"Now, whatever we may have thought at first about this rocket having originated on Mars, we know now that LaRauche manufactured it himself. He had the brain power necessary to create this fantasy in mechanism, and the means and method of carrying out his motive, which was to bring my brother Henry to shame."

"All of which stirred the popular imagination, and increased the circulation of the Daily Recorder half a million," McGinity interjected.

"Well," Chief Meigs drawled, "all I got to say is this. If making screws that go in backwards is not the act of a lunatic, then I'm crazy myself."

For several hours, McGinity and I remained at the police station, occupying ourselves piecing together from this and that all the information at our command; and at the end, it was as clear as daylight that we knew no more about the actual perpetration of the hoax than we did twenty-four hours back. The impression we both had gained was that tragedy had been obtruded into LaRauche's suave scheme that was shockingly disturbing, but had nothing whatever to do with clearing up the case.

There was little or nothing at the LaRauche home for the police to go on with. No trace of the revolver that had pierced Orkins' heart with its deadly bullet; no firearms of any sort, in fact. Mrs. LaRauche heightened the mystery by declaring her husband had an inherent fear of the use of firearms, as he had of fire, and had never owned a revolver. Nor was any sort of weapon discovered during the inspection of his laboratory, or workrooms, in the observatory and hangar, in which he operated outside his dwelling. No evidence even was found that would in the slightest degree incriminate him in the Martian fraud.

The city papers had come by plane, after midnight, and I read them all with interest. McGinity, fed up on the story, waved them away. They contained a very full account of what had occurred at the castle, Orkins' mysterious death, and LaRauche's escape by plane.

About three o'clock, I succeeded in reaching Olinski on the telephone, at his city home, and he was so upset over the whole affair, as reported in the papers, that at first all he could seem to do was to sputter into the mouthpiece.

"I fear, my dear Mr. Royce," he managed to say, finally, "that you and that reporter fellow have made a great mistake—a serious error. You have found nothing to prove that the radio message, and the rocket, did not originate in Mars, now, have you?"

"Nothing," I replied, "except that water-mark we found in the scroll."

"That proves nothing," he fairly shouted. "Some utterly unscrupulous and wicked person may have changed that scroll after it passed out of my possession."
