"I used to. I might remember it under hypnosis, I suppose. Why? Do you want me to translate something?"

"Not exactly. We were thinking of sending you on an expedition to the trailmen themselves."

(In the darkened office, watching Jay's startled face, I thought; God, what an adventure! I wonder—I wonder if they want me to go with him?)

Forth was explaining: "It would be a difficult trek. You know what the Hellers are like. Still, you used to climb mountains, as a hobby, before you went into Medical—"

"I outgrew the childishness of hobbies many years ago, sir," Jay said stiffly.

"We'd get you the best guides we could, Terran and Darkovan. But they couldn't do the one thing you can do. You know the trailmen, Jay. You might be able to persuade them to do the one thing they've never done before."

"What's that?" Jay Allison sounded suspicious.

"Come out of the mountains. Send us volunteers—blood donors—we might, if we had enough blood to work on, be able to isolate the right fraction, and synthesize it, in time to prevent the epidemic from really taking hold. Jay, it's a tough mission and it's dangerous as all hell, but somebody's got to do it, and I'm afraid you're the only qualified man."

"I like my first suggestion better. Bomb the trailmen—and the Hellers—right off the planet." Jay's face was set in lines of loathing, which he controlled after a minute, and said, "I—I didn't mean that. Theoretically I can see the necessity, only—" he stopped and swallowed.

"Please say what you were going to say."
