Turning front again, Dave instantly picked up the other Devastator. And as he did so his heart leaped in his chest, and the blood began to pound through his veins. Smoke had stopped spewing from the engine exhaust. The plane had even stopped gliding. As a matter of fact, it was on even keel, and racing northward at full throttle not more than three or four thousand feet above the surface of the Pacific. That fact alone told Dave that after eight days and eight nights the gods of war had decided to give Freddy and him a real break. He knew, just as though a voice were shouting it in his ears, that the pilot of that Devastator thundering northward was in the pay of the Axis. And for some reason he felt equally sure that the Devastator's gunner was of the same breed. One thing that had puzzled him ever since Colonel Welsh had told of the double murder aboard the Aircraft Carrier Indian was whether one man or two had taken part in that gruesome affair. He had believed it was two for the reason that if there had been just one man, he would have been unable to kill both of the Indian's officers before one of them jumped him, or tried to, at least. And both had been shot right between the eyes. That fact, and other bits of reasoning, had led him to believe all along--though he had not spoken of it to Freddy Farmer--that they were after two Axis spies, not just one. And as he sent the Devastator rocketing downward and to the north, he felt more convinced than ever that such was the truth. "I could be wrong," he grunted softly as he kept his eyes fixed steadfastly on the other plane, "but I don't think so. Nope, I don't think so." "Dave!" Freddy's voice suddenly screamed in his ear again. "Look to starboard and ahead, on the horizon line. I think I spot smoke from the funnel of some surface ship. Can you see it, too?" Dave tore his gaze from the plane ahead and stared hard in the direction of the English youth's pointed finger. But all he could see was an endless expanse of blue water across which the shadows of coming night were beginning to steal. Where the water met the sky was little more than a blurred line to him. If there was smoke from a surface ship on that horizon line, he couldn't see it. However, many times had Freddy Farmer's eagle, X-ray eyes picked up things before he did. And so his heart began to dance about in his chest with wild excitement. And for the umpty-umpth millionth time he experienced that familiar eerie sensation at the back of his neck that seemed always to come to him when trouble and danger were in the offing. "You sure, Freddy?" he called out. "I can't see a darn thing. It's all just horizon line to me."
