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. "Who are you?" he repeated hoarsely. He stood with a curious sense of being supported only by the grasp which he had taken of the back of the chair, feeling himself a mere bundle of impulses and sensations, hardly able to keep himself from flight, hardly able to keep from falling down at the feet of this intruder, but holding to a sort of self-restraint by his grasp upon the chair. Naturally, however, his nerves steadied as the moments passed. The first extreme shock of surprise wore away. There was nothing to alarm the most timid in the countenance upon which he gazed. It was that of a handsome man who had scarcely turned middle age, with grey but not white hair very thin on the forehead and temples, a high delicate aquiline nose, and colourless complexion. His mouth closed somewhat sternly, but had a faint melting of a smile about it, by movements which were ingratiating and almost sweet. The chief thing remarkable about the stranger, however, besides the extraordinary suddenness of his appearance, was the perfect composure with which he sat, like a man who not only was the most important person wherever he went, but also complete master of the present scene. It was the young man who was the intruder, not he.
