"Plenty to look at," he repeated absently. "Plenty of Huns to gaze at. Huns? They were like ants below me, there. They swarmed under the mountain ledge as far as I could see—thousands of busy Boches—busy as ants. There were narrow-gauge railways, too, apparently running right into the mountain; and a deep broad cleft, deep as another valley, and all crawling with Huns.
"A tunnel? Nobody alive ever dreamed of such a gigantic tunnel, if it was one!… Well, I was up there three days. It was the first of August—thereabouts—and I'd been afield for weeks. And, of course, I'd heard nothing of war—never dreamed of it.
"If I had, perhaps what those thousands of Huns were doing along the mountain wall might have been plainer to me.
"As it was, I couldn't guess. There was no blasting—none that I could hear. But trains were running and some gigantic enterprise was being accomplished—some enterprise that apparently demanded speed and privacy—for not one civilian was to be seen, not one dwelling. But there were endless mazes of fortifications; and I saw guns being moved everywhere.
"Well, I was becoming hungry up on that fir-clad battlement. I didn't know how to get down into the valley. It began to look as though I'd have to turn back; and that seemed a rather awful prospect.
"Anyway, what happened, eventually, was this: I started east through the forest along that pathless tableland, and on the afternoon of the next day, tired out and almost starved, I stepped across the Swiss boundary line—a wide, rocky, cleared space crossing a mountain flank like a giant's road.
"No guards were visible anywhere, no sentry-boxes, but, as I stood hesitating in the middle of the frontier—and just why I hesitated I don't know—I saw half a dozen jagers of a German mounted regiment ride up on the German side of the boundary.
"For a second the idea occurred to me that they had ridden parallel to the ledge to intercept me; but the idea seemed absurd, granted even that they had seen me upon the ledge from below, which I never dreamed they had. So when they made me friendly gestures to come across the frontier I returned their cheery 'Gruss Gott!' and plodded thankfully across. … And their leader, leaning from his saddle to take my offered hand, suddenly struck me in the face, and at the same moment a trooper behind me hit me on the head with the butt of a pistol."
The girl's flying pencil faltered; she lifted her brown eyes, waiting.
"That's about all," he said—"as far as facts are concerned…. They treated me rather badly…. I faced their firing-squads half-a-dozen times. After that bluff wouldn't work they interned me as an English civilian at Holzminden…. They hid me when, at last, an inspection took place. No chance for me to communicate with our Ambassador or with any of the Commission."
He turned to her in his boyish, frank way: "But do you know, Miss Erith, it took me quite a while to analyse the affair and to figure out why they arrested me, lied about me, and treated me so hellishly.
"You see, I was kept in solitary confinement and never had a chance to speak to any of the other civilians interned there at Holzminden. There was no way of suspecting why all this was happening to me except by the attitude of the Huns themselves and their endless questions and threats and cruelties. They were cruel. They hurt me a lot."
Miss Erith's eyes suddenly dimmed as she watched him, and she hastily bent her head over the pad.
"Well," he went on, "the rest, as I say, is pure surmise. This is my conclusion: I think that for the last forty years the Huns have been busy with an astounding military enterprise. Of course, since 1870, the Boche has expected war, and has been feverishly preparing for it. All the world now knows what they have done—not everything that they have done, however.
"My conclusion is this: that, when Mount Terrible shrugged me off its northern flank, the snow slide carried me to an almost inaccessible spot of which even the Swiss hunters knew nothing. Or, if they did, they considered it impossible to reach from their own territory.
"From Germany it could be reached, but it was Swiss territory. At any rate I think I am the only civilian who has been there, and who has viewed from there this enormous work in which the Huns are engaged.
"And I belive that this mysterious, overwhelmingly enormous work is nothing less than the piercing—not of a mountain or a group of mountains—but of that entire part of Switzerland which lies between Germany and France.
"I believe that a vast military road, deep, deep, under the earth, is being carried by an enormous tunnel from far back on the German side of the frontier, under Mount Terrible, under all the mountains, hills, valleys, forests, rivers—under Switzerland, in fact—into French territory.
"I believe it has been building since 1871. I believe it is nearly finished, and that it will, on French territory, give egress to a Hun army debouching from Alsace, under Switzerland, into France behind the French lines. That part of the Franco-Swiss frontier is unguarded, unfortified, uninhabited. From there a Hun army can strike the French trenches from the rear—strike Toul, Nancy, Belfort, Verdun—why, the road is open to Paris that way—open to Calais, to England!"
"This is frightful!" cried the girl. "If such a dreadful—"
"Wait! I told you that it is merely a surmise. I don't know. I guess. Why I guess it I have told you…. They were savage with me—those Huns…. They got nothing out of me. I lied steadily, even when drunk. No, they got nothing out of me. I denied I had seen anything. I denied—and truly enough—that anybody had accompanied me. No, they wrenched nothing out of me—not by starving me, not by water torture, not by their firing-squads, not by blows, not even by making of me the drunkard I am."
The pencil fell from Miss Erith's hand and the hand caught McKay's, held it, crushed it.
"You're only a boy," she murmured. "I'm not much more than a girl. We've both got years ahead of us—the best of our lives."
"YOU have."
"You also! Oh, don't, don't look at me that way. I'll help you. We've got work to do, you and I. Don't you see? Don't you understand? Work to do for our Government! Work to do for America!"
"It's too late for me to—"
"No. You've got to live. You've got to find yourself again. This depends on you. Don't you see it does? Don't you see that you have got to go back there and PROVE what you merely suspect?"
"I simply can't."
"You shall! I'll make this right with you! I'll stick to you! I'll fight to give you back your will-power—your mind. We'll do this together, for our country. I'll give up everything else to make this fight."
He began to tremble.
"I—if I could—"
"I tell you that you shall! We must do our bit, you and I!"
"You don't know—you don't know!" he cried in a bitter voice, then fell trembling again with the sweat of agony on his face.
"No, I don't know," she whispered, clutching his hand to steady him. "But I shall learn."
"You'll learn that a drunkard is a dirty beast!" he cried. "Do you know what I'd do if anybody tried to keep me from drink? ANYBODY!—even you!"
"No, I don't know." She shook her head sorrowfully: "A mindless man becomes a demon, I suppose. … Would you—injure me?"
He was shaking all over now, and presently he sat up in bed and covered his head with one desperate hand.
"You poor boy!" she whispered.
"Keep away from me," he muttered, "I've told you all I know. I'm no further use…. Keep clear of me…. I'm sorry—to be—what I am."
"When I leave what are you going to do?" she asked gently.
"Do? I'll dress and go to the nearest bar."
"Do you need it so much already?"
He nodded his bowed head covered by the hand that gripped his hair: "Yes, I need it—badly."
She rose, loosened his clutch on her slender hand, picked up her muff:
"I'll be waiting for you downstairs," she said simply.
His face expressed sullen defiance as he passed through the waiting-room. Yet he seemed a little taken aback as well as relieved when Miss Erith did not appear among the considerable number of people waiting there for discharged patients. He walked on, buttoning his fur coat with shaky fingers, passed the doorway and stepped out into the falling snow. At the same moment a chauffeur buried in coon-skins moved forward touching his cap:
"Miss Erith's car is here, sir; Miss Erith expects you."
McKay hesitated, scowling now in his perplexity; passed his quivering hand slowly across his face, then turned, and looked at the waiting car drawn up at the gutter. Behind the frosty window Miss Erith gave him a friendly smile. He walked over to the curb, the chauffeur opened the door, and McKay took off his hat.
"Don't ask me," he said in a low voice that trembled slightly like a sick man's.
"I DO ask you."
