He saw the monoplane check abruptly in its strong onward surge — as if it had run, full-tilt, head-on, against an invisible obstacle — and for what seemed a round minute it hung so, veering and wobbling, nuzzling the wind. Then like a sounding whale it turned and dived headlong, propeller spinning like a top.
Down through the eighth of a mile of space it plunged plummet-like; then, perhaps caught in a flaw of wind, it turned sideways and began to revolve, at first slowly, but with increasing rapidity in its fatally swift descent.
Toward the beginning of its revolutions, something was thrown off, something small, dark and sprawling … like that glove which Lanyard had discarded. But this object dropped with a speed even greater than that of the Valkyr, in a brace of seconds had diminished to the proportions of a gnat, in another was engulfed in that vast sea of golden vapour.
Even so the monoplane itself, scarcely less precipitate, spun down through the abyss and plunged to oblivion in the fog-rack….
And Lanyard was still hanging against the chest-band, limp and spent and trying not to vomit, when, of a sudden and without any warning whatever, the stentorian chant of the motor ceased and was blotted up by that immense silence, by the terrible silence of those vast solitudes of the upper air, where never a sound is heard save the voices of the elements at war among themselves: a silence that rang with an accent as dreadful as the crack of Doom in the ears of those three suspended there, in the heart of that unimaginably pellucid and immaculate radiance, in the vast hollow of the heavens, midway between the deep blue of the eternal dome and the rose and golden welter of the fog — that fog which, cloaking earth and sea, hid as well every vestige of the tragedy they had wrought, every sign of the murder that they had done that they themselves might not be murdered and cast down to destruction.
And, its propeller no longer gripping the air, the aeroplane drifted on at ever-lessening speed, until it had no way whatever and rested without motion of any sort; as it might have been in the cup of some mighty and invisible hand, held up to that stark and merciless light, under the passionless eye of the Infinite, to await a Judgment….
Then, with a little shudder of hesitation, the planes dipped, inclined slightly earthwards, and began slowly and as if reluctantly to slip down the long and empty channels of the air.
At this, rousing, Lanyard became aware of his own voice yammering wildly at Vauquelin:
"Good God, man! Why did you do that?"
Vauquelin answered only with a pale grimace and a barely perceptible shrug.
Momentarily gathering momentum, the biplane sped downward with a resistless rush, with the speed of a great wind — a speed so great that when Lanyard again attempted speech, the breath was whipped from his lips and he could utter no sound.
Thus from that awful height, from the still heart of that immeasurable void, they swept down and ever down, in a long series of sickening swoops, broken only by negligible pauses. And though they approached it on a long slant, the floor of vapour rose to meet them like a mighty rushing wave: in a trice the biplane was hovering instantaneously before plunging on down into that cold, grey world of fog.
In that moment of hesitation, while still the adventurer gasped for breath and pawed at his streaming eyes with an aching hand, pierced through and through with cold, the fog showed itself as something less substantial than it had seemed; blurs of colour glowed through its folds of gauze, and with these the rounded summit of a brownish, knoll.
Then they plunged on, down out of the bleak, bright sunshine into cool twilight depths of clinging vapours; and the good green earth lifted its warm bosom to receive them.
Tilting its nose a trifle, fluttering as though undecided, the Parrott settled gracefully, with scarcely a Jar, upon a wide sweep of untilled land covered with short coarse grass.
For some time the three remained in their perches like petrified things, quite moveless and — with the possible exception of the aviator — hardly conscious.
But presently Lanyard became aware that he was regularly filling his lungs with air sweet, damp, wholesome, and by comparison warm, and that the blood was tingling painfully in his half-frozen hands and feet.
He sighed as one waking from a strange dream.
At the same time the aviator bestirred himself, and began a bit stiffly to climb down.
Feeling the earth beneath his feet, he took a step or two away from the machine, reeling and stumbling like a drunken man, then turned back.
"Come, my friend!" he urged Lanyard in a voice of strangely normal intonation — "look alive — if you're able — and lend me a hand with mademoiselle. I'm afraid she has fainted."
The girl was reclining inertly in the bands of webbing, her eyes closed, her lips ajar, her limbs slackened.
"Small blame to her!" Lanyard commented, fumbling clumsily with the chest-band. "That dive was enough to drive a body mad!"
"But I had to do it!" the aviator protested earnestly. "I dared not remain longer up there. I have never before been afraid in the air, but after that I was terribly afraid. I could feel myself going — taking leave of my senses — and I knew I must act if we were not to follow that other… God! what a death!"
He paused, shuddered, and drew the back of his hand across his eyes before continuing: "So I cut off the ignition and volplaned. Here — my hand. So-o! All right, eh?"
"Oh, I'm all right," Lanyard insisted confidently.
But his confidence was belied by a look of daze; for the earth was billowing and reeling round him as though bewitched; and before he knew what had happened he sat down hard and stared foolishly up at the aviator.
"Here!" said the latter courteously, his wind-mask hiding a smile — "my hand again, monsieur. You've endured more than you know. And now for mademoiselle."
But when they approached the girl, she surprised both by shivering, sitting up, and obviously pulling herself together.
"You feel better now, mademoiselle?" Vauquelin enquired, hastening to loosen her fastenings.
"I'm better — yes, thank you," she admitted in a small, broken voice — "but not yet quite myself."
She gave a hand to the aviator, the other to Lanyard, and as they helped her to the ground, Lanyard, warned by his experience, stood by with a ready arm.
She needed that support, and for a few minutes didn't seem even conscious of it. Then gently disengaging, she moved a foot or two away.
"Where are we — do you know?"
"On the South Downs, somewhere?" Lanyard suggested, consulting Vauquelin.
"That is probable," this last affirmed — "at all events, judging from the course I steered. Somewhere well in from the coast, at a venture; I don't hear the sea."
"Near Lewes, perhaps?"
"I have no reason to doubt that."
A constrained pause ensued. The girl looked from the aviator to Lanyard, then turned away from both and, trembling with fatigue and enforcing self-control by clenching her hands, stared aimlessly off into the mist.
Painfully, Lanyard set himself to consider their position.
The Parrott had come to rest in what seemed to be a wide, shallow, saucer-like depression, whose irregular bounds were cloaked in fog. In this space no living thing stirred save themselves; and the waste was crossed by not so much as a sheep track. In brief, they were lost. There might be a road running past the saucer ten yards from its brim in any quarter. There might not. Possibly there was a town or village immediately adjacent. Quite as possibly the Downs billowed away for desolate miles on either hand.
"Well — what do we do now?" the girl demanded suddenly, in a nervous voice, sharp and jarring.
"Oh, we'll find a way out of this somehow," Vauquelin asserted confidently. "England isn't big enough for anybody to remain
