed architectures, known incredible loves, blueprinted mysteries of seconds, hours, days, then dived in to swim upstream through the centuries. A sunburst face, celebrating its own birthday.

For on a single night, one hundred years ago, Craig Bennett Stiles, freshly returned from time, had reported by Telstar around the world to billions of viewers and told them their future.

"We made it!" he said. "We did it! The future is ours. We rebuilt the cities, freshened the small towns, cleaned the lakes and rivers, washed the air, saved the dolphins, increased the whales, stopped the wars, tossed solar stations across s.p.a.ce to light the world, colonized the moon, moved on to Mars, then Alpha Centauri. We cured cancer and stopped death. We did it-Oh Lord, much thanks-we did it. Oh, future's bright and beauteous spires, arise!"

He showed them pictures, he brought them samples, he gave them tapes and LP records, film and sound ca.s.settes of his wondrous roundabout flight. The world went mad with joy. It ran to meet and make that future, fling up the cities of promise, save all and share with the beasts of land and sea.

The old man's welcoming shout came up the wind. Shumway shouted back and let the Dragonfly simmer down in its own summer weather.

Craig Bennett Stiles, 130 years old, strode forward briskly and, incredibly, helped the young reporter out of his craft, for Shumway was suddenly stunned and weak at this encounter.

"I can't believe I'm here," said Shumway.

"You are, and none too soon," laughed the time traveler. "Any day now, I may just fall apart and blow away. Lunch is waiting. Hike!"

A parade of one, Stiles marched off under the fluttering rotor shadows that made him seem a flickering newsreel of a future that had somehow pa.s.sed.

Shumway, like a small dog after a great army, followed.

"What do you want to know?" asked the old man as they crossed the roof, double time.

"First," gasped Shumway, keeping up, "why have you broken silence after a hundred years? Second, why to me? Third, what's the big announcement you're going to make this afternoon at four o'clock, the very hour when your younger self is due to arrive from the past-when, for a brief moment, you will appear in two places, the paradox: the person you were, the man you are, fused in one glorious hour for us to celebrate?"

The old man laughed. "How you do go on!"

"Sorry." Shumway blushed. "I wrote that last night. Well. Those are the questions."

"You shall have your answers." The old man shook his elbow gently. "All in good-time."

"You must excuse my excitement," said Shumway. "After all, you are a mystery. You were famous, world-acclaimed. You went, saw the future, came back, told us, then went into seclusion. Oh, sure; for a few weeks, you traveled the world in ticker-tape parades, showed yourself on TV, wrote one book, gifted us with one magnificent two-hour television film, then shut yourself away here. Yes, the time machine is on exhibit below, and crowds are allowed in each day at noon to see and touch. But you yourself have refused fame-"

"Not so." The old man led him along the roof. Below in the gardens, other helicopters were arriving now, bringing TV equipment from around the world to photograph the miracle in the sky, that moment when the time machine from the past would appear, shimmer, then wander off to visit other cities before it vanished into the past. "I have been busy, as an architect, helping build that very future I saw when, as a young man, I arrived in our golden tomorrow!"

They stood for a moment watching the preparations below. Vast tables were being set up for food and drink. Dignitaries would be arriving soon from every country of the world to thank-for a final time, perhaps-this fabled, this almost mythic traveler of the years.

"Come along," said the old man. "Would you like to come sit in the time machine? No one else ever has, you know. Would you like to be the first?"

No answer was necessary. The old man could see that the young man's eyes were bright and wet.

"There, there," said the old man. "Oh, dear me; there, there."

A gla.s.s elevator sank and took them below and let them out in a pure white bas.e.m.e.nt at the center of which stood- The incredible device.

"There." Stiles touched a b.u.t.ton and the plastic sh.e.l.l that had for one hundred years encased the time machine slid aside. The old man nodded. "Go. Sit."

Shumway moved slowly toward the machine.

Stiles touched another b.u.t.ton and the machine lit up like a cavern of spider webs. It breathed in years and whispered forth remembrance. Ghosts were in its crystal veins. A great G.o.d spider had woven its tapestries in a single night. It was haunted and it was alive. Unseen tides came and went in its machinery. Suns burned and moons hid their seasons in it. Here, an autumn blew away in tatters; there, winters arrived in snows that drifted in spring blossoms to fall on summer fields.

The young man sat in the center of it all, unable to speak, gripping the armrests of the padded chair.

