Godolphin, Volume VI by Edward Bulwer-lytton

No human heart ever beat with more pure and generous emotions, when freed from the political fever that burned within her (withering, for the moment, the chastened and wholesome impulses of her nature), than those which animated the heart of the queenly Constance. She sent that evening for the most celebrated physician in London -- that polished and courtly man who seems born for the maladies of the drawing-room, but who beneath so urbane a demeanour, conceals so accurate and profound a knowledge of the disorders of his unfortunate race. I say accurate and profound comparatively, for positive knowledge of pathology is what no physician in modern times and civilized countries really possesses. No man cures us -- the highest art is not to kill! Constance, then, sent for this physician, and, as delicately as possible, related the unfortunate state of Lucilla, and the deep anxiety she felt for her mental and bodily relief.

The physician promised to call the next day; he did so, late in the afternoon -- Lucilla was gone. Strange, self-willed, mysterious, she came like a dream, to warn, to terrify, and to depart. They knew not whither she had fled, and her Moorish handmaid alone attended her.
