Ellen Estabrook sighed softly as though with relief. Her hands went up to remove her hat, which she placed on a chair in a corner of the hellish laboratory. She removed her light coat and arranged her hair with skilled fingers. But even as she moved around the room of the long table her eyes stared vacantly into space. She was as much a puppet of Caleb Barter as were Stanley, Morton and Cleve. But, mercifully, she did not know it.
Barter studied her for several moments; his eyes squinted. He was making sure that she was not duping him with pretense. Satisfied at last be turned his eyes away from her. He stepped to the porcelain slab set in the bronze wall of his laboratory and looked at the push-buttons marked “C-3” and “E-5”. The red lights were on, indicating that the two puppets controlled by these two keys were returning toward their master. The lights had been green when Barter had begun his conversation with Ellen Estabrook, indicating that the two puppets were still going away. With a tremendous effort of will he had given them sufficient mental stimulus to keep them traveling without his direct will for the few minutes he would require for Ellen.
Now, however, he quickly donned the metal cap and the little ball, and inserted into the orifice in his cap the swinging key which connected by chain with the key which fitted into the slot under the button marked “C-3”.
He had returned to his puppets just in time. “C-3” was Cleve, who was driving the car sent out to bring in the Colombian ape. As Barter got in touch with the car it narrowly averted a crash with a police car ... and the perspiration broke forth afresh on the body of Barter as he resumed control of his puppets.
The second creature, in the front seat of the car, was Morton, and it didn’t matter particularly about him as he was not driving. But Morton was now becoming all ape. Barter did not wish to use any more of his mental energy than was necessary. He contented himself by sending his will into Cleve, who began at once to drive like a master. Whenever Morton, beside him, showed an inclination to jump out of the car or otherwise interfere with Cleve in his work, Barter had but to express the thought, and Cleve either pulled him back to his place beside him, or gave him a walnut from his pocket.
Barter could as easily have had them change places, since he assumed control of either at will, or could have controlled a score simultaneously. But that would have required additional thought stimulus, and he wished to conserve his mental energies for the work which yet faced him.
Once he switched his attention from the heliotube which controlled Cleve––and through which, concurrently, he saw everything that transpired near Cleve, because his televisory apparatus and his radio control were co-workers on almost identical vibratory waves––to the area of Manhattan immediately surrounding his own neighborhood.
“Hmm,” he said to himself, “the police are getting too close. As soon as I have completed my labors to-night I shall destroy some of them as a warning to others to keep their distance.”
