"Narka trouble," Arl said, and George could see that the man's hands were trembling. "When my wife finds out, she'll be mad. When Narka's mad, she's very mad. And not just at me--she'll be on the warpath with you, too. She'll come here and--" "How can she come here, without your call?" "Oh, she'll find a way. Getting back is the difficult part. Please, George." "No. No, I don't think so. Myra started all this, not me. I told her to stop but she didn't want to. Now I think I'll let the two of you stew in your own juice for a while. You can't blame me. In a sense, I'm just an innocent bystander who happens to be a top-flight catalyst. But this could be amusing. I'll just let things stand." Arl turned to Myra. "Myra, do you want me to go back?" "Yes. Yes, I suppose so. You know more about this than we do, but my husband can be so obstinate--" "I'm not being obstinate. This was all your idea, and now I want to see what happens." Arl said, "There'll be quite a mess. Not only will Narka be angry with us, but the call will be coming through from all over, and none of our subjects can go over without my permission. You know what that means?" George asked him what. "That means that there'll be a lot of situations where poltergeists should have appeared, sort of like the old _deux ex machina_ of your early literature, only they won't. That, my friend, will cause a mess." George laughed. "I don't know. I've known a lot of people to get along well enough without your poltergeists. Everyone I've ever known, in fact. All my life." Myra shrugged helplessly. "Honest, Arl, I'm sorry. It's just that George is so ordinary." George scowled. He had been on the verge of relenting. He definitely had been on the verge of relenting. But that did it. He wouldn't relent now. "Can't you make him?" Myra demanded. "No. That's the difficulty. I can't. The caller must either be unaware or willing, and your husband is neither. There isn't a thing I can do about it until he changes. Ordinarily, I could do many things so that he'd see it our way--but that would necessitate popping in and out of the fourth dimension, and without George's help, I can't do that. It all rests with George." "Well, maybe we can _make_ him cooperate." "How do you mean, make him?" "I mean physically. There are two of us and one of him and maybe we can make him." * * * * * Myra advanced, and Arl was a little slower, but presently he got the idea, and he too came toward George. "Stay back," George warned. "Keep away from me or I'll never change my mind, and then you'll be stuck here forever." "He's right," Arl said. "No, he's not. We can make him. We can force him to change his mind."