"Don't be afraid," said the old man gently. "I won't send you on a journey."

"I wouldn't mind," said Shumway.

The old man studied his face. "No, I can see you wouldn't. You look like me one hundred years ago this day. d.a.m.n if you aren't my honorary son."

The young man shut his eyes at this, and the lids glistened as the ghosts in the machine sighed all about him and promised him tomorrows.

"Well, what do you think of my Toynbee Convector?" said the old man briskly, to break the spell.

He cut the power. The young man opened his eyes.

"The Toynbee Convector? What-"

"More mysteries, eh? The great Toynbee, that fine historian who said any group, any race, any world that did not run to seize the future and shape it was doomed to dust away in the grave, in the past."

"Did he say that?"

"Or some such. He did. So, what better name for my machine, eh? Toynbee, wherever you are, here's your future-seizing device!"

He grabbed the young man's elbow and steered him out of the machine.

"Enough of that. It's late. Almost time for the great arrival, eh? And the earth-shaking final announcement of that old time traveler Stiles! Jump!"

Back on the roof, they looked down on the gardens, which were now swarming with the famous and the near famous from across the world. The nearby roads were jammed; the skies were full of helicopters and hovering biplanes. The hang gliders had long since given up and now stood along the cliff rim like a mob of bright pterodactyls, wings folded, heads up, staring at the clouds, waiting.

"All this," the old man murmured, "my G.o.d, for me."

The young man checked his watch.

"Ten minutes to four and counting. Almost time for the great arrival. Sorry; that's what I called it when I wrote you up a week ago for the News. That moment of arrival and departure, in the blink of an eye, when, by stepping across time, you changed the whole future of the world from night to day, dark to light. I've often wondered-"

"What?"

Shumway studied the sky. "When you went ahead in time, did no one see you arrive? Did anyone at all happen to look up, do you know, and see your device hover in the middle of the air, here and over Chicago a bit later, and then New York and Paris? No one?"

"Well," said the inventor of the Toynbee Convector, "I don't suppose anyone was expecting me! And if people saw, they surely did not know what in blazes they were looking at. I was careful, anyway, not to linger too long. I needed only time to photograph the rebuilt cities, the clean seas and rivers, the fresh, smog-free air, the unfortified nations, the saved and beloved whales. I moved quickly, photographed swiftly and ran back down the years home. Today, paradoxically, is different. Millions upon millions of mobs of eyes will be looking up with great expectations. They will glance, will they not, from the young fool burning in the sky to the old fool here, still glad for his triumph?"

"They will," said Shumway. "Oh, indeed, they will!"

A cork popped. Shumway turned from surveying the crowds on the nearby fields and the crowds of circling objects in the sky to see that Stiles had just opened a bottle of champagne.

"Our own private toast and our own private celebration."

They held their gla.s.ses up, waiting for the precise and proper moment to drink.

"Five minutes to four and counting. Why," said the young reporter, "did no one else ever travel in time?"

"I put a stop to it myself," said the old man, leaning over the roof, looking down at the crowds. "I realized how dangerous it was. I was reliable, of course, no danger. But, Lord, think of it-just anyone rolling about the bowling-alley time corridors ahead, knocking tenpins headlong, frightening natives, shocking citizens somewhere else, fiddling with Napoleon's life line behind or restoring Hitler's cousins ahead? No, no. And the government, of course, agreed-no, insisted-that we put the Toynbee Convector under sealed lock and key. Today, you were the first and last to fingerprint its machinery. The guard has been heavy and constant, for tens of thousands of days, to prevent the machine's being stolen. What time do you have?"

Shumway glanced at his watch and took in his breath.

"One minute and counting down-"

He counted, the old man counted. They raised their champagne gla.s.ses.

"Nine, eight, seven-"

The crowds below were immensely silent. The sky whispered with expectation. The TV cameras swung up to scan and search.

"Six, five-"

They clinked their gla.s.ses.

"Four, three, two-"

They drank.

"One!"

They drank their champagne with a laugh. They looked to the sky. The golden air above the La Jolla coastline waited. The moment for the great arrival was here.

"Now!" cried the young reporter, like a magician giving orders.

"Now," said Stiles, gravely quiet.

Nothing.

Five seconds pa.s.sed.

The sky stood empty.

Ten seconds pa.s.sed.

The heavens waited.
