"I will be waiting," she said, and did not move as I slipped out between two trunks of the banyan-like tree.
It was daylight and the silvery grayness overhead was palely luminous. I headed for the nearest rampart of fog.
Lhar was right. Each time I went into that cloudy fog barrier I was blinded. I crept forward step by step, glancing behind me at my footprints in the snow, trying to keep in a straight line. And presently I would find myself back in the valley....
I must have tried a dozen times before giving up. There were no landmarks in that all-concealing grayness, and only by sheerest chance would anyone blunder into this valley—unless hypnotically summoned, like the Indio girls.
I realized that I was trapped. Finally I went back to Lhar. She hadn't moved an inch since I had left, nor had the robot, apparently.
"Lhar," I said. "Lhar, can't you help me?"
The white flame of the flower was motionless, but the robot's cilia moved in quick signals. Lhar moved at last.
"Perhaps," her thought came. "Unless both induction and deduction fail, my robot has discovered a chance for you. The Other can control your mind through emotions. But I, too, have some power over your mind. If I give you strength, wall you with a psychic shield against intrusion, you may be able to face the Other. But you cannot destroy it unless it is in its normal shape. The Indio girls must be killed first...."
"Killed?" I felt a sense of horror at the thought of killing those poor simple native girls.
"They are not actually alive now. They are now a part of the Other. They can never be restored to their former life."
