opened the door, she heard a strange sound rising above the notes of the music; it was that, perhaps, most terrible of all sounds, the unbidden, irresistible groan, rising from a man's tortured heart; and it came from the young man's room.

Startled, chilled, by the sound, she wondered that she could hear it so plainly; then she saw that the door opposite was slightly ajar; evidently the visitor had failed to close it. Celia waited, with the familiar horror, the tense expectation, for a repetition of the groan. It came. Obeying an impulse, a womanly impulse, to fly to the call of such poignant distress, Celia crossed the corridor softly and opened the door.

By the light of a single candle, she saw the young man seated at a table; his head was resting, face downward, on one arm; his whole attitude was eloquent of despair; but it was not this abandonment of grief which caused her to thrill with quick terror; it was because the hand held clenched in its grasp a revolver.

Most women have a horror of firearms; Celia stood motionless, her eyes fixed on the shining, deadly weapon, as if it were a poisonous snake. She wanted to cry out, to rush at the beastly thing and snatch it from the hand that gripped it; but she felt incapable of speech or movement; she could only stare with distended eyes at the revolver and the head lying on the arm.

So quick, so noiseless had been her entrance, that the man had not heard her; but presently, after a few moments which seemed years to her, he became conscious of her presence. He raised his head slowly and looked at her with vacant eyes, as if he were half-dazed and were asking himself if she were a vision. The movement released Celia from her spell; a pang of pity smote her at the sight of the white, drawn face, the hopeless despair in the young fellow's eyes; her womanly compassion, that maternal instinct which the youngest of girl-children possesses, gave her courage. She leant forward, loosened the stiff, cold fingers and took the revolver from them. He submitted, as if he were still only half-conscious of her presence, and her action; and he glanced at his empty hand, at the revolver in hers, and then at her face. Guided once more by impulse, Celia closed the door, then went back and seated herself in a chair on the other side of the table; and so, face to face, they regarded each other in silence.

The man broke it.

"How—how did you know?" he asked. He spoke almost in a whisper, as a man speaks who is recovering from an anæsthetic.

"I heard you—groan," said Celia, also almost in a whisper.

"You did?" he said, more clearly, and with disgust. "I must have groaned pretty loudly." His self-contempt was evident.

There was a pause, then he said: "You are the girl who lives opposite?" A flicker of irritation and impatience shone in his eyes. "Why do you interfere? It is no business of yours!"

"Yes, it is," she said, and there was something like a note of anger in her voice; for it seemed to her that he was extremely ungrateful. "It is the duty of anyone to prevent a man making—a—a fool of himself. You ought to be ashamed."

Unwittingly, she had used the right tone. He leant back in the chair and stared at her with a mixture of resentment and amusement.

"You have plenty of confidence, anyhow, young lady," he said.

"And you have none," retorted Celia, with a dash of colour. "Fancy a man of your age trying to—to kill himself!"

"My age!" He laughed mirthlessly, ironically. "You talk to me, look at me, as if I were a boy."

"You are not much more," said Celia; "and a foolish one into the bargain."

He pushed impatiently the short lock of hair from his forehead, which was dank with sweat.

"Be that as it may," he said, "you have interfered most unwarrantably in a matter which does not concern you. All the same, I suppose you expect me to say that I am obliged to you. Well, I'm not; I don't like being interfered with, especially—by a woman. You come into my room——" He tried to rise with an air of dignity, but he sank back, as if he were weak, and with his arms extended along those of the chair regarded her with a grim smile of whimsicality. "Well, I suppose I ought to say I am obliged to you. Consider that I have said it and—pray, don't let me keep you."

Celia rose, the revolver still in her hand.

"Good night," she said.

"Here!" he called out to her, wearily; "give me back that thing; put it down."

"Certainly not," said Celia, with decision. "You are not fit to be trusted with it."

"Oh, am I not?" he said, sarcastically.

"You know you are not. What were you doing with it, what were you going to do with it, when I came in?" she demanded.

"What an unnecessary question," he retorted. "I was going to shoot myself, of course."

"Exactly. That is why I am taking it away from you."

"You are very clever," he said, with an attempt at sarcasm. "I can go out and buy another. No, I can't"—he laughed rather quaveringly—"I haven't the coin. Put that revolver down, young lady, and leave me alone."

"I shall do nothing of the kind," said Celia, her eyes bright, her lips drawn straight. "I mean, that I am going to take the revolver. And I am not sure that I ought to leave you alone. If I do, will you promise me——"

"That I won't try to kill myself in some other way? I will promise you nothing of the sort; you don't know what you are asking. But, as I said before, I don't want to detain you. In fact, if you knew—what I am——" his voice faltered for a moment—"you would clear out without any urging on my part."

There was a pause, then: "What are you?" asked Celia, in a low voice.

"I am a forger," he replied, after another pause.

The colour left Celia's face, her lips quivered for a moment, but her eyes did not turn from him; and his eyes, after an attempt on his part to keep them steady, drooped before her intent gaze.

There was a silence which could be felt; then Celia said, very slowly, very quietly:

"I don't believe you."

CHAPTER II

The colour rose to the young man's pallid face; he leant back and, with narrowed eyes, regarded her, for the first time, with curiosity and interest. It may be said that, up to that moment, he had not realized her personality; she was just a something, a nuisance in the shape of a girl, which had come between him and a shameful death. Of course, he had seen Celia in the corridor now and again, had noticed vaguely that his opposite neighbour was young and graceful and pretty—no man, especially one of his age, could fail to notice such palpable facts—but he had been too absorbed in his own affairs to take any interest in her. Now, surprised by her courage, he regarded her curiously, and he saw that she was not only pretty, but quite beautiful. He took in the clear oval of her face, the soft waves of dark hair which garlanded the low forehead, puckered now by lines of decision, the blue-grey eyes almost violet in the intensity of her gaze, the lips which, he felt, could smile with infinite tenderness, though now set tightly.

Yes; this young woman who had come at the sound of his groan of despair, who now sat opposite him, gripping the revolver which she had forced from his hand, was very beautiful, and, obviously, very brave; he saw, too, that she was a lady, that she was different from most of the girls who lived in the Buildings. In that flash of scrutiny, he took in even the details of her dress, and knew that, plain as it was, it had come from a good house, probably from Paris itself; there were no cheap rings on the well-formed, but not too small, hands; he realized that he was confronting the embodiment of the three qualities most desirable—youth, beauty, strength; and he was conscious of a reluctant thrill of admiration. His eyes sank, and, involuntarily, he sighed. For he was thinking of another woman.

"Did you hear what I said?" asked Celia, in a low
