They were both out of breath from their rush; and to find themselves alone in the dark, and in a place where they had no right to be, was delightful. They sat quiet for a moment, leaning against each other recovering their breath, and then there happened something which, notwithstanding Kitty’s intense preoccupation with her own affairs, gave her such a prick of still more vivid curiosity as roused every sense and faculty in her. She became all ear and all observation in a moment. There was a soft sound as of a door opening on the other side of the room--the side that was in the shade--and then after a moment a voice asked, ‘Is it you?’ Walter (the idiot) suppressed with pain a giggle, and only suppressed it because Kitty flung herself upon him, putting one hand upon his mouth and clutching his coat with the other to keep him quiet. She held her breath and became noiseless as a mouse--as a kitten in the moment before a spring. The voice was a man’s voice, with something threatening in its tone. ‘How long do you think this is going to last?’ he said. Oh, what a foolish thing a boy is! Walter shook with laughter, while she listened as if for life and death. Then there was a pause. Again the voice asked anxiously, ‘Is it you?’--another pause, and then the soft closing of the door more cautiously than it had been opened. Walter rose up from the sofa as soon as the door was shut. ‘I must get my laugh out,’ he whispered, sweeping Kitty out into the passage. Oh, that foolish, foolish boy! As if it were a laughing matter! A man, a stranger, asking somebody how long ‘this’ was to last! How long what was to last? And who could he be? ‘Oh, Wat, you might have stayed a moment!’ Kitty said, exasperated; ‘you might have kept quiet! Perhaps he would have said something more. Who could he be?’ ‘It is no business of ours,’ said Walter; ‘one of the servants, I suppose. Let’s go upstairs again, Kitty. We have no business here.’ ‘Oh, don’t be so silly,’ cried Kitty; ‘we must find a quiet place, for I’ve scores of things to tell you. There is a room at the other end with a light in it. Let us go there.’ Their footsteps sounded upon the stone passage, and Kitty’s dress rustled--there could be no eavesdropping possible there. She went on a step in front of him and pushed open a door which was ajar; then Kitty gave a little shriek and fell back, but too late. Mrs. Blencarrow, in all her splendour for the ball, was standing before the fire. It was a plainly-furnished room, with a large writing-table in it, and shelves containing account books and papers--the business-room, where nobody except the tenants and the workpeople ever came in. To see her standing there, with all her diamonds flashing in the dimness, was the strangest sight. ‘Who is there?’ she cried, with an angry voice; then, ‘Kitty! What are you doing here?’
