have helped, but it didn't. He and the other Jovian pioneers had hoped it wouldn't happen and, of course, it had.
"Ben Wrail," said a voice in the room.
Wrail swung around, away from the window.
"Manning!" he yelled, and the man in the center of the room grinned bleakly at him. "How did you come in without me hearing you? When did you get here?"
"I'm not here," said Greg. "I'm back on Earth."
"You're what?" asked Wrail blankly. "That's a pretty silly statement, isn't it, Manning? Or did you decide to loosen up and pull a gag now and then?"
"I mean it," said Manning. "This is just an image of me. My body is back on Earth."
"You mean you're dead? You're a ghost?"
The grin widened, but the face was bleak as ever.
"No, Ben, I'm just alive as you are. Let me explain. This is a television image of me. Three-dimensional television. I can travel anywhere like this."
Wrail sat down in the chair again. "I don't suppose there'd be any use trying to shake hands with you."
"No use," agreed Manning's image. "There isn't any hand."
"Nor asking you to have a chair?"
Manning shook his head.
"Anyhow," said Wrail, "I'm damn glad to see you—or think I see you. I don't know which. Figure you can stay and talk with me a while?"
"Certainly," said Manning. "That is what I came for. I want to ask your help."
"Listen," declared Wrail, "you can't be on Earth, Manning. I say something to you and you answer right back. That isn't possible. You can't hear anything I say until 45 minutes after I say it, and then I'd have to wait another 45 minutes to hear your answer."
"That's right," agreed the image, "if you insist upon talking about the velocity of light. We have something better than that."
"We?"
"Russell Page and myself. We have a two-way television apparatus that works almost instantaneously. To all purposes, so far as the distance between Earth and Callisto is concerned, it is instantaneous."
Wrail's jaw fell. "Well, I be damned. What have you two fellows been up to now?"
"A lot," said Manning laconically. "For one thing we are out to bust Interplanetary Power. Bust them wide open. Hear that, Wrail?"
Wrail stared in stupefaction. "Sure, I hear. But I can't believe it."
"All right then," said Manning grimly, "we'll give you proof. What could you do, Ben, if we told you what was happening on the stock market in New York ... without you having to wait the 45 minutes it takes the quotations to get here?"
Wrail sprang to his feet. "What could I do? Why, I could run the pants off every trader in the exchange! I could make a billion a minute!" He stopped and looked at the image. "But this isn't like you. This isn't the way you'd do things."
"I don't want you to hurt anyone but Chambers," said Manning. "If somebody else gets in the way, of course they have to take the rap along with him. But I do want to give Chambers a licking. That's what I came here to see you about."
"By Heaven, Greg, I'll do it," said Wrail. He stepped quickly forward, held out his hand to close the deal, and encountered only air.
Manning's image threw back its head and laughed.
"That's your proof, Ben. Good enough?"
"I'll say it is," said Wrail shakily, looking down at the solid-seeming hand that his own had gone right through.
November 6, 2153, was a day long remembered in financial circles throughout the Solar System. The Ranthoor market opened easy with little activity. Then a few stocks made fractional gains. Mining dropped fractionally. Martian Irrigation still was unexplainably low, as was Pluto Chemical and Asteroid Mining.
Trading through two brokers, Ben Wrail bought 10,000 shares of Venus Farms, Inc. when the market opened at 83½. A few minutes later they bought 10,000 shares of Spacesuits Ltd. at 106¼. The farm stocks dropped off a point. Spacesuits gained a point. Then suddenly both rose. In the second hour of trading the Venus stocks had boomed a full five points and Wrail sold. Ten minutes later they sagged. At the end of the day they were off two points from the opening. In late afternoon Wrail threw his 10,000 shares of Spacesuits on the market, sold them at an even 110. Before the close they had dropped back with a gain of only half a point over the opening.
Those were only two transactions. There were others. Spaceship Fabrication climbed three points before it fell and Wrail cashed in on that. Mercury Metals rose two points and crashed back to close with a full point loss. Wrail sold just before the break. He had realized a cool half million in the day's trade.
The next day it was a million and then the man who had always been a safe trader, who had always played the conservative side of the market, apparently sure of his ground now, plunged deeper and deeper. It was uncanny. Wrail knew when to buy and when to sell. Other traders watched closely, followed his lead. He threw them off by using different brokers to disguise his transactions.
Hectic day followed hectic day. Ben Wrail did not appear on the floor. Calls to his office netted exactly nothing. Mr. Wrail was not in. So sorry.
His brokers, well paid, were close-mouthed. They bought and sold. That was all.
Seated in his office, Ben Wrail was busy watching two television screens before him. One showed the board in the New York exchange. In the other was the image of Gregory Manning, hunched in a chair in Page's mountain laboratory back on Earth. And before Greg likewise were two screens, one showing the New York exchange board, the other trained on Ben Wrail's office.
"That Tourist stuff looks good," said Greg. "Why not buy a block of it? I happen to know that Chambers owns a few shares. He'll be dabbling in it."
Ben Wrail grinned. "It's made a couple of points, hasn't it? It's selling here for 60 right now. In 45 minutes it'll be quoted at 62."
He picked up a telephone. "Buy all you can of Tourist," he said. "Right away. I'll tell you when to sell. Get rid of whatever you have in Titan Copper at 10:30."
"Better let go of your holdings of Ranthoor Dome," suggested Greg. "It's beginning to slip."
"I'll watch it," promised Ben. "It may revive."
They lapsed into silence, watching the board in New York.
"You know, Greg," said Ben finally, "I really didn't believe all this was true until I saw those credit certificates materialize on my desk."
"Simple," grunted Greg. "This thing we've got can take anything any place. I could reach out there, grab you up and have you down here in a split second."
Ben sucked his breath in between his teeth. "I'm not doubting anything any more. You sent me half a billion two days ago. It's more than doubled now."
He picked up the phone again and spoke to his broker on the other end.
"Unload
