He saw and he heard, but his eyes clung to but one point, his ears listened for but one cry. There at the extremity of a cornice, clinging to a bending beam, was the figure again — the woman of the ice-floe and the desert. She seemed nearer now. He could see the straining muscles of her arm, the white despair of her set features. He wished to call aloud to her not to look down — then, as the sudden darkness yielded to another illuminating gleam, his mind changed and he would fain have begged her to look, slip, and end all, for subtly, quietly, ominously somewhere below her feet, he had caught the glimpsing of a feathery line of smoke curling up from the lower d­bris. Flame was there; a creeping devil which soon ——
