"And if I'd come alone?"

"But you wouldn't have—"

"Walt, I would have. You couldn't have kept me. So, regardless of whether you blame yourself, you need not. If anybody is to blame, call it Kingman. And Walt, remember? I've just found you. Can you imagine—well, put yourself in my place—how would you feel if I'd walked out of your office and dropped out of sight? I'm going to say it once and only once because it sounds corny, Walt, but I'd rather be here and knowing than to be safe and forever wondering. And so long as there is the breath of life in us, I'll go on praying for help."

Walt put his arms around her and held her gently. Christine kissed him lightly. "Now I'm going to curl up on that couch," she said. "Don't dare let me sleep more than six hours."

"I'll watch."

"And I'll measure time for you. Once we start sleeping the clock around, we're goners."

Christine went to the couch and Walt piled the available covers on after he checked the operation of the power tube that furnished heat for her suit. He turned it up a bit, and then dimmed the light.

For Walt there was no sleep. He wandered from room to room in sheer frustration. Given anything of a partially technical nature and he could have made something of it. Given a tool or two or even a few items of kitchen cutlery and he might have quelled his restlessness in working toward some end. But to be imprisoned in a small house that was rapidly dropping toward zero degrees Kelvin without a book, without a knife or fork or loose bit of metal anywhere was frustration for the technical mind.

Mark Kingman, of course, had been quite afraid of just that and he had skinned the place bare of everything that could possibly be used. Kingman even feared a loose bit of metal because metal struck against metal can produce sparks that will light a fire.

There was nothing at all but himself—and Christine.
