ONE-SHOT You here is a one-shot gamble right?" "And it's my guess that we're never going to get the answer by Ludmilla laid an egg in New York harbor, Abner Longmans ("One-Shot") Braun was in the city going about his normal business, which was making another million Ludmilla tale at the pay-off, working back to the hook, and winding up with a sheaf of background facts to feed into the computer for Next Time. It's Oing , oing ... "Try the Geiger." barely large enough to be visible at all, a black Homburg all perfectly won't make that much difference. How did you find out about this egg in the first place?" Ludmilla egg was buried among a lot of other crates in the dump-cell of the hold—" "What's a dump cell?" "It's a sea lock for getting rid of We don't know what it is. It may be a hell-bomb, or it may be just somebody's old laundry. Obviously we've got to find out which—and we want dangerous cargo. The bottom of it something out in the harbor. "Well, there was a timer on the dump-cell floor, set to drop the egg you to tell us." when the ship came up the river. That worked fine, but the automatic while the cell's open, didn't. At least they didn't do a thorough job. The Ludmilla saying: "What does it look like?" "It's just a lump of something, Dr. Hadamard. Can't even tell its shape—it's buried too deeply in the Ludmilla really laid an egg or not." "That's what I keep trying to explain to you, Dr. Harris. We don't know what she dropped and we haven't any way of finding out. It could be a bomb—it could be anything. We're sweating everybody on board the ship now, but it's my guess All right, maybe it's got a clockwork fuse that didn't break with the impact. Or a gyroscopic fuse. Stick a stethoscope on it and see if you pick up a ticking or anything that sounds like a motor running." to Braun. "As you can see, we're stymied. This is a long shot, Mr. Braun. One throw of the dice—one show-down hand. We've got to have an expert call it for us—somebody But this makes a difference. If I guess wrong—" "Then we're all dead ducks. But why should you guess wrong? Your hunches have been working for sixty respectively. The titles were almost wrong, the outcome won't be any worse than if you don't try at all." to the present. "All right," he said. "I told you the truth, Andy. Remember that. So—is it a bomb or ain't it? That's what's up for grabs, right?" I nodded. He closed his eyes. An unexpected stab of pure fright went down my back. Without the eyes, Braun's face was a death mask. The water sounds and the irregular ticking of a Geiger counter oing ... bonk ... oing , oing seemed to spring out from the audio crushed in his hand. oing "All right," he said. "You guys wanted it this way. I say it's a bomb. " He stared at us for a moment more—and oing ... , phone down again. "Are you going your job like I did mine—get my wife and kids out of there—empty to duck out just like that? Remember, for the phone. "You're right, Mr. Braun. If it isn't already too late—" Cheyney shot out a hand and caught Anderton's telephone arm by "What d'you mean, 'wait a minute'? Haven't you already shot shielded that dump-cell is." "It isn't shielded at all," Anderton's voice said behind me. I hadn't prove anything. The egg might have carried sufficient shielding in itself. Or maybe the Commies didn't care squawked. "But Dr. Hadamard, if that sets it off—" "It won't go off. That's the one thing you can be sure it won't do." whether the crew was exposed or not. Or maybe there isn't any egg." "All that's possible," I admitted. "Unscrew the cap?" the audio "We're getting plenty of radiation now. Just a minute— Yeah. Dr. Hadamard, it's a bomb, all right. But it hasn't got a fuse. Now how could they have made a fool mistake like that?" "In other words, it's a dud," Joan said. "That's right, a dud." Dr. Harris, we've got to evacuate the city first of all! No matter whether it's a real egg or not—we can't take not being an egg!" "Don't move a man until you get the chance on it's Now, at last, Braun wiped his face, which was quite gray. "I told you a go-ahead from CIA," I said. "For test how our facilities would stand up in a real bomb-drop." "A real drop?" Anderton said. "Are you trying to say that CIA staged this? You ought to be shot, the whole pack of you!" a half million lives riding on it. I can't let you do it." right. We got word last month from our man in Gdynia that they were going to do it, and that the bomb would be on board the Ludmilla "No, not exactly," I said. "The all we know now, evacuating the city to miss. We wanted to find out just how long it would take us to figure out the nature of the bomb—which we didn't know in detail—after it was dropped here. So we had our Ludmilla right on the button as far as it went. We didn't ask you whether or not that object was a live bomb. We asked whether it was a bomb or not. You said it was, and you were right." The expression on Braun's face I found nothing but a faint It was too good a chance for us to was exactly like the one he had worn a racket-ridden union now formally extinct—although anyone he said grimly. "There are eight and may be just what the enemy wants us Joan had the divers unscrew the cap. In a real drop that would have resulted in a detonation, if the bomb was real we'd never risk it. That "And that means that you were the only person who did come through, Mr. Braun. If a real bomb-drop ever comes, we're going to have to have you here, as an active part of enemy's responsible for the drop, all lives." There was quite a long silence. All the equation stands for the moment when the shoestring broke.) steel all the way through." would double his guilt instead of salving it. It's the same way with the "Of course it isn't," Joan had said. "The next thing he'll do is go in for the Detroit slum area where he had been born—the plainest kind of symbolic suicide: Let's not have any more Abner Longmans Brauns born and falling. The audio went cloonck Ludmilla ... eight and a half million lives riding on it—" That put it up into Braun's normal operating area, all right. The opens right to Davy Jones. Standard Braun chuckled. "I still know a thing or two," he said. "What's the them, with orders to scorch it over to Braun without stopping to breathe bent over a seismograph, echo-sounding for the egg through the river bottom. If that even had a prayer of Manhattan stopped through their tubes would have blanked out any possible echo-pip from the egg. "Wild goose chase?" Joan said, scanning my face. "Not quite. I've got something, if I can just figure out what it is. Remember One-Shot Braun?" "Yes. What's he got to do with it?" amorphous black mass, jutting up from a foundation of even deeper black. "Is that operation getting you anywhere?" "Nothing's gotten us anywhere," Anderton interjected harshly. "We don't even know if that's the egg—the whole area is littered with crates. Harris, you've got to let me get that alert out!"
