"Karola, Karola," she said insistently.

"Karola. Okay. I'm Thor."

The violet eyes were sliding over him, taking in his big frame and long legs. Thor flushed a little, reading the frank admiration in her eyes. Felling logs and playing an all-Conference grade of tackle on the football team had built up an already good physique. But the years of logging and football and fighting had left little time for women. And Karola was a woman among women.

She laughed at him, and said something.

"We'd better take a look around," he said, carefully looking over her golden head.


He was staring at grey rock as he spoke. Above it a shape took form out of empty air. It was a man, standing and staring at them. It was as though he had slid sideways out of another dimension. The man watched them with unblinking eyes. He fumbled at a red jewel that hung on a chain at his chest.

An instant later, the man was gone.

"A swell place this is, where a man appears and disappears right in front of you," he said disgustedly. "If they can come and go when and where they please, what chance have we?"

Riotous ideas of invisible men swarming about him and overcoming him capered through his brain. Unconsciously he tensed, preparing for trouble. But nothing happened. Slowly he relaxed.
