She had been quick in her preparation, in spite of the flow of the tide that sometimes took away her breath; but a pause, once more, was still left for her to make, a pause, at the top of the stairs, before she came down to him, in the span of which she asked herself if it weren't thinkable, from the perfectly practical point of view, that she should simply sacrifice him.

She didn't go into the detail of what sacrificing him would mean--she didn't need to; so distinct was it, in one of her restless lights, that there he was awaiting her, that she should find him walking up and down the drawing-room in the warm, fragrant air to which the open windows and the abundant flowers contributed; slowly and vaguely moving there and looking very slight and young and, superficially, manageable, almost as much like her child, putting it a little freely, as like her parent; with the appearance about him, above all, of having perhaps arrived just on purpose to SAY it to her, himself, in so many words: "Sacrifice me, my own love; do sacrifice me, do sacrifice me!" Should she want to, should she insist on it, she might verily hear him bleating it at her, all conscious and all accommodating, like some precious, spotless, exceptionally intelligent lamb.

The positive effect of the intensity of this figure, however, was to make her shake it away in her resumed descent; and after she had rejoined him, after she had picked him up, she was to know the full pang of the thought that her impossibility was MADE, absolutely, by his consciousness, by the lucidity of his intention: this she felt while she smiled there for him, again, all hypocritically; while she drew on fair, fresh gloves; while she interrupted the process first to give his necktie a slightly smarter twist and then to make up to him for her hidden madness by rubbing her nose into his cheek according to the tradition of their frankest levity.
From the instant she should be able to convict him of intending, every issue would be closed and her hypocrisy would have to redouble.

The only way to sacrifice him would be to do so without his dreaming what it might be for.

She kissed him, she arranged his cravat, she dropped remarks, she guided him out, she held his arm, not to be led, but to lead him, and taking it to her by much the same intimate pressure she had always used, when a little girl, to mark the inseparability of her doll--she did all these things so that he should sufficiently fail to dream of what they might be for.
XXIX There was nothing to show that her effort in any degree fell short till they got well into the Park and he struck her as giving, unexpectedly, the go-by to any serious search for the Principino.
