But although Gregory saw so little of her, although she was not in his life as a presence, he felt her in it as an influence. She might have been the invisible but portentous comet moving majestically on the far confines of his solar system; and one accounted for oddities of behaviour in the visible planets by inferring that the comet was the cause of them. If he saw very little of Madame von Marwitz, he saw, too, much less of his twin planet, Karen. It was not so much that Karen's course was odd as that it was altered. If Madame von Marwitz sent for her very intermittently, she had, all the same, in all her life, as she told Gregory, never seen so much of her guardian. She frankly displayed to him the radiance of her state, wishing him, as he guessed, to share to the full every detail of her privileges, and to realise to the full her gratitude to him for proving so conclusively to Tante that there was none of the selfishness of love in him. Tante must see that he made it very easy for her to go to her, and Gregory derived his own secret satisfaction from the thought that Karen's radiance was the best of retorts to Madame von Marwitz's veiled intimations. As long as she made Karen happy and let him alone, he seemed to himself to tell her, he would get on very well; and he suspected that her clutch of Karen would soon loosen when she found it unchallenged. In the meantime there was not much satisfaction for him elsewhere. Karen's altered course left him often lonely. Not only had the readings of Political Economy, begun with so much ardour in their spare evenings, almost lapsed for lack of consecutiveness; but he frequently found on coming home tired for his tea, and eager for the sight of his wife, a little note from her telling him that she had been summoned to Mrs. Forrester's as Tante was "with Fafner in his cave" and wanted her. Fafner was the name that Madame von Marwitz gave to her moods of sometimes tragic and sometimes petulant melancholy. Karen had told him all about Fafner and how, in the cave, Tante would lie sometimes for long hours, silent, her eyes closed, holding her hand; sometimes asking her to read to her, English, French, German or Italian poetry; their range of reading always astonished Gregory. He gathered, too, from Karen's confidences, how little, until now, he had gauged the variety of the great woman's resources, how little done justice to her capacity for being merely delightful. She could be whimsically gay in the midst of melancholy, and her jests and merriment were the more touching, the more exquisite, from the fact that they flowered upon the dark background of the cave. It was, he saw, with a richer flavour that Karen tasted again the charm of old days, when, after some great musical or social event, in which the girl had played her part of contented observer, they had laughed together over follies and appreciated qualities, in the familiar language of allusion evolved from long community in experience.
