In spite of himself Grant could not hide a sudden grin of relief. The man was mad, to think of pitting a few liners against armored battle craft. Miro saw that grin.
"You think I'm mad, don't you?" he gloated. "Just listen to this, then. We have found a substance that no ray, no electro-bullet can penetrate. Every ship will be coated with it. And the Gorm here"—he pointed to the oily lake—"will draw your proud cruisers down to destruction, or thrust them far out into the uncharted spaces, helpless, just as it pleases us. You wonder how it works? Look! Now it attracts, and powerfully. But when I reverse the current passing through it like this"—he leaned over and pulled a switch set in the rock right by the edge—"it repels everything. We'll just stand off in space and pick off your proud warships one by one, without a scratch to ourselves. See?" He fairly hissed the last word.
Grant saw, and the cold sweat burst out on his forehead. His brain raced desperately in a vain effort to find some way out, some method of foiling this beast.
"You sure talk big, Miro," he said in bored fashion, feigning indifference; "but it means nothing to me. The point is, what do you intend doing with us?"
The Ganymedan's lips writhed. "Nothing at all to your pretty friend," he leered. "I have plans for her. But as for you—see these creatures all about?"
"Well?"
"You are going to be one of them. They are passengers and crews who had the misfortune to be alive when the captured ships were sprayed with our gas. It does not kill. Oh, no! It just numbs their faculties, paralyzes them. Then our surgeons get busy. They know how to remove the memory and reasoning areas of the brain and leave just machines, automata, to do our bidding. Clever, aren't they? When Earth is captured, I intend subjecting all your damned breed to the operation. They make very willing slaves, I've found. Two blasts on this toy"—he raised the whistle to his lips—"and an Earth-Doora comes for you."
Nona sprang forward. "No, no, Miro. Please do not touch Mr. Pemberton. I'll—I'll—"
"What will you?" The Ganymedan's pig-eyes devoured her.
