“That would get you there,” I allowed.

She shook her head. “Oh, no. The fifty dollars is for you. You know our name, Vardas? You know we are married? So there is no question of morals, we are very high in morals, only all we want is to do our work and live in private, Carl and me, and we think—”

Having heard the clatter of Wolfe’s elevator descending from the plant rooms on the roof, I had known an interruption was coming but had let her proceed. Now she stopped as Wolfe’s steps sounded and he appeared at the door. Carl and Tina both bounced to their feet. Two paces in, after a quick glance at them, Wolfe stopped short and glowered at me.

“I didn’t tell you we had callers,” I said cheerfully, “because I knew you would be down soon. You know Carl, at the barber shop? And Tina, you’ve seen her there too. It’s all right, they’re married. They just dropped in to buy fifty bucks’ worth of—”

“Forget it. He’s only mad at me, which is chronic. What do you want to go to Ohio for?”

“Maybe not Ohio.” She tried to smile again. “It’s what I said, we love this country and we want to go more into it — far in. We would like to be in the middle of it. We want you to tell us where to go, to help us—”

“No, no.” I was brusque. “Start from here. Look at you, you’re both scared stiff. What’s the danger Carl mentioned?”
