Burgoyne has chartered a fiacre, with a horse as little lame as is ever to be found in Florence, and in this vehicle they are presently rolling along. None of them are in very exuberant spirits. Burgoyne is as well aware as if her sensitive lips had put the fact into words, that for Elizabeth the pleasure of the outing has evaporated with the absence of Byng, and that it is only the soft-hearted shrinking of a sweet nature from inflicting mortification on a fellow-creature that has set her opposite to him in her white gown. He has never seen her dressed in white before, and says to himself that it was for Byng's sake that she has made herself so summer-fine. But even if it be so, it is not Byng who is profiting by it. It is for him, not Byng, that the large Italian light is glorifying its thin fabric. Lily-pure, snow-clean she looks, sitting under her sunshade; and he sits over against her in a stupid silence. It seems to him as if his only safety were in silence, as if, did he speak at all, he must put into brutal words the brutal questions that are dinging in his head, that seem knocking for utterance against the gate of his set teeth. "What is the 'screw loose'? How is she an 'unfortunate girl'? Why have they 'never held up their heads since'? Since what?" He looks, in a fierce perplexity, from one to the other of those delicately poised heads, held aloft with such modest dignity. Surely it is beyond the bounds of possibility that any heavily hideous shame or leaden disgrace can ever have weighed upon them! Probably the intensity of his thought has given an intensity to his look, of which he is unaware; for he presently finds the soft veiled voice of Elizabeth--Elizabeth who has hitherto been as mute as himself--addressing him: "How very grave you look! I wonder what you are thinking of?" The question, striking in so strangely pat, brings him back with a start. For a second an almost overpowering temptation assails him to tell her what is the object of his thought, to answer her with that whole and naked truth which we can so seldom employ in our intercourse with our fellow-men. But one glance at her innocent face, which has a vague trouble in it, chases the lunatic impulse, though he dallies with the temptation to the extent of saying: "Would you really like to know? Do you really wish me to tell you?" He looks at her penetratingly as he puts the question. Before either his eyes or his manner she shrinks. "Oh, no--no!" she cries with tremulous haste, "of course not! I was only joking. What business have I with your thoughts? I never wish to know people's thoughts; if their looks and words are kind, that is all that concerns me!" He relapses into silence; but her words, and still more the agitated manner in which they are pronounced, make a vague yet definite addition to the disquiet of his soul.
