There could be no gross phrasing to Milly, in particular, of the probability that if she wasn't so proud she might be pitied with more comfort--more to the person pitying; there could be no spoken proof, no sharper demonstration than the consistently considerate attitude, that this marvellous mixture of her weakness and of her strength, her peril, if such it were, and her option, made her, kept her, irresistibly interesting. Kate's predicament in the matter was, after all, very much Mrs. Stringham's own, and Susan Shepherd herself indeed, in our Maeterlinck picture, might well have hovered in the gloaming by the moat. It may be declared for Kate, at all events, that her sincerity about her friend, through this time, was deep, her compassionate imagination strong; and that these things gave her a virtue, a good conscience, a credibility for herself, so to speak, that were later to be precious to her. She grasped with her keen intelligence the logic of their common duplicity, went unassisted through the same ordeal as Milly's other hushed follower, easily saw that for the girl to be explicit was to betray divinations, gratitudes, glimpses of the felt contrast between her fortune and her fear--all of which would have contradicted her systematic bravado. That was it, Kate wonderingly saw: to recognise was to bring down the avalanche--the avalanche Milly lived so in watch for and that might be started by the lightest of breaths; though less possibly the breath of her own stifled plaint than that of the vain sympathy, the mere helpless gaping inference of others. With so many suppressions as these, therefore, between them, their withdrawal together to unmask had to fall back, as we have hinted, on a nominal motive--which was decently represented by a joy at the drop of chatter. Chatter had in truth all along attended their steps, but they took the despairing view of it on purpose to have ready, when face to face, some view or other of something. The relief of getting out of harness--that was the moral of their meetings; but the moral of this, in turn, was that they couldn't so much as ask each other why harness need be worn. Milly wore it as a general armour.
