The landing at the top of the stairs in Audley Court was always dark; but it seemed darker than ever to Hyacinth while he fumbled for the door-latch, after he had heard Rose Muniment's penetrating voice bid him come in. During that instant his ear caught the sound — if it could trust itself — of another voice, which prepared him, a little, for the spectacle that offered itself as soon as the door (his attempt to reach the handle, in his sudden agitation, proving fruitless), was opened to him by Paul. His friend stood there, tall and hospitable, saying something loud and jovial, which he didn't distinguish. His eyes had crossed the threshold in a flash, but his step faltered a moment, only to obey, however, the vigour of Muniment's outstretched hand. Hyacinth's glance had gone straight, and though with four persons in it Rosy's little apartment looked crowded, he saw no one but the object of his quick preconception — no one but the Princess Casamassima, seated beside the low sofa (the grand feature introduced during his absence from London), on which, arrayed in the famous pink dressing-gown, Miss Muniment now received her visitors. He wondered afterwards why he should have been so startled; for he had said, often enough, both to himself and to the Princess, that so far as she was concerned he was proof against astonishment; it was so evident that, in her behaviour, the unexpected was the only thing to be looked for. In fact, now that he perceived she had made her way to Camberwell without his assistance, the feeling that took possession of him was a kind of embarrassment; he blushed a little as he entered the circle, the fourth member of which was inevitably Lady Aurora Langrish. Was it that his intimacy with the Princess gave him a certain sense of responsibility for her conduct in respect to people who knew her as yet but a little, and that there was something that required explanation in the confidence with which she had practised a descent upon them?
