With my hysteria still on me, I sat for a time on the deck outside the chart-room with Snap. Then Carter summoned us back, and we sat listening while he, Balch and Dr. Frank went on with their conference. Listening to them I could not but agree that our best plan was to secure evidence which would incriminate all who were concerned in the plot. Miko, we were convinced, had been the Martian who followed Snap and me from Halsey’s office in Great-New York. George Prince had doubtless been the invisible eavesdropper outside the helio-room. He knew, and had told the others, that Grantline had found radium-ore on the Moon––that the Planetara would stop there on the way home.
But we could not incarcerate George Prince for being an eavesdropper. Nor had we the faintest tangible evidence against Ob Hahn or Rance Rankin. And even the purser would probably be released by the Interplanetary Court of Ferrok-Shahn when it heard our evidence.
There was only Miko. We could arrest him for the murder of Anita. But the others would be put on their guard. It was Carter’s idea to let Miko remain at liberty for a time and see if we could not identify and incriminate his fellows. The murder of Anita obviously had nothing to do with any plot against the Grantline Moon treasure.
“Why,” exclaimed Balch, “there might be––probably are––huge Martian interests concerned in this thing. These men here aboard are only emissaries, making this voyage to learn what they can. When they get to Ferrok-Shahn they’ll make their report, and then we’ll have a real danger on our hands. Why, an outlaw ship could be launched from Ferrok-Shahn that would beat us back to the Moon––and Grantline is entirely without warning of any danger!”
It seemed obvious. Unscrupulous, moneyed criminals in Ferrok-Shahn would be dangerous indeed, once these details of Grantline were given them. And so now it was decided that in the remaining nine days of our outward voyage, we would attempt to secure enough evidence to arrest all these plotters.
“I’ll have them all in the cage when we land,” Carter declared grimly. “They’ll make no report to their principals. The thing will end, be stamped out!”
Ah, the futile plans of men!
Yet we thought it practical. We were all doubly armed now. Explosive bullet-projectors and the heat-ray cylinders. And we had several eavesdropping microphones which we planned to use whenever occasion offered.
