Even before his foot had left the floor in free motion, however, DuQuesne realized exactly what had happened. His keen eyes saw the flash of blinding incandescence announcing a world's ending and sent to his keen brain a picture; and in the instant of perception that brain had analyzed that picture and understood its every implication and connotation. Therefore he only grinned sardonically at the phenomena which left the slower-minded Loring dazed and breathless.
He continued to grin as the battleship hurtled onward through the void at a pace beside which that of any ether-borne wave, even that of such a Titanic disturbance as the atomic explosion of an entire planet, was the veriest crawl.
At last, however, Loring comprehended what had happened. "Oh, it exploded, huh?" he ejaculated.
"It most certainly did." The scientist's grin grew diabolical. "My statements to them came true, even though I did not have anything to do with their fruition. However, these events prove that caution is all right in its place—it pays big dividends at times. I'm very glad, of course, that the Fenachrone have been definitely taken out of the picture."
Utterly callous, DuQuesne neither felt nor expressed the slightest sign of pity for the race of beings so suddenly snuffed out of existence. "Their removal at this time will undoubtedly save me a lot of trouble later on," he added, "but the whole thing certainly gives me furiously to think, as the French say. It was done with a sensitized atomic copper bomb, of course; but I should like very much to know who did it, and why; and, above all, how they were able to make the approach."
"Personally, I still think it was Seaton," the baby-faced murderer put in calmly. "No reason for thinking so, except that whenever anything impossible has been pulled off anywhere that I ever heard of, he was the guy that did it. Call it a hunch, if you want to."
"It may have been Seaton, of course, even though I can't really think so." DuQuesne frowned blackly in concentration. "It may have been accidental—started by the explosion of an ammunition dump or something of the kind—but I believe that even less than I do the other. It couldn't have been any race of beings from any other planet of this system, since they are all bare of life, the Fenachrone having killed off all the other races ages ago and not caring to live on the other planets themselves. No; I still think that it was some enemy from outer space; although my belief that it could not have been Seaton is weakening.
"However, with this ship we can probably find out in short order who it was, whether it was Seaton or any possible outside race. We are far enough away now to be out of danger from that explosion, so we'll slow down, circle around, and find out whoever it was that touched it off."
He slowed the mad pace of the cruiser until the firmament behind them once more became visible, to see that the system of the Fenachrone was now illuminated by a splendid double sun. Sending out a full series of ultra-powered detector screens, DuQuesne scanned the instruments narrowly. Every meter remained dead, its needle upon zero; not a sign of radiation could be detected upon any of the known communicator or power bands; the ether was empty for millions upon untold millions of miles. He then put on power and cruised at higher and higher velocities, describing a series of enormous looping circles throughout the space surrounding that entire solar system.
Around and around the flaming double sun, rapidly becoming first a double star and then merely a faint point of light, DuQuesne urged the Fenachrone battleship, but his screens remained cold and unresponsive. No ship of the void was operating in all that vast volume of ether; no sign of man or of any of his works was to be found throughout it.
