The group of intelligence officers who heard the report was deadly serious. First it held a whispered conference behind closed doors. Then the officers emerged again to question Neil, Bull Mike and Sukune, one at a time. The three were sworn not to discuss their adventure, even among themselves, and directed to return to their quarters.
The Martian prisoner also repeated his story. Subjected to the truth-rays, which, properly administered, eliminate the power of lying, he answered all questions in substantially the same manner as before. He was prevailed upon to draw diagrams of the artificial planetoid in which his fellows were whirling ever nearer to their opposition with Earth.
Finally he was imprisoned and a trusted guard set over him, with every precaution taken to insure absolute secrecy. Should Martian spies, still thick in every Terrestrial community, despite the ceaseless war waged upon them, find out the facts of the man's capture, the plans of the Terrestrial high command might go for naught.
Commander Raws mentioned the affair once only. That was when he called Neil and his two friends into his quarters; and first making sure that nobody could hear them, spoke as follows:
"I do not condone your absence without leave although it may have chanced to bring fortune to our cause. Yet the high command feels that there is some reward due you."
He paused and studied the three young faces.
"That reward will be the knowledge of what your part will be in further action against this Martian force," he continued. "Well, I have asked for and received permission for my squadron to be included in the raiding group that is going to tackle them. No, ask no questions. Dismiss!"
Thereafter nothing more was said and no further hint of the nature of the plan of campaign was forthcoming. Only here and there, all over Earth's surface, isolated flights and squadrons of war-craft were given extra-duty training, were led in longer and more intricate maneuvers than their fellows; were ordered to install fighting equipment on their ships and to practice its use.
The number of Martians inside the round hull of the asteroid, according to the prisoner, was about six hundred thousand. The asteroid would have several thousand swift, light raiding ships, all fully armed and, in addition, the sham world would assuredly be defended and fortified to a high degree. Undoubtedly it was well guarded and observers with television and astronomical equipment would keep close watch on Earth as they approached. A fleet of space-ships could hardly steal upon that mile-size ball through coverless space—surprise would be out of the question. And chances seemed hardly better that the battle could be won by sheer force of arms.
