But the rest of the Secret Agents, save to freeze into immobility when the hated voice spoke, gave no sign. They had worries of their own, for no instructions had been given that they bring their own loved ones into the sanctuary of the Secret Room.
As though answering the thoughts of the others, the hated voice spoke again.
"I regret that I cannot arrange for sanctuary for the loved ones of all of you, for you are gallant antagonists; why save the few, when the many must perish? For I know you will not surrender, however much I have proved to you that I am invincible. But Charmion Kane must be saved."
"God!" whispered Kleig. "God!"
Then spoke General Munson.
"I think this ray which the Moyenites use is a variation of the principle used in the intricate machinery of Professor Maniel, though how they render it visible I do not know. But it doesn't matter, and may be only a blind! You'll note that when the black streak, or the golden ray, strikes anything that thing instantly disintegrates. A certain pitch of resonance will break a pane of glass. It's a matter of vibration, solely, wherein the molecules composing any object animate or inanimate, are hurled in all directions instantaneously.
"Professor Maniel's apparatus, the Vibration-Retarder, is able to recapture the vibrations, speeding outward endlessly through space, and to reconstruct, and draw back to visibility the objects destroyed by this visible vibratory ray, whatever it is. This problem, then, falls into the province of Professor Maniel!"
Through the heart and soul of Prester Kleig there suddenly flowed a great surge of hope.
"General Munson, if you will operate the machinery of the Vibration-Retarder, I wish to talk with Professor Maniel!"
