"But, my Lord!" burst out the man, "d'you mean to say you--you went down there--alone?"
Once more the girl laughed.
"Not alone," she answered. "One of the automatics was kind enough to bear me company. Of course the main stairway was impassable. But I found another way, off through the east end of the building and down some stairs we haven't used at all, yet. They may be useful, by the way, in case of--well--a retreat. Once I'd reached the arcade, the rest was easy. I had that leather rope tied to the kettle handle, you see. So all I had to do was--"
"But the Horde! The Horde?"
"None of them down there, now--that is, alive. None when I was there. All at the war-council, I imagine. I just happened to strike it right, you see. It wasn't anything. We simply had to have water, so I went and got some, that's all."
"That's all?" echoed Stern, in a trembling voice. "That's--all!"
Then, lest she see his face even by the dim light through the window, he turned aside a minute. For the tears in his eyes, he felt, were a weakness which he would not care to reveal.
But presently he faced the girl again.
"Beatrice," said he, "words fall so flat, so hopelessly dead; they're so inadequate, so anticlimactic at a time like this, that I'm just going to skip them all. It's no use thanking you, or analyzing this thing, or saying any of the commonplace, stupid things. Let it pass. You've got water, that's enough. You've made good, where I failed. Well--"
His voice broke again, and he grew silent. But she, peering at him with wonder, laid a hand upon his shoulder.
"Come," said she, "you must eat something, too. I've got a little supper ready. After that, the Pulverite?"
He started as though shot.
"That's so! I can make it now!" cried he, new life and energy suffusing him. "Even with my one hand, if you help me, I can make it! Supper? No, no! To work!"
But she insisted, womanlike; and he at last consented to a bite. When this was over, they began preparations for the manufacture of the terrible explosive, Stern's own secret and invention, which, had not the cataclysm intervened, would have made him ten times over a millionaire. More precious now to him, that knowledge, than all the golden treasures of the dead, forsaken world!
"We've got to risk a light," said he. "If it's turned low, and shaded, maybe they won't learn our whereabouts. But however that may be, we can't work in the dark. It would be too horribly perilous. One false move, one wrong combination, even the addition of one ingredient at the improper moment, and--well--you understand."
