"Yes."

"Why?"

Suddenly he began to cough. Breath came hard. She held the oxygen mask in readiness. He shook his head, not wanting it.

"Why?" he asked again.

"It would be a long story. Perhaps I'll tell you tomorrow."

A new thought, cloaked in sudden fear, entered his murky consciousness. "Tell me, will—will I be well again? Will I be able to walk?"

He lay back then, panting, exhausted.

"You have nothing to worry about," the girl said softly. Her cool hand touched his hot forehead. "Rest. We'll talk later."

His eyes closed and breath came easier. He slept.

When he next awoke, his gaze turned first to the window. There was light outside, but he had no way of knowing if this was morning, noon or afternoon—or on what planet.
