"Did I honest-to-God study medicine? It's the last thing I'd think about. It's an honest trade, I guess, but I've never been that intellectual."

"You—or rather, Jay Allison is a specialist in Darkovan parasitology, as well as a very competent surgeon." Forth was sitting with his chin in his hands, watching me intently. He scowled and said, "If anything, the physical change is more startling than the other. I wouldn't have recognized you."

"That tallies with me. I don't recognize myself." I added, "—and the queer thing is, I didn't even like Jay Allison, to put it mildly. If he—I can't say he, can I?"

"I don't know why not. You're no more Jay Allison than I am. For one thing, you're younger. Ten years younger. I doubt if any of his friends—if he had any—would recognize you. You—it's ridiculous to go on calling you Jay2. What should I call you?"

"Why should I care? Call me Jason."

"Suits you," Forth said enigmatically. "Look, then, Jason. I'd like to give you a few days to readjust to your new personality, but we are really pressed for time. Can you fly to Carthon tonight? I've hand-picked a good crew for you, and sent them on ahead. You'll meet them there. You'll find them competent."


I stared at him. Suddenly the room oppressed me and I found it hard to breathe. I said in wonder, "You were pretty sure of yourself, weren't you?"

Forth just looked at me, for what seemed a long time. Then he said, in a very quiet voice, "No. I wasn't sure at all. But if you didn't turn up, and I couldn't talk Jay into it, I'd have had to try it myself."
