"I don't feel I'm giving away any government secrets," Paul said, "when I tell you that the bastions of our defenses are not erected at the Actors' Studio." "Listen, pal, you lemme spy the way I wanna an' I'll letcha act the way you wanna." Paul was disturbed by this change in Ivo because, although he had always tried to steer clear of social involvement, he could not help feeling that the young alien had become in a measure his responsibility--particularly now that he was a teen-ager. Paul would even have worried about Ivo, if there hadn't been so many other things to occupy his mind. First of all, the producers of _The Holiday Tree_ could not resist the pressure of an adoring public; although the original star sulked, three months after the play had opened in New York, Paul's name went up in lights next to hers, _over the title of the play. He was a star._ That was good. But then there was Gregory. And that was bad. Gregory was Paul's understudy--a handsome, sullen youth who had, on numerous occasions, been heard to utter words to the effect of: "It's the part that's so good, not him. If I had the chance to play Eric Everard just once, they'd give Lambrequin back to the Indians." Sometimes he had said the words in Paul's hearing; sometimes the remarks had been lovingly passed on by fellow members of the cast who felt that Paul ought to know. * * * * * "I don't like that Gregory," Paul told Ivo one Monday evening as they were enjoying a quiet smoke together, for there was no performance that night. "He used to be a juvenile delinquent, got sent to one of those reform schools where they use acting as therapy and it turned out to be his _metier_. But you never know when that kind'll hear the call of the wild again." "Aaaah, he's a good kid," Ivo said. "He just never had a chanct." "Trouble is, I'm afraid he's going to _make_ himself a chanct--chance, that is." "Aaaah," retorted Ivo, with prideful inarticulateness. However, when at six-thirty that Friday, Paul fell over a wire stretched between the jambs of the doorway leading to his private bathroom and broke a leg, even Ivo was forced to admit that this did not look like an accident. "Ivo," Paul wailed when the doctor had left, "what am I going to do? I refuse to let Gregory go on in my place tonight!" "Y'gonna hafta," Ivo said, shifting his gum to the other side of his mouth. "He's y'unnastudy." "But the doctor said it would be weeks before I can get around again. Either Gregory'll take over the part completely with his interpretation and I'll be left out in the cold, or more likely, he'll louse up the play and it'll fold before I'm on my feet." "Y'gotta have more confidence in y'self, kid. The public ain't gonna forgetcha in a few weeks." But Paul knew far better than the idealistic Ivo how fickle the public can be. However, he chose an argument that would appeal to the boy. "Don't forget, he booby-trapped me!"
