Seven-fifteen....
Lance pressed the starting button. His four motors choked, sputtered, then burst into a sweet, full-throated roar. He glanced over at Praed's plane, spun the small helicopter props over and pushed down the accelerator. The plane quivered, stuck its snout up and leaped like an arrow into the clean, darkening air. Lance gunned it to ten thousand feet, Praed following him neatly. Praed was a good pilot, no doubt about that. The two fighting machines hung for a second side by side; Lance eased off his helicopters and streaked away into the gloom at a breath-taking five hundred.
"I hope," muttered Colonel Douglas as the two tiny scouts sped from sight, "that everything goes smoothly. They're the men to do it, anyway. No better pilots in the whole service."
"Wot abaht that there Captain Hay, sir?" put in Wells, the mechanic, standing nearby. Colonel Douglas smiled.
"Oh, of course!" he amended. "I'd forgotten Hay!"
Once more they were anticipated! Lance, at thirty thousand feet--the Rahl-Diesels, with their perfected superchargers, were easily capable of a ceiling of sixty--had hovered above the position of Hill 333, pulled on his gas-mask and said through the microphone to Praed:
"Power dive to three thousand feet. Release your flares and take in all you can before they send up planes. We'll take 'em by surprise, but there's bound to be a fight. Got it?"
The steady reply came back: "Okay."
Whereat Lance set his teeth in his customary fighting grin, jockied up his ammunition belts, glanced at the flare-parachutes folded alongside the cabin and plunged the scout in a dive that tipped six hundred and fifty miles and threatened to crack the speed dial.
* * * * *
But surprise? Nothing doing! Like angry hornets five Slav planes pounced on them at ten thousand feet. They'd been waiting there! Lance cursed savagely. He flung off his flares, Immelmanned up, and in less than two seconds had sent one Slav shrieking to the ground in flames. For the moment forgetting Praed, Lance followed after his flares, three Slavs attempting to sight their guns on the twisting, writhing, corkscrewing body of his Goshawk. He knew there were disintegrating flame-throwers below, but gambled on their not shooting because of the enemy scouts diving with him.
Flattening out at perhaps a thousand feet, Lance threw a rapid stare at the bulk of Hill 333. He drew his breath in sharply.
Lit dazzlingly by the bleaching white of the slow-floating flares, huge rows of the dreaded Slav tanks were clustered all around the hill!
As he looked, ten more Slav planes came soaring up from the ground. This was too hot! The thought of Praed stabbed through Lance's whirling brain; he pulled the scout around, doubled over the three closing in on his tail, and belched lead for an instant at one he'd caught off guard. It collapsed like a punctured paper bag. Lance grinned and bounded to the upper regions. The two other Slavs let the crazy Yank go for the instant, joining forces with the ten brothers coming to help them out.
Lance, again at ten thousand, looked for Praed. Far above, he glimpsed two planes, circling and diving. Praed seemed to be fighting, at any rate! As he watched, the two scouts catapulted still higher; became tiny, almost imperceptible dots, visible only in the reflected light of the flares. Then Lance felt a shaft of ice along his spine.
The two planes had practically hugged each other for a second. Then one of them fell away, somersaulted, tumbled down wildly--out of control.
It passed Lance like a falling rock.
And it was Praed's scout!
"My God!" muttered Lance. "He's been shot down!"
* * * * *
The next moment the twelve Slavs were on him like a hurricane. Motors roaring, Lance stood them off--flinging a burst of lead here, dropping out of range here, looping, catapulting, zooming--fazing them with every trick he knew. A dozen times he sensed the zinging wrath of storms of bullets, a dozen times he escaped death by the breadth of a hair. Not for nothing was he called one of the best pilots in the service, second only to Hay.
He bagged another of the Slavs, and began to think of getting away. Praed had proved himself, but had been killed in doing so. He's got the dope on Hill 333. Now for the getaway.
As he whirled, another Slav plane--the one that had got Praed--dove down from above. And, in the last second of the ghostly light of the flares, Lance's bewildered eyes saw the face of the man inside it.
That face was Praed's!
Praed, inside an enemy scout! Praed firing at him! Praed, not dead!
Lance was dumbfounded. He almost died, just then, for he felt his senses stagger, and relaxed his maneuvering. Praed! What--how--He couldn't begin to reckon it out.
If the flares hadn't died at that instant, Lance must have been shot down. Luckily, they expired; pitch darkness washed over everything. The lights on the Slav planes switched on, their prying beams fingering the sky for Lance's plane. But Lance was somewhat himself again. He jammed the accelerator down, dove headlong, flattened out and streaked for home. The speed of the Goshawk snatched him faithfully from the jaws of the Slavs. He left then milling behind. Left Praed with them!
* * * * *
Colonel Douglas was waiting for him. Lance's face must have been a study, for the elder man laughed shortly. "You need a drink!" he decided, and poured out a stiff tot of rum. Lance downed it with a nervous gulp and sprawled in a chair, the glass held weakly in quivering fingers.
