Hilda rose at once with stately alacrity. Nothing could have pleased her better. She went to the piano, and, to the awe and astonishment of Mrs. Campbell Moncrieff, took out an arrangement of the Fijian war-dance from 'The Primate of Fiji.' It suited her brilliant slap-dash style of execution admirably; and she felt she had never played so well in her life before. The presence of the composer, which would have frightened and unnerved most girls of her age, only made Hilda Tregellis the bolder and the more ambitious. Here was somebody at least who knew something about it; none of your ordinary fashionable amateurs and mere soulless professional performers, but the very man who had made the music--the man in whose brain the notes had first gathered themselves together into speaking melody, and who could really judge the comparative merits of her rapid execution. She played with wonderful verve and spirit, so that Lady Exmoor, seated on the side sofa opposite, though shocked at first at Hilda's choice of a piece, glanced more than once at the wealthiest young commoner present (she had long since mentally resigned herself to the prospect of a commoner for that poor dear foolish Hilda), and closely watched his face to see what effect this unwonted outburst of musical talent might succeed in producing upon his latent susceptibilities. But Lady Hilda herself wasn't thinking of the wealthy commoner; she was playing straight at Arthur Berkeley: and when she saw that Arthur Berkeley's mouth had melted slowly into an approving smile, she played even more brilliantly and better than ever, after her bold, smart, vehement fashion. As she left the piano, Arthur said, 'Thank you; I have never heard the piece better rendered.' And Lady Hilda felt that that was a triumph which far outweighed any number of inane compliments from a whole regiment of simpering Algies, Monties, and Berties. 'You can't say any evening, then, Mr. Berkeley?' she said once more, as she held out her hand to him to say 'Good-night' a little later: 'not any evening at all, or part of an evening? You might really reconsider your engagements.' Arthur hesitated visibly. 'Well, possibly I might manage it,' he said, wavering, 'though, I assure you, my evenings are very much more than full already.' 'Then don't make it an evening,' said Lady Hilda, pressingly. 'Make it lunch. After all, Mr. Berkeley, it's we ourselves who want to see you; not to show you off as a curiosity to all the rest of London. We have silly people enough in the evenings; but if you'll come to lunch with us alone one day, we shall have an opportunity of talking to you on our own account.'
