Graff said slowly: "We will give them a few hours of the Red vibrations--to-night and to-morrow perhaps, and then broadcast from the purple globe--restore normality." He added grimly: "We will see then what they say, Peter." The two globes were white, opaque and silent. Graff turned to a switch. For the first time that evening Zetta spoke; an involuntary cry of protest. "No! Graff--no!" She gripped him, but he thrust her roughly aside. I was tense; I think then I was about to leap upon Graff. But from the hand of the black-robed man a weapon was pointing quietly, menacingly at me. Graff's face was grimly inscrutable. He reached up suddenly and threw the switch. The dim light from somewhere in the room faded and vanished. A crimson glow from one of the globes took its place; the other globe stood milk-white, silent, alert. A humming. From the grid over the active globe a faint red beam was streaming. It spread; it deepened; it streamed out through the solid black wall of the room. I stared after it. Sidewise--upward; I seemed to be gazing out into a black illimitable distance, red-tinted. Long unearthly vibrations, broadcast now around our world! They were already around and back again and starting anew. "Come," said Graff's voice abruptly. "That's all." The black-masked operator was seated at his little table, watching his dials. The red globe had settled to its steady hum as we left the room. Strangely brief, undramatic scene! I sensed that Graff had made it so--a cloak to hide what emotions sweeping him, only he would ever know. A matter-of-fact casualness. Yet I have never witnessed a scene of such potential horror. A small stone house, black-vaulted room with its lone, black-garbed man. Just a single small globe, faintly humming, glowing crimson. But I knew that within a day or so our great earth would be at its mercy! Back on Xenephrene, in Garla that evening at the Stadium, there had followed a night of confusion. With the Infra-red Control stolen, the Garlands were in a panic. The frightened people had rushed for the grottos; by the time the authorities were able to bring order, the night had passed. At dawn, pursuit had started for the Braun city. Too late. Graff's expedition had left for earth. The Brauns remaining on Xenephrene learned now their leader's duplicity. They, too, were stricken with fear and horror. There is an old saying on earth, "When the devil is sick, the devil a monk would be!" The Garland authorities were very ready to listen to father now! They sent at once for him and Dan and Freddie. They begged his advice; there was nothing they would not do to help him, if only he could suggest a way to get back the Control.
