"Yes, I'm sure I'd be able to spot him again, too," Dawson murmured. Then, with a grim note in his voice, "And that Japrat, too, even though I did only see him at a distance."

The vice-admiral was again scowling down at his clenched fist grinding into the palm of his other hand, and he acted as though he had not heard either of them speak. Dawson waited a few moments, and then asked a question.

"What about the service records of the fighter pilots aboard all three carriers, sir?" he said.

The base commandant raised his head and looked at him sharply.

"What do you mean?" he demanded. "And why just the fighter pilots?"

"From the way they talked, sir," Dawson replied quickly, "I felt certain that he was a fighter pilot. I mean, he plans to take off, when the opportunity presents itself, and fly direct to Truk. Well, sir, if he were a torpedo plane or dive bomber or scout bomber pilot, he would have somebody along with him. Gunner, or radio man, or both, I mean, sir. But neither of them made any mention of anybody else. So I feel certain that he's a fighter pilot."

"Yes, I guess you're right there, Dawson," the senior officer said with a nod. "But how would service records help us to find our man?"

"Well, sir," Dave said after a moment of frowning hesitation, "he is obviously German. He probably has a German-sounding name. His record sheet would tell about his parents. Where they were born, and so forth. He may even be a naturalized American, sir. Of course, it's just a long shot chance, but checking the service records of all the fighter pilots in that carrier force might turn up something that was suspicious-looking."

"It might, but I'm afraid it would be even harder than the needle in the haystack stunt," the base commandant said with a shrug. "Both the Army and the Navy have men of German birth, and parents. And it would take time. All that sort of thing is on file at the Navy Department in Washington. We haven't records that complete here. Of course, though, I'll get the wheels moving on it, at once. I'd be a fool to leave any stone untouched, and unturned. If that devil once ..."

The senior officer cut himself off with a groan, and his dismay and worry showed plainly on his face.
