Maggie, from the end, saw her stop before one of the windows to look at the group within, and then saw her come nearer and pause again, still with a considerable length of the place between them.
Yes, Charlotte had seen she was watching her from afar, and had stopped now to put her further attention to the test.

Her face was fixed on her, through the night; she was the creature who had escaped by force from her cage, yet there was in her whole motion assuredly, even as so dimly discerned, a kind of portentous intelligent stillness.

She had escaped with an intention, but with an intention the more definite that it could so accord with quiet measures.

The two women, at all events, only hovered there, for these first minutes, face to face over their interval and exchanging no sign; the intensity of their mutual look might have pierced the night, and Maggie was at last to start with the scared sense of having thus yielded to doubt, to dread, to hesitation, for a time that, with no other proof needed, would have completely given her away.
How long had she stood staring ?--a single minute or five?
Long enough, in any case, to have felt herself absolutely take from her visitor something that the latter threw upon her, irresistibly, by this effect of silence, by this effect of waiting and watching, by this effect, unmistakably, of timing her indecision and her fear.

If then, scared and hanging back, she had, as was so evident, sacrificed all past pretences, it would have been with the instant knowledge of an immense advantage gained that Charlotte finally saw her come on.
