"Wait a minute." McCarthy stepped between them before their angry glances at each other could be translated into action. "We're all twins. I mean triplets. I mean--Sit down. I got somethin' to tell you." They all squatted slowly, suspiciously. Four chaws of tobacco later, there was a little circle of dark nicotine juice all around them. McCarthy was breathing hard, all three of him. "So it's like I'm McCarthy I because I've seen this thing through up to where I stop McCarthy II from going back to get the note that McCarthy III wants from Ruddle." The man with the camera rose and the others followed. "The only thing I don't get," he said finally, "is that I'm McCarthy III. Seems to me it's more like I'm McCarthy I, he's McCarthy II--that part's right--and _you're_ McCarthy III." "Uh-uh," McCarthy II objected. "You got it all wrong. The way I look at it--now see if'n this doesn't sound right--is that _I'm_ McCarthy I, you're--" "Hold it! Hold it!" The two men who had been fighting turned to McCarthy I. "I _know_ I'm McCarthy I!" "How do you know?" they demanded. "Because that's the way Professor Ruddle explained it to me. He didn't explain it to you, did he? I'm McCarthy I, all right. You two are the stubbornest bindlestiffs I've seen and I've seen them all. Now let's get back." "Wait a minute. How do I know I still ain't supposed to move this rock? Just because you say so?" "Because I say so and because Professor Ruddle says so in that note I showed you. And because there are two of us who don't want to move it and we can knock you silly if'n you try." At McCarthy II's nod of approval, McCarthy III glanced around reluctantly for a weapon. Seeing none, he started back to the time machines. McCarthys I and II hurried abreast. "Let's go in mine. It's closest." They all turned and entered the machine of McCarthy I. "What about the checks? Why should you have three checks and McCarthy II have two while I only got one? Do I get my cut?" "Wait'll we get back to the professor. He'll settle it. Can't you think of anythin' else but money?" McCarthy I asked wearily. "No, we can't," McCarthy II told him. "I want my share of that third check. I got a right to it. More'n this dopey guy has, see." "O.K. O.K. Wait'll we get back to the lab." McCarthy I pushed down on the chronotransit. The island and the bright sunlight disappeared. They waited. * * * * * Darkness! "Hey!" McCarthy II shouted. "Where's the lab? Where's Professor Ruddle?" McCarthy I tugged at the chronotransit. It wouldn't move. The other two came over and pulled at it too. The chronotransit remained solidly in place. "You must've pushed down too hard," McCarthy III yelled. "You busted it!" "Yeah," from McCarthy II. "Who ever told you that you could run a time machine? You busted it and now we're stranded!"
