"Drink this."

Bart touched his lips to the glass, made a face and put it away. "Thanks, but I don't drink."

"Call it medicine, you'll need something," Raynor Three said crossly. "I've got a lot to tell you, and I don't want you going off half-primed in the middle of a sentence. If you'd rather have a shot of tranquilizer, all right; otherwise, I prescribe that you drink what I gave you." He gave Bart a quick, wry grin. "I really am a medic, you know."

Feeling like a scolded child, Bart drank. It burned his mouth, but after it was down, he felt a sort of warm burning in his insides that gradually spread a sense of well-being all through him. It wasn't alcohol, but whatever it was, it had quite a kick.

"Thanks," he muttered. "Why are you taking this trouble, Raynor? There must be danger—"

"Don't you know—" Raynor broke off. "Obviously, you don't. Your mother never said much about your Mentorian family tree, I suppose? She was a Raynor." He smiled at Bart, a little ruefully. "I won't claim a kinsman's privileges until you decide how much to trust me."

Raynor Three settled back.

"It's a long story and I only know part of it," he began. "Our family, the Raynors, have traded with the Lhari for more generations than I can count. When I was a young man, I qualified as a medic on the Lhari ships, and I've been star-hopping ever since. People call us the slaves of the Lhari—maybe we are," he added wryly. "But I began it just because space is where I belong, and there's nowhere else that I've ever wanted to be. And I'll take it at any price.

"I never questioned what I was doing until a few years ago. It was your father who made me wonder if we Mentorians were blind and selfish—this privilege ought to belong to everyone, not just the Lhari. More and more, the Lhari monopoly seemed wrong to me. But I was just a medic. And if I involved myself in any conspiracy against the Lhari, they'd find it out in the routine psych-checking.

"And then we worked out how it could be done. Before every trip, with self-hypnosis and self-suggestion, I erase my own memories—a sort of artificial amnesia—so that the Lhari can't find out any more than I want them to find out. Of course, it also means that I have no memory, while I'm on the Lhari ships, of what I've agreed to while I'm—" His face suddenly worked, and his mouth moved without words, as if he had run into some powerful barrier against speech.
