"You think that's the old obsession talking?" he asked. "Could be. But look at this plant, here. It generates every kilowatt of current used between Trenton and Albany, the New York metropolitan area included. Except for a few little storage-battery or Diesel generator systems, that couldn't handle one tenth of one per cent of the barest minimum load, it's been the only source of electric current here since 1962, when the last coal-burning power plant was dismantled. Knock this plant out and you darken every house and office and factory and street in the area. You immobilize the elevators—think what that would mean in lower and midtown Manhattan alone. And the subways. And the new endless-belt conveyors that handle eighty per cent of the city's freight traffic. And the railroads—there aren't a dozen steam or Diesel locomotives left in the whole area. And the pump stations for water and gas and fuel oil. And seventy per cent of the space-heating is electric, now. Why, you can't imagine what it'd be like. It's too gigantic. But what you can imagine would be a nightmare.

"You know, it wasn't so long ago, when every home lighted and heated itself, and every little industry was a self-contained unit, that a fool couldn't do great damage unless he inherited a throne or was placed in command of an army, and that didn't happen nearly as often as our leftist social historians would like us to think. But today, everything we depend upon is centralized, and vulnerable to blunder-damage. Even our food—remember that poisoned soft-drink horror in Chicago, in 1963; three thousand hospitalized and six hundred dead because of one man's stupid mistake at a bottling plant." He shook himself slightly, as though to throw off some shadow that had fallen over him, and looked at his watch. "Sixteen hundred. How did you get here? Fly your own plane?"

"No; I came by T.W.A. from Pittsburgh. I have a room at the new Midtown City hotel, on Forty-seventh Street: I had my luggage sent on there from the airport and came out on the Long Island subway."

"Fine. I have a room at Midtown City, myself, though I sleep here about half the time." He nodded toward a door on the left. "Suppose we go in and have dinner together. This cafeteria, here, is a horrible place. It's run by a dietitian instead of a chef, and everything's so white-enamel antiseptic that I swear I smell belladonna-icthyol ointment every time I go in the place. Wait here till I change clothes."

At the Long Island plant, no one was concerned about espionage—neither the processes nor the equipment used there were secret—but the countersabotage security was fantastically thorough. Every person or scrap of material entering the reactor area was searched; the life-history of every man and woman employed there was known back to the cradle. A broad highway encircled it outside the fence, patrolled night and day by twenty General Stuart cavalry-tanks. There were a thousand soldiers, and three hundred Atomic Power Authority police, and only God knew how many F.B.I, and Central Intelligence undercover agents. Every supervisor and inspector and salaried technician was an armed United States deputy marshal. And nobody, outside the Department of Defense, knew how much radar and counter-rocket and fighter protection the place had, but the air-defense zone extended from Boston to Philadelphia and as far inland as Wilkes-Barre, Pennsylvania.

The Long Island Nuclear Power Plant, Melroy thought, had all the invulnerability of Achilles—and no more.

The six new Doernberg-Giardano breeder-reactors clustered in a circle inside a windowless concrete building at the center of the plant. Beside their primary purpose of plutonium production, they furnished heat for the sea-water distillation and chemical extraction system, processing the water that was run through the steam boilers at the main power reactors, condensed, redistilled, and finally pumped, pure, into the water mains of New York. Safe outside the shielding, in a corner of a high-ceilinged room, was the plyboard-screened on-the-job office of the Melroy Engineering Corporation's timekeepers and foremen. Beyond, along the far wall, were the washroom and locker room and lunch room of the workmen.

Sixty or seventy men, mostly in white coveralls and all wearing identification badges and carrying dosimeters in their breast pockets and midget Geigers strapped to their wrists, were crowded about the bulletin-board in front of the makeshift office. There was a hum of voices—some perplexed or angry, but mostly good-humored and bantering. As Melroy and Doris Rives approached, the talking died out and the men turned. In the sudden silence, one voice, harshly strident, continued:

"... do they think this is, anyhow? We don't hafta take none of that."

Somebody must have nudged the speaker, trying without success to hush him. The bellicose voice continued, and Melroy spotted the speaker—short, thick-set, his arms jutting out at an angle from his body, his heavy features soured with anger.

"Like we was a lotta halfwits, 'r nuts, 'r some'n! Well, we don't hafta stand for this. They ain't got no right—"

Doris Rives clung tighter to Melroy's arm as he pushed a way for himself and her through the crowd and into the temporary office. Inside, they were met by a young man with a deputy marshal's badge on his flannel shirt and a .38 revolver on his hip.

"Ben Puryear: Dr. Rives," Melroy introduced. "Who's the mouthy character outside?"

"One of the roustabouts; name's Burris," Puryear replied. "Wash-room lawyer."

Melroy nodded. "You always get one or two like that. How're the rest taking it?"

Puryear shrugged. "About how you'd expect. A lot of kidding about who's got any intelligence to test. Burris seems to be the only one who's trying to make an issue out of it."

"Well, what are they doing ganged up here?" Melroy wanted to know. "It's past oh-eight-hundred; why aren't they at work?"

"Reactor's still too hot. Temperature and radioactivity both too high; radioactivity's still up around eight hundred REM's."

"Well, then, we'll give them all the written portion of the test together, and start the personal interviews and oral tests as soon as they're through." He turned to Doris Rives. "Can you give all of them the written test together?" he asked. "And can Ben help you—distributing forms, timing the test, seeing that there's no fudging, and collecting the forms when they're done?"

"Oh, yes; all they'll have to do is follow the printed instructions." She looked around. "I'll need a desk, and an extra chair for the interview subject."

"Right over here, doctor." Puryear said. "And here are the forms and cards, and the sound-recorder, and blank sound disks."

"Yes," Melroy added. "Be sure you get a recording of every interview and oral test; we may need them for evidence."

He broke off as a man in white coveralls came pushing into the office. He was a scrawny little fellow with a wide, loose-lipped mouth and a protuberant Adam's apple; beside his identity badge, he wore a two-inch celluloid button lettered: I.F.A.W. STEWARD.

"Wanta use the phone," he said. "Union business."

Melroy gestured toward a telephone on the desk beside him. The newcomer shook his head, twisting his mouth into a smirk.

"Not that one; the one with the whisper mouthpiece," he said. "This is private union business."

Melroy shrugged and indicated another phone. The man with the union steward's badge picked it up, dialed, and held a lengthy conversation into it, turning his head away in case Melroy might happen to be a lip reader. Finally he turned.

"Mr. Crandall wants to talk to you," he said, grinning triumphantly, the phone extended to Melroy.
