A chance swerve of the Hawker sprayed another line of pockmarks across the fuselage; and Simon drew back on the stick and went over in a sudden loop. Renway shot past under his tail and began to pull round in a belated vertical bank. The Saint put a curve in the fall of his loop and went to meet him. They raced head-on for a collision. Simon held his course till the last split second, lifted his nose slightly for a hint, and zoomed over the Hawker's prop on the upturn of a switchback that carried him clear of death by shaved inches.
He looked down on the swing-over of the stalling turn that ended his zoom, and saw Renway's ship sloping down, wobbling erratically. And his fine-drawn hell-for-leather smile opened out wickedly as he opened out the throttle and went down on the Hawker again in a shrieking power dive.
Down… down… The engine howling and the wires moaning shriller and shriller as the air-speed indicator climbed over three hundred and twenty miles an hour. His whole body tensed and waiting fearfully for the first vibration, the first shiver of the wing tips, that would spell the break-up of the machine. The Tiger Moth wasn't built for that sort of work. It was the latest, strongest, fastest thing of its kind in the air; but it wasn't designed for fighting aerobatics. He saw the Hawker dodging in hesitant clumsy efforts to escape; saw Renway's white goggled face staring back over the empennage, leaping up towards him at incredible speed. He set his teeth and pulled back the stick… Now! The Moth seemed to squat down in the air, momentarily blinding him as the frightful centrifugal force sucked the blood down from his head; but the wings held. He peered over the side and saw the Hawker diving again, veering wildly in the trembling control of its pilot.
Simon looped off the top of his zoom and went down again.
That was the only thing he could do, the only hope he had of beating the Hawker's guns. Dive and zoom, loop and dive again. Wipe the Moth's undercarriage across the Hawker's upper wing every time. Split-arch and dive again. Ride the Hawker down by sheer reckless flying. Wing-over and dive again, wires screaming and engine thundering. Smash down on Renway from every angle of the sky, pitting nerve against nerve, judgment against judgment; make him duck and push the stick forward a little more, every time, with the wheels practically rolling over his head with every hairbreadth miss. Beat him down five hundred feet, a thousand, fifteen hundred. Loop and dive again…
The Saint flew as he had never flown before. He did things that couldn't be done, took chances that could never come off, tore his machine through the air under strains that no ship of its class could possibly survive — and kept on flying. If Renway had been able to fly half as well, it couldn't have gone on.
But Renway couldn't fly half as well. For minutes at a time, his guns never had a target within forty-five degrees of them; and when he brought them round, the target had gone. And each time, a little more of his nerve went with it. He was losing height faster and faster, losing it foot by foot to that nerveless demon of the sky who seemed to have made up his mind to lock their machines together and send them crashing to earth in a single shroud of flame… The Saint smiled with merciless blue eyes like chips of frozen sea water; and dived again… He was going to win. He knew it. He could see the Hawker wobbling more wildly at every moment, plunging more panickily downwards at every effort to escape, sprawling more clumsily on every amateurish manoeuvre. He saw Renway's white face looking round again, saw a gloved fist impotently shaken at him, saw the mouth open and heard in his imagination the scream of fury that was ripped to fragments in the wind; and he laughed. He could divine what was in Renway's mind — divine the trembling twitching fear that was shuddering through his flabby limbs, the clammy sweat that must have been breaking out on the soft body — and he laughed through a mask of merciless bronze and swept the Moth screeching down again to whisk its wheels six inches over Renway's helmet. Renway, the snivelling jelly who had called himself the Saint!
Then, for the first time in a long while, he looked down to see what else was happening, and saw that the dogfight had carried them about a mile out over the sea, and the transport plane was just passing over the cliffs.
Renway must have seen it, too. Suddenly, in a frantic vertical bank which almost went into a power spin, he turned and dived on it, his guns rattling.
Simon pushed the stick into the dash, flung the throttle wide, and went down like a plummet.
The sobbing growl of the motor wailed up to an eldritch shriek as the ship slashed through the air. Down and down; with a wind greater than anything in nature slapping his face and plucking at his goggles, while the transport plane curled away in a startled bank and Renway twisted after it. Down and down, in the maddest plunge of that fantastic combat. Fingers cool and steady on the stick, feet as gentle on the rudder bar as the hands of a horseman on the reins, every coordinated nerve and muscle holding the ship together like a living creature. Bleak eyes following every movement of his quarry. Lips parted and frozen in- a deadly smile. Down and down, till he saw the bulk of the Imperial Airways monoplane leap upwards past the tail of his eye, and realized that Renway had shot down past his mark without scoring a hit. Downwards still, while Renway flattened out in a slow turn and began to climb again.
Finish it now — before Renway got in another burst which might be lucky enough to score.
Down… But there wasn't a civil aeroplane built which could squat down out of a dive like that without leaving its wings behind. It would have to be fairly gentle — and that would be bad enough. As coolly as if he had been driving a car at twenty miles an hour, the Saint judged his margin and felt the resistance on the stick. For one absurd instant he realized that Renway's cockpit was coming stone-cold into the place where the sights would have been if the Moth had been armed…
Crash!
The Moth shuddered under him in an impact like the explosion of a big gun. The painted map whirled across his vision while he fought to get the ship under control. He glanced out to right and left — both wings were still there, apparently intact. The nose of the machine began to lift again, steadily, across the flat blue water and the patchwork carpet, until at last it reached the horizon.
Simon looked down.
The Hawker was going down, five hundred feet below him, in a slow helpless spin. Its tail section was shattered as if a giant club had hit it, and tangled up with it were some splintered spars which looked as if they had belonged to his own landing gear. He had glimpses of Renway struggling wildly in the cockpit, wrestling with the useless controls, and felt a momentary twinge of pity which did not show in his face. After all, the man must have been mad… And even if he had killed and tried to kill, he was not going to the most pleasant of all deaths.
Then Simon remembered the bombs which the Hawker was supposed to carry, and realized that the end might be quick.
He watched the Hawker with a stony fascination. If it fell in the sea, the bombs might not go off. But it was very near the cliffs, bobbing and fluttering like a broken grey leaf… For several seconds he thought it would miss the land.
And then, in one of those queer freaks of aerodynamics which every airman knows, it steadied up. For an instant of time it seemed to hang poised in the air. And then, with the straight clean swoop of a paper dart it dived into the very rim of the surf which was creaming along the foot of the white cliffs. There was a split second of horrible suspense; and then the wreckage seemed to lift open under the thrust of a great tongue of orange-violent flame…
