Fire-escapes, she knew, led, if followed long enough, to the ground: and she decided to climb to safety down this one. It was only when she had descended as far as the ninth floor that, glancing below her, she discovered that this particular fire-escape terminated not, as she had supposed, in some back-alley, but in the gaily-lighted out-door premises of a restaurant, half the tables of which were already filled.
This sight gave her pause. In fact, to be accurate, it froze her stiff. Nor was her agitation without reason. Those of the readers of this chronicle who have ever thrown pepper in a policeman's face, and skimmed away down a fire-escape, are aware that fire-escapes, considered as a refuge, have the defect of being uncomfortably exposed to view. At any moment, felt Mrs. Waddington, the policeman might come to the edge of the roof and look down; and to deceive him into supposing that she was merely a dust-bin or a milk-bottle was, she knew, beyond her histrionic powers.
