"Yes, I've heard of him," Manthis said after he had been informed of the encounter. "A naturalized Russian. Used to do quite a bit of valuable work in various fields of physics. But he was some sort of radical—seems to me an old-fashioned anarchist—and not popular. He dropped out of sight several years ago. I presumed he was dead."
They soon had the new equipment installed and again began exploring the wave bands, beginning with the comparatively lengthy ones and working down into those only slightly longer than light. It was tedious work, but all were by now as adept as Jack in combing the ether and their task progressed rapidly. Despite the labor, however, nothing could be heard. There was only the universal, breathless silence. At times they moved to the commercial bands and tried to pick up the stations they had heard on the previous day, but even there they met with failure.
By the evening of the third day they had left the wave bands which could be measured in meters and were exploring those strange and almost wholly uncharted depths of the ether which must be calculated in centimeters. There at last luck favored them. It was Jack who caught a strange pulsating tone on the three-centimeter band. It rose and fell, rose and fell, then died away like the keening of a lost soul.
"Listen," he whispered. "Plug in here. I've found something."
June and the doctor followed his instructions. Delicately fingering the coils, Baron picked up the sound again, only to lose it. Then it came once more. This time he followed it as it changed to the five centimeter band. Back and forth it went as though weaving an intricate and devilish web.
"What do you make of it?" queried the doctor at last.
"Don't know." Jack bit his lips. "It's no natural phenomenon, I'll swear. Somebody is manipulating a broadcasting station of terrific power not far from here and playing with that wave as a helmsman brings a sailing ship into the wind and lets her pay off again."
"What do we do now?" The little chemist, finding his theory apparently confirmed, was at a loss. "Could we wreck that station?"
"Fat chance!" The engineer laughed bitterly as he reached for a cigarette. "Whoever has conceived that bit of hellishness is well guarded. The three of us wouldn't have a ghost of a show. What I can't understand is—"
