"Next April!" figured Neil quickly. "And then?"

"And then the little world will empty itself. It can bring forth two thousand heavily-armed ships, manned by six hundred thousand picked men. The space armies of Earth with their ships and weapons will be mighty and many, but unwary. Those two thousand Martian raiders will sell themselves at the highest cost, crippling and destroying Earth's defenses and cities to the utmost of their power. If they are lucky, you and your comrades will be prostrated, so that, months later, the expeditionary force from Mars can capture the planet without serious opposition."

The Martian bowed slightly, as if he were concluding a public address.

"I wonder if he's lying," said Bull Mike.

"Not at all, gentlemen," said the Martian. "Do you give me credit for inventing such a wonderful tale?"

"Let's get back to Earth," suggested Neil.

"Right," seconded Sukune. "Back there we'll turn ourselves in for being absent without leave, but they'll forget about us when they check this lad's veracity under the truth-ray."

The three agreed. First they bound their prisoner hand and foot. Bull Mike was told off to mount guard over him and Sukune returned to the controls. Putting on the Martian's space-suit, Neil hopped out and across the abyss to the other ship where it still clung by its automatic grapple. Transferring some new fuel to its tanks, he sent it speeding along in the wake of Sukune's craft.

In the stratosphere above St. Louis a patrol sighted and hailed them. The Martian craft was instantly boarded and seized, and the commander of the patrol bombarded the occupants of the two vessels with sharp, suspicious questions. At last he listened to the pleadings of the young Terrestrials and took them and their prisoner direct to their home rocketport, where Commander Scholom Raws, the officer of the space-scout squadron to which they belonged, was called to hear their story.

His first sharp accusation of truancy was stilled as they poured out their strange tale. When they had finished he ordered them to form a guard for the Martian and led the way at once to staff headquarters of the Intelligence Department many levels below.
