“That’s swell. Thanks,” he exclaimed. “I just wanted to see if you were real.” He was to know much more about that a few moments later. “Listen! I think I hear the roar of a heavy plane!” Mary exclaimed suddenly. Ted listened. The drone of his own motor was in his ears. He heard nothing else. “Guess you imagined that,” he said. “Strange things happen to you in the sky. There are mirages of sound as well as of sight.” She made no reply. The steady drumming was still in her ears. She was tired. It had been a long, exciting day. She wondered vaguely what they would do with her when she got aboard the _Black Bee_, if she ever did. She hoped there was a tiny cabin where she could sleep forever and ever. Thinking of this, she nearly fell asleep when Ted exclaimed: “Look at that! The light of the moon blinked out and there’s not a cloud in the sky!” “But it’s on now!” she laughed. “Yes, it came right back, but—” “There!” she exclaimed. “It’s off again! No! Now it’s on—” Ted did not answer. He was beginning to think he knew what was up. He hoped the moon would blink again. And he was not disappointed. “Look at the moon! Quick!” He was all excited. “It’s out!” she protested. “Look closer! There’s a Jap snooper between us and the moon. Now it’s below the moon! Once you get it spotted, you can see it anywhere.” “What’s a Jap snooper?” she asked. “A big four-motored flying boat looking for a U. S. convoy.” “Oh!” she breathed. “We have to get that one, don’t we?” “I’ll say we do! Wonder if Jack’s radio works?” Then, “No matter. Don’t dare call him. We’ll get after that snooper alone.” The girl’s hair seemed to rise and stand up like a fuzzy-wuzzy’s, but she was game. “Get them!” she hissed. She was thinking of the horrors of Corregidor and Bataan. Giving his ship the gun, keeping an eye on the giant’s shadow, Ted began to climb. The big ship was slow. They gained rapidly. At just the right moment Ted came racing down upon the snooper. They were almost upon it when Ted let out a burst of murderous fire. He shot past the big ship, swung back, felt his way until the snooper was again between him and the moon, then went straight at her. Again at very close range he pressed the firing button. But what was this? The gun fired a few shots, then jammed. “Bum outfit—not my ship nor my gun,” he groaned. All of a sudden, to his astonishment, he caught the _rat—tat—tat_ of a gun behind him. It was Mary. They were passing beneath the enemy. She was firing the rear gun, straight up. “Good girl!” he exclaimed. “Give it to them!” Flashes of fire came from the enemy, but the shots went wild. “We’ll swing about and meet them almost head on,” he said in a steady voice. “I’ll dip down just in time and you give them all you’ve got.” “I—I’ll do my darndest.” She braced herself for the ordeal. They very nearly missed going low enough. It seemed to Ted that they must have scraped the big boat’s keel, but Mary got in her good work.
