responsible for sending the fabulous spaceman into sure destruction. Against the ten known cruisers and the suspected superdreadnaught that were searching that quadrant for the illusive Station 9, the strength of Flotilla Blue Three was sadly inadequate. If the message had arrived earlier, a dreadnaught or at least a couple of cruisers could have been despatched with Hartnett's force. But the impossibility of a rendezvous in space made it strictly the Commodore's baby now. Besides, Terra had no ships to spare. Hartnett would have to rescue the three technicians at the Station and destroy the Isotope X-R with no help. The Cats didn't know what X-R was, but they wanted to find out awfully badly if their concentration of strength in the Uranus quadrant was any indication. And it wouldn't be very long before they found that the mysterious Station 9 was on Oberon, either. With more than eleven ships prowling around, they wouldn't miss such an obvious bet for very much longer. All Hartnett had to do now was sneak through their screen, land a ship on Oberon, take the technicians off, destroy the X-R, and get away again without being seen because the Artemis couldn't fight! Long groaned. That's all! Oh, why, he wondered, wouldn't Terrans learn? An ancient leader of Terra's nationalist era had said it perfectly for them. Speak softly, he had said, but carry a big stick! Why wouldn't they listen? He shook his head and left the Control Tower wearily. "What's eating him?" asked the relief. "He's just sent Blue Three into the Uranus quadrant," replied Reilly. The relief gave a low whistle and turned to look out over the earthlit moonscape. "Too bad." Hartnett caught the Commander's eye as he worked at the control board. "Sorry to crowd you like this, Mr. Scott," he said. "It's nothing at all, sir. It's a pleasure to have you aboard." Even as he said it, Scott realized how stupid it must sound. Of course it crowded him to have Hartnett aboard and it annoyed him being the second ranking officer on his own ship. Commodore Hartnett smiled at the Commander's words. There was hardly anything else he could say, poor devil. Rank has its privileges, he thought. But he said: "Glad you feel that way," and