Dead silence brooded over the whole base. Even the muttering guns were still. One green-shaded light threw the maps on Douglas' desk into glaring prominence; besides that, there was no illumination anywhere in the 'drome. Lance knew he had a thumping headache and that his eyes were lumps of pain. The glass fell from his hand and crashed on the floor. It seemed to stir the young captain, for at last he looked up and met the colonel's inquiring gaze.
"Well?" The colonel was terse.
"I saw Praed shot down," Lance mumbled, as if to himself, "and then I saw him--"
"Wait!" Douglas strode rapidly to the door which led to the other rooms of the building. After glancing to right and left, with an explanatory "Walls sometimes have ears, you know!" he locked the door carefully again, came back, and said:
"Talk in a whisper! How about Hill 333?"
"Tanks massed there," Lance said slowly. "Yeh, I saw that, all right. They must be intending an attack on that sector. But--but--Praed--"
"What happened?"
Lance told him of the scrap, how Praed's plane had apparently rubbed wings with a Slav and then tumbled down, out of control. He concluded: "I figured that Praed was all right, that he'd proved himself, that he wasn't a spy, as we'd thought. But the next moment I saw him in the Slav plane that had bagged his!"
His wondering eyes sought the colonel's lean face. Lance expected to see it express amazement, incredulity. It didn't, though. He laughed!
* * * * *
While Lance gaped, the older man went to the delicate machinery of the radiophone in one corner of the trim office. He clasped the earphones over his head, and spoke into the mike: "Headquarters, Air Force, Washington, Douglas, Base 5, speaking."
A tense moment passed while his radio call was put through. Presently a green light flashed on the board. Douglas said swiftly: "Headquarters? Base 5, Colonel Douglas. Tanks massed around Hill 333; enemy evidently contemplates full attack on corresponding sector of our line. They know a scout of ours observed it, however; perhaps that will induce them to change their plans. This next is extremely important: The first step of the Torpedo Plan has been successful!"
For awhile he listened intently, replying with short-clipped affirmatives. Then he hung the headphones up and turned to the bewildered Lance. Colonel Douglas laughed again and rubbed his hands exultantly.
"What the hell--" Lance began. The other pulled out a drawer of his desk and took from it a small placard.
"Do you recognize the photo?" he asked smilingly.
Lance looked at it. It was the picture of a man in the uniform of a captain of t
he Air Force, a row of battle ribbons on his straight, khaki-clad chest. But it was the figure's face that Lance stared at.
"Sure," he said finally. "It's a picture of Praed. But what--"
"Not Praed," corrected the colonel. "Not Praed. Captain Basil Hay."
PART III
"Good Lord!" Lance exclaimed without knowing he did so. Praed--Hay! The same man! Then that was the secret; that explained things! Hay, the hero of the force!
"You're entitled to a few explanations," Douglas said. "I'll give you the core of the whole scheme. There's no need to tell you that it must be guarded with your life." He drew his chair closer to Lance's.
"Yes, it's true. The man you knew as Praed in reality is Captain Hay. You see, Lance, headquarters was taking no chances with what I just called the Torpedo Plan. Every move had to be conducted with the utmost secrecy. Had to be! For the Torpedo Plan is, in some ways, America's last hope.
"Our base, No. 5, was chosen as the center of activity, the base from which the steps paving the way for the plan would be taken. The two best pilots in the service were needed. You and Hay were chosen.
"It was decided it would be best to mask Hay's real identity. So, officially, he was sent to the hospital; in reality he came here, under the name of Praed. Why? Because there's a spy somewhere--we don't seem to be able to track him; he's infernally clever--and if the famous Captain Hay was switched to Base 5, putting the two best pilots in the service together, that spy'd know something was in the air. Understand?"
Lance nodded dumbly. A great light was beginning to shower him.
"To more completely mask our true purpose," the colonel continued, "Hay was instructed to make it appear as if he were a spy. And it was a damned hard job! The real spy, whoever he is, and wherever he is, would thus be additionally fooled; for all he'd know, the Slavs might have sent another over to back him up. That's why Hay never shot down an enemy plane. Says something about his skill as a pilot, doesn't it? Never able to defend himself, save by maneuvering. He's a great flyer!"
Lance could only nod dumbly again.
"After a couple of weeks at this base," Douglas went on, "Hay was to cross the lines one night with you accompanying him. You, unintentionally, would thus occupy the enemy planes while Hay attended to the real business of the evening. And you did splendidly!"
"The real business?" Lance questioned. "What the devil was that? I thought the real business was to get the dope on Hill 333."
"So it was--partially. But also to take the first step of the Torpedo Plan, which was for Hay to switch over to a Slav plane."
"What?"
* * * * *
The colonel repeated his statement, somewhat dryly. Lance's square jaw dropped abruptly. "But--but--" he exclaimed, "how the devil could he do that?"
Colonel Douglas grinned.
"By a very neat contraption from the brain of one of our most valuable scientists," he explained. "Hay's scout was specially fitted up before you left; while you were sleeping, in fact. Two experts from Washington arrived with that batch of new recruits this afternoon. A tiny sliding door was cut in the fuselage of the scout and a sort of folding ladder put inside. It was motivated by some rather complex spring-work; but the really ingenious thing about it was the powerful electro-magnet at its base.
