"We'll manage, somehow," Lanyard affirmed stoutly.
The aviator smiled curiously. "To begin with," he advanced, "I daresay we might as well get rid of these awkward costumes. They'll hamper walking — rather."
In spite of his fatigue Lanyard was so struck by the circumstances that he couldn't help remarking it as he tore off his wind-veil.
"Your English is remarkably good, Captain Vauquelin," he observed.
The other laughed shortly.
"Why not?" said he, removing his mask.
Lanyard looked up into his face, stared, and fell back a pace.
"Wertheimer!" he gasped.

DAYBREAK
The Englishman smiled cheerfully in response to Lanyard's cry of astonishment.
"In effect," he observed, stripping off his gauntlets, "you're right, Mr. Lanyard. 'Wertheimer' isn't my name, but it is so closely identified with my — ah — insinuative personality as to warrant the misapprehension. I shan't demand an apology so long as you permit me to preserve an incognito which may yet prove somewhat useful."
"Incognito!" Lanyard stammered, utterly discountenanced. "Useful!"
"You have my meaning exactly; although my work in Paris is now ended, there's no saying when it may not be convenient to be able to go back without establishing a new identity."
Before Lanyard replied to this the look of wonder in his eyes had yielded to one of understanding.
"Scotland Yard, eh?" he queried curtly.
Wertheimer bowed. "Special agent," he added.
"I might have guessed, if I'd had the wit of a goose!" Lanyard affirmed bitterly. "But I must admit…"
"Yes," the Englishman assented pleasantly; "I did pull your leg — didn't I? But not more than our other friends. Of course, it's taken some time: I had to establish myself firmly as a shining light of the swell mob over here before De Morbihan would take me to his hospitable bosom."
"I presume I'm to consider myself under arrest?"
With a laugh, the Englishman shook his head vigorously.
"No, thank you!" he declared. "I've had too convincing proof of your distaste for interference in your affairs. You fight too sincerely, Mr. Lanyard — and I'm a tired sleuth this very morning as ever was! I would need a week's rest to fit me for the job of taking you into custody — a week and some able-bodied assistance!… But," he amended with graver countenance, "I will say this: if you're in England a week hence, I'll be tempted to undertake the job on general principles. I don't in the least question the sincerity of your intention to behave yourself hereafter; but as a servant of the King, it's my duty to advise you that England would prefer you to start life anew — as they say — in another country. Several steamers sail for the States before the end of the week: further details I leave entirely to your discretion. But go you must," he concluded firmly.
"I understand…" said Lanyard; and would have said more, but couldn't. There was something suspiciously like a mist before his eyes.
Avoiding the faces of his sweetheart and the Englishman, he turned aside, put forth a hand blindly to a wing of the biplane to steady himself, and stood with head bowed and limbs trembling.
Moving quietly to his side, the girl took his other hand and held it tight….
Presently Lanyard shook himself impatiently and lifted his head again.
"Sorry," he said, apologetic — "but your generosity — when I looked for nothing better than arrest — was a bit too much for my nerves!"
"Nonsense!" the Englishman commented with brusque good-humour. "We're all upset. A drop of brandy will do us no end of good."
Unbuttoning his leather surtout, he produced a flask from an inner pocket, filled its metal cup, and offered it to the girl.
"You first, if you please, Miss Shannon. No — I insist. You positively need it."
She allowed herself to be persuaded, drank, coughed, gasped, and returned the cup, which Wertheimer promptly refilled and passed to Lanyard.
The raw spirits stung like fire, but proved an instant aid to the badly jangled nerves of the adventurer. In another moment he was much more himself.
Drinking in turn, Wertheimer put away the flask. "That's better!" he commented. "Now I'll be able to cut along with this blessed machine without fretting over the fate of Ekstrom. But till now I haven't been able to forget —— "
He paused and drew a hand across his eyes.
"It was, then, Ekstrom — you think?" Lanyard demanded.
"Unquestionably! De Morbihan had learned — I know — of your bargain with Ducroy; and I know, too, that he and Ekstrom spent each morning in the hangars at St. Germain, after your sensational evasion. It never entered my head, of course, that they had any such insane scheme brewing as that — else I would never have so giddily arranged with Ducroy — through the Sûreté, you understand — to take Vauquelin's place…. Besides, who else could it have been? Not De Morbihan, for he's crippled for life, thanks to that affair in the Bois; not Popinot, who was on his way to the Santé, last I saw of him; and never Bannon — he was dead before I left Paris for Port Aviation."
"Dead!"
"Oh, quite!" the Englishman affirmed nonchalantly, "When we arrested him at three this morning — charged with complicity in the murder of Roddy — he flew into a passion that brought on a fatal haemorrhage. He died within ten minutes."
There was a little silence….
"I may tell you, Mr. Lanyard," the Englishman resumed, looking up from the motor, to which he was paying attentions with monkey-wrench and oil-can, "that you were quite off your bat when you ridiculed the idea of the 'International Underworld Unlimited.' Of course, if you hadn't laughed, I shouldn't feel quite as much respect for you as I do; in fact, the chances are you'd be in handcuffs or in a cell of the Santé, this very minute…. But, absurd as it sounded — and was — the 'Underworld' project was a pet hobby of Bannon's — who'd been the brains of a gang of criminals in New York for many years. He was a bit touched on the subject: a monomaniac, if you ask me. And his enthusiasm won De Morbihan and Popinot over … and me! He took a wonderful fancy to me, Bannon did; I really was appointed first-lieutenant in Greggs' stead…. So you first won my sympathy by laughing at my offer," said Wertheimer, restoring the oil-can to its place in the tool-kit; "wherein you were very wise…. In fact, my personal feeling for you is one of growing esteem, if you'll permit me to say so. You've most of the makings of a man. Will you shake hands — with a copper's nark?"
He gave Lanyard's hand a firm and friendly grasp, and turned to the girl.
"Good-bye, Miss Shannon. I'm truly grateful for the assistance you gave us. Without you, we'd have been sadly handicapped. I understand you have sent in your resignation? It's too bad: the Service will feel the loss of you. But I think you were right to leave us, the circumstances considered…. And now it's good-bye and good luck! I hope you may be happy…. I'm sure you can't go far without coming across a highroad or a village; but — for reasons not unconnected with my profession — I prefer to remain in ignorance of the way you go."
Releasing her hand, he stepped back, saluted the lovers with a smile and gay gesture, and clambered briskly to the pilot's seat of the biplane.
When firmly established, he turned the switch of the starting mechanism.
The heavy, distinctive hum of the great motor filled that isolated hollow in the Downs like the purring of a dynamo.
With a final wave of his
