It was the darnedest traffic jam I’d ever seen in White Plains. For two blocks ahead of me, Main Street was gutter to gutter with stalled cars, trucks and buses.

If I hadn’t been in such a hurry to get back to the shop, I might have paid more attention. I might have noticed nobody was leaning on his horn. Or that at least a quarter of the drivers were out peering under their hoods.

But at the time it didn’t register. I gave the tie-up a passing glance and was turning up the side street toward Biltom Electronics--Bill-Tom, get it?--when I saw Marge threading her way to the curb. She was leading a small blonde girl of about eight, who clutched a child-size hatbox in her hand. Marge was hot and exasperated, but small fry was as cool and composed as a vanilla cone.

I waited. Even flushed and disheveled, Marge is a treat to look at. She is tall and slender, with brown eyes that match her hair, a smile that first crinkles around her eyes, then sneaks down and becomes a full-fledged grin--

But I’m getting off the subject.

“Honestly, Bill!” Marge said as she saw me. “The traffic nowadays! We’ve been tied up for fifteen minutes. I finally decided to get off the bus and walk, even though it is about a hundred in the shade.”

“Come along to the shop,” I suggested. “The reception room is air-conditioned and you can watch the world’s first baseball game telecast in color. The Giants versus the Dodgers, Carl Erskine pitching.”

Marge brightened. “That’ll be more fun than shopping, won’t it, Doreen?” she asked, looking down at the kid. “Bill, this is Doreen. She lives across the street from me. Her mother’s at the dentist and I said I’d look after her for the day.”

“Hello, Doreen,” I said. “What have you in the hatbox? Doll clothes?”

Doreen gave me a look of faint disgust. “No,” she piped, in a high treble. “An unhappy genii.”

“An unhappy--” I did a double take. “Oh, an unhappy genii? Maybe he’s unhappy because you won’t let him out, ha ha.” Even to myself, I sounded idiotic.

Doreen looked at me pityingly. “It’s not a he, it’s a thing. Elmer made it.”

I knew when I was losing, so I quit.

I hurried Marge and Doreen along toward our little two-story building. Once we got into the air-conditioned reception room, Marge sank down gratefully onto the settee and I switched on the television set with the big 24-inch tube Tom had built.

Biltom Electronics makes TV components, computer parts, things like that. Tom Kennedy is the brains. Me, Bill Rawlins, I do the legwork, and tend to the business details.

“It’s uncanny the way all those cars suddenly stopped when our bus broke down,” Marge said as we waited for the picture to come on. “Any day now this civilization of ours will get so complicated a bus breaking down someplace will bring the whole thing to a halt. Then where will we be?”

“Elmer says silly-zation is doomed!” Doreen put in happily.

The way she rolled the word out made me stare at her.

Marge only nodded. “That’s what Elmer says, all right,” she agreed, a trifle grim.

“Why does Elmer say silly-zation is doomed?” I asked Doreen.

“Because it’s getting hotter.” The kid gave it to me straight. “All the ice at the North Pole is gonna melt. The ocean is gonna rise two hundred feet. Then everybody who doesn’t live on a hill is gonna be drownded. That’s what Elmer says and Elmer isn’t ever wrong.”

Doreen they called her! Why not Cassandra? The stuff kids spout these days!

I gave her a foolish grin. I wanted Marge to get the idea I was really a family man at heart. “That’s very interesting, Doreen. Now look, there’s the baseball game. Let’s watch, shall we?”

We weren’t very late after all. It was the top half of the second inning, the score one to one, Erskine in trouble with two men on and only one down. The colors were beautiful. Marge and I were just settling back to watch when Doreen wrinkled her nose.

“I saw that game yesterday!” she announced.

“You couldn’t have, sweetheart,” I told her. “Because it’s only being played today. The world’s first ball game ever broadcast in color.”

“There was a game on Elmer’s TV,” Doreen insisted. “The picture was bigger and the colors prettier, too.”

“Absolutely impossible.” I was a little sore. I hate kids who tell fibs. “There never was a game broadcast in color before. And, anyway, you won’t find a color tube this big any place outside of a laboratory.”

“But it’s true, Bill.” Marge looked at me, wide-eyed. “Elmer only has a little seven-inch black and white set his uncle gave him. But he’s rigged up some kind of lens in front of it, and it projects a big color picture on a white screen.”

I saw that she was serious. My eyes bugged slightly. “Listen,” I said, “who is this Elmer character? I want to meet him!”

“He’s my cousin from South America,” Doreen answered. “He thinks grownups are stupid.” She turned to Marge. “I have to go to the bathroom,” she said primly.

“Through that door.” Marge pointed.

Doreen trotted out, clutching her hat box.

“Elmer thinks grownups are stupid?” I howled. “Listen, how old is this character who says silly-zation is doomed and can convert a black and white broadcast into color?”

“He’s thirteen,” Marge told me. I goggled at her. “Thirteen,” she repeated. “His father is some South American scientist. His mother died ten years ago.”

I sat down beside her. I lit a cigarette. My hands were shaking. “Tell me about him. All about him.”

“Why, I don’t know very much,” Marge said. “Last year Elmer was sick, some tropic disease. His father sent him up here to recuperate. Now Alice--that’s his aunt, Doreen’s mother--is at her wits’ end, he makes her so nervous.”

I lit another cigarette before I realized I already had one. “And he invents things? A boy genius? Young Tom Edison and all that?”

Marge frowned. “I suppose you could say that,” she conceded. “He has the garage full of stuff he’s made or bought with the allowance his father sends him. And if you come within ten feet of it without permission, you get an electric shock right out of thin air. But that’s only part of it. It--” she gave a helpless gesture--”it’s Elmer’s effect on everybody. Everybody over fifteen, that is. He sits there, a little, dark, squinched-up kid wearing thick glasses and talking about how climatic changes inside fifty years will flood half the world, cause the collapse of civilization--”

“Wait a minute!” I cut in. “Scientists seem to think that’s possible in a few thousand years. Not fifty.”

“Elmer says fifty,” Marge stated flatly. “From the way he talks, I suspect he’s figured out a way to speed things up and is going to try it some day just to see if it works. Meanwhile he fools around out there in the garage, sneering about the billions of dollars spent to develop color TV. He says his lens will turn any ordinary broadcast into color for about twenty-five dollars. He says it’s typical of the muddled thinking of our so-called scientists--I’m quoting now--to do everything backward and overlook fundamental principles.”