"It's rather over my head," he smiled. "I'm a plain fighting man, and sometimes it seems that scientists and not fighting men are going to win this war.... But, at any rate, it worked like this:
"Hay lures, or maneuvers, a Slav plane away from its fellows, and while you're down below entertaining the others, flies wing to wing with it. He touches the spring of his ladder and it shoots out, powerfully magnetized, and clamps onto the steel fuselage of the Slav. The automatic control keeps Hay's scout steady, and the ladder is so highly attractive that the Slav simply can't get away. Hay crosses the gulf, taking with him the cord which controls the electro-magnet. He forces his way into the Slav, shoots down its pilot, releases the pull of the magnet, and--there you are! Our best pilot in possession of a Slav plane, and clad in a Slav officer's uniform! Do you get the idea now?"
Lance strove for appropriate words. "Gee!" he spluttered. "It's--it's wonderful! And to think I tried to start a fight with Hay! I wish I'd known before. But I suppose," he added, "it was best to let not even me in on it, to keep it absolutely secret."
"Exactly!"
"And now what's Hay's mission?" Lance asked eagerly.
* * * * *
Colonel Douglas' face became sober. "A damnably dangerous one, and a mighty desperate one. As I said, the Torpedo Plan, which Hay is striving to carry out, seems to be America's last chance. We're holding the United Slavs, but only just. We simply can't break their line or make any headway against them; and when they do unleash their big push, there's nothing to stop them! So we're gambling everything on this slim hope.
"American science," he continued, "has perfected a weapon which is called the 'flying torpedo.' It's a ghastly thing, too. Damn it, I actually feel sorry for the poor devils it bursts on! It's a sort of riposte to their disintegrating flame.
"Picture a huge tanklike affair of steel, one hundred feet long. Picture a few dozen of them! Picture them crammed to overflowing with tons of glyco-scarzite, the most destructive explosive the mind of man has yet conceived. An explosive that can't be hurled in a shell and can't be dropped in a bomb from a plane. A pound or so of it, man, lays waste a square mile of anything! Even our scientists are a bit afraid of it. They've been trying to think up a way of unleashing it at the Slavs. And these flying torpedoes seem to be the answer.
"The torpedoes are purely mechanical. Therefore, they can soar to any height whatsoever. Twenty, thirty, even forty miles. All right. Now, picture a dozen or so of these torpedoes soaring over the most important Slav bases and headquarters, thirty miles above the earth, at night, of course, and absolutely invisible to the most powerful search-rays. They fly without the slightest sounds. Get that? Well, when this squadron of awful death arrives at the exact point over the place to be demolished, the motive force switches off and down they crash. Imagine what will happen when they collide with the ground!" Douglas, with Lance's tense eyes on him, struck a clenched fist into an open palm.
"Tons of glyco-scarzite, Lance! Unleashed, without warning, from miles above! Thirty of these torpedoes, each a hundred feet long, dropping down on the very heart of the Slav invasion! Killing, blowing to bits, rather, every living thing, every fortification, every tree, every tank, every gun, every flame thrower, every plane in a radius of hundreds of miles!"
"God!" came from Lance's numb lips. "God!"
"But"--and the colonel held up a straight forefinger--"these torpedoes must be guided from the place they raid!"
Into the silence Lance whispered: "And that--that is Hay's job?"
"That," Douglas confirmed levelly, "is Hay's job--and yours."
* * * * *
Their eyes met; held. And then Lance's clean young face smiled.
"Thank God, sir," he cried, "that I'm to help strike the blow that'll free our country!"
Colonel Douglas answered his smile with a smile. "Lance," he said, "it's because Washington has put this job into Hay's and your hands that I know--I know--it will succeed."
"It will!"
Douglas lowered his voice again. "This is why those flying torpedoes must be guided from the Slav's innermost base.
"In the first place, they fly too high for an accompanying plane to guide them. In the second, the power that releases them to hurtle downwards must come from the enemy base itself, to permit of no possible error. This must not fail!"
"But," put in Lance, "how do the torpedoes fly? What motivates them?"
"A closely guarded secret, of course," he was told. "I merely possess a slight comprehension of it. I know that it is an adaptation of that discovery of Professor Singe, two years ago--cosmic attraction. Eventually, perhaps, it will permit interplanetary travel. This use of it is simply the beginning. But
it is to America's everlasting glory that a scientist of hers developed it.
"You know how a sliver of wood is propelled by the ripples of a pond? Vibrations of the water, really. Well, evidently there are somewhat similar vibrations in the ether, cosmic force. Each one of these flying torpedoes contains a highly expensive, intricate mechanism which transforms this invisible vibration-power into material propulsion. The mechanism is adjusted to propel the torpedo at such an altitude in such a direction. We possess no means of setting the machines to stop at a certain place and so tumble earthwards. That's where you and Hay come in.
