He caught her trembling hand again, waited.

"The robot police took me to some agency of the Corporation," her dry weary whisper resumed. "There they put me on a larger ship, that was laden with the loot of planets that the robots had vanquished. That carried me to some other world. The robot nurses drugged me as we landed. When I came to, we were on another ship, out in space again.

"That ship took me to Mystoon!"

She lay motionless for a long time, then, with her eyes closed again. Her breath was a faint dry sobbing sound. Softly, the Earthman brushed the glistening tangle of yellow hair back from her forehead.

"Mystoon?" he asked at last. "What's it like, Verel?"

The blue eyes opened, somber pools of dread.

"Don't ask me, Kel," she whispered. "I can't endure to talk of Black Mystoon. Not now. No more than I must—Malgarth's there. It has been his hidden fortress for half a million years. It's guarded well. I think I'm the first human being to escape it—if any had been taken there before me. I did it only because I had to find you, Kel. Had to!"

She clutched his hand again, and sighed.

"But still Malgarth has the Stone, on Mystoon. He has preserved it, trying to find in it the secret of his own mortality. I saw it once, while they were making that—that copy of me."
