Katherine had been practising her old gift of reading music almost every evening when alone and was now very proficient. Lady Garribardine knew this, because she had sent for her secretary to play to her several times in her sitting-room when she was there without visitors and was suffering from rheumatism. Mr. Strobridge introduced Katherine to the visitor, who turned out to be the beautiful lady he had walked with in the rose garden; and they got on extremely well. It was the first time Katherine had ever chatted, as practically an equal, alone with a member of society except her employer. The stranger was charming, and insisted that she should come down to play again in the drawing-room after dinner. Another occasion for the black frock to be worn! And a chance not to be wasted for observation as to behaviour! Katherine, when evening came, made herself look her very best, and was waiting demurely by the piano as the ladies entered the room. From this position she attracted no attention until some of them wanted to play. The guest she had accompanied was again graciously sweet to her, and some of the others joined in the conversation while they strummed and pulled about the songs. There was something arresting in Katherine's type which called for notice when people were near enough to observe details of her mousy fair hair that had no touch of gold in it, but always glistened grey, and her wonderfully pale skin and dark brows, giving her strange eyes that intense shadowed mystery which aroused interest. Gerard, who joined the party by the piano when the men came in, watched her silently. She had studied to obtain an air of distinction, and Gerard, whose love did not blind his fastidious critical faculties, remarked that there was a real advance in this direction since the Christmas night when he had last seen her in evening dress. She did not look so sullen either and answered with fluency and ease when she was addressed, and not in the monosyllabic fashion of former days. An elderly politician spoke to her. He seemed delighted with her conversation, and indicated by a gesture that she should sit down beside him when the songs were over and she was about to slip away out of the room. Katherine was not at all certain whether she ought to stay or not, but Lady Garribardine at that moment came up and said casually, "You must not go to bed yet, Miss Bush, perhaps they will sing again; wait here and talk to Sir John." And so bidden, Katherine was delighted to obey and used her intelligence to be agreeable and sympathetic. Gerard continued to watch her and felt pride in her. "Your secretary is having a great success to-night, isn't she, Seraphim?" he said to his aunt.
