She had certainly lost her senses, though! Even if that word, that look, that act had passed between them, between the Adventurer and the White Moll, he still did not know that Gypsy Nan was the White Moll--and that was the one thing now that he must not know, and... Rhoda Gray halted suddenly, and stared along the hallway ahead of her, and up the short, ladder-like steps that led to the garret. Her ears--or was it fancy?--had caught what sounded like a low knocking up there upon her door. Yes, it came again now distinctly. It was dusk outside; in here, in the hall, it was almost dark. Her eyes strained through the murk. She was not mistaken. Something darker than the surrounding darkness, a form, moved up there. The knocking ceased, and now the form seemed to bend down and grope along the floor; and then, an instant later, it began to descend the ladder-like steps--and abruptly Rhoda Gray, too, moved forward. It wasn't Danglar. That was what had instantly taken hold of her mind, and she knew a sudden relief now. The man on the stairs--she could see that it was a man now--though he moved silently, swayed in a grotesquely jerky way as though he were lame. It wasn't Danglar! She would go to any length to track Danglar to his lair; but not here--here in the darkness--here in the garret. Here she was afraid of him with a deadly fear; here alone with him there would be a thousand chances of exposure incident to the slightest intimacy he might show the woman whom he believed to be his wife--a thousand chances here against hardly one in any other environment or situation. But the man on the stairs wasn't Danglar. She halted now and uttered a sharp exclamation, as though she had caught sight of the man for the first time. The other, too, had halted--at the foot of the stairs. A plaintive drawl reached her: “Don't screech, Bertha! It's only your devoted brother-in-law. Curse your infernal ladder, and my twisted back!” Danglar's brother! Bertha! She snatched instantly at the cue with an inward gasp of thankfulness. She would not make the mistake of using the vernacular behind which Gypsy Nan sheltered herself. Here was some one who knew that Gypsy Nan was but a role. But she had to remember that her voice was slightly hoarse; that her voice, at least, could not sacrifice its disguise to any one. Danglar had been a little suspicious of it until she had explained that she was suffering from a cold. “Oh!” she said calmly. “It's you, is it? And what brought you here?” “What do you suppose?” he complained irritably. “The same old thing, all I'm good for--to write out code messages and deliver them like an errand boy! It's a sweet job, isn't it? How'd you like to be a deformed little cripple?” She did not answer at once. The night seemed suddenly to be opening some strange, even premonitory, vista. The code messages! Their mode of delivery! Here was the answer! “Maybe I'd like it better than being Gypsy Nan!” she flung back significantly.
