Halder said patiently, "It's not an impossibility. We've been forced to spend most of the past year and a half gathering information, studying the intricate functioning of this gigantic civilization—so many things that our mentors on Kalechi either weren't aware of or chose not to tell us. And we haven't done too badly, Kilby. We're prepared now to conduct the search for the group in a methodical manner. Nineteen hours in space, and we'll be on another world, under cover again, with new identities. Why shouldn't we continue with the plan until ..."

Kilby interrupted without change of expression. "Until we hear some day that billions of human beings are dying on the Federation's worlds?"

Halder kept his eyes fixed on the traffic pattern ahead. "It won't come to that," he said.

"Won't it? How can you be sure?" Kilby asked tonelessly.

"Well," Halder asked, "what else can we do? You aren't suggesting that we give ourselves up—"

"I've thought of it."

"And be picked apart mentally and physically in the Federation's laboratories?" Halder shook his head. "In their eyes we'd be Kalechi's creatures ... monsters. Even if we turn ourselves in, they'll think it's some trick, that we'd realized we'd get caught anyway. We couldn't expect much mercy. No, if everything fails, we'll see to it that the Federation gets adequate warning. But not, if we can avoid it, at the expense of our own lives." He glanced over at her, his eyes troubled. "We've been over this before, Kilby."

"I know." Kilby bit her lip. "You're right, I suppose."

Halder let the cab glide out of the traffic lane, swung it around towards the top of a tall building three miles to their left. "We'll be at the club in a couple of minutes," he said. "If you're too disturbed, it would be better if you stayed in the car. I'll pick up our flighthiking outfits and we can take the cab on to the city limits before we dismiss it."

Kilby shook her head. "We agreed we shouldn't change any details of the escape plan unless it was absolutely necessary. I'll straighten out. I've just let this situation shake me too much."
