Van Huys chuckled, and Joe Sanders grinned.

"Don't look like much from topside, eh, Krassner? I figgered it wouldn't. The old man's a fox. He spent more than twenty years givin' this hide-out the damnedest coat of natch'ral camouflage you ever seen."

"Old man?" said Krassner curiously. "Camouflage?"

Maureen touched my arm. She whispered, "Maybe you had better not tell him, Brian. It's our secret—"

I started to tell her what the hell. He was one of us, and there were mighty few of us left. We needed all the men we could get. And Krassner looked like a man.
