"Fancy me in the character of a rapacious landlord, turning a whole community out of doors!" he said to himself, concocting the imaginary letter, and laughed aloud with a thrill of indignation.

Next moment he started violently, and turned round with a wild rush of blood to his head, and that sort of rallying and huddling together of all the forces of his mind which one feels in a sudden catastrophe. It was, however, no loud alarm that had sounded. It was the clear and distinct vibration of a voice close to him, replying calmly to his thought.

"Is there anything special in you to disqualify you for doing a disagreeable duty?" some one said.

Walter had started back at the first sound, his heart giving a bound in him of surprise—perhaps of terror. He had meant to take that great chair by the fire as soon as he had taken his book from the shelf, so that it must (he said to himself in instantaneous self-argument) have been vacant then. It was not vacant now. A gentleman sat there, with his face half turned towards the light looking towards the young man; his attitude was perfectly easy, his voice a well-bred and cultivated voice. There seemed neither hurry nor excitement about him. He had not the air of a person newly entered, but rather of one who had been seated there for some time at his leisure, observing what was going on. He lifted his hand with a sort of deprecating yet commanding gesture.

"There is no occasion," he said, in his measured voice, "for alarm. I have no intention of harming you, or any one. Indeed I am not aware that I have any power of harm."

Never in his life before had Walter's soul been swept by such violent sensations. He had an impulse of flight and of deadly overwhelming terror, and then of sickening shame at his own panic. Why should he be afraid? He felt dimly that this moment was the crisis of his life, and that if he fled or retreated he was lost. He stood his ground, grasping the back of a chair to support himself.

"Who are you?" he said.

"That is a searching question," said the stranger, with a smile. "We will come to it by and by. I should like to know in the first place what there is in you which makes it impossible to act with justice in certain circumstances?"

The air of absolute and calm superiority with which he put this question was beyond description.

Walter felt like a criminal at the bar.
