“My first conjecture was that possibly there had been some passages between this young lady and the old soldier, which the former had now confessed to the wife. That would account for the angry return, and also for the girl’s denial that anything had occurred. Nor would it be entirely incompatible with most of the words overheard. But there was the reference to David, and there was the known affection of the colonel for his wife to weigh against it, to say nothing of the tragic intrusion of this other man, which might, of course, be entirely disconnected with what had gone before. It was not easy to pick one’s steps, but, on the whole, I was inclined to dismiss the idea that there had been anything between the colonel and Miss Morrison, but more than ever convinced that the young lady held the clue as to what it was which had turned Mrs. Barclay to hatred of her husband. I took the obvious course, therefore, of calling upon Miss M., of explaining to her that I was perfectly certain that she held the facts in her possession, and of assuring her that her friend, Mrs. Barclay, might find herself in the dock upon a capital charge unless the matter were cleared up.

“Miss Morrison is a little ethereal slip of a girl, with timid eyes and blond hair, but I found her by no means wanting in shrewdness and common sense. She sat thinking for some time after I had spoken, and then, turning to me with a brisk air of resolution, she broke into a remarkable statement which I will condense for your benefit.

“ ‘I promised my friend that I would say nothing of the matter, and a promise is a promise,’ said she; ‘but if I can really help her when so serious a charge is laid against her, and when her own mouth, poor darling, is closed by illness, then I think I am absolved from my promise. I will tell you exactly what happened upon Monday evening.

“ ‘We were returning from the Watt Street Mission about a quarter to nine o’clock. On our way we had to pass through Hudson Street, which is a very quiet thoroughfare. There is only one lamp in it, upon the left-hand side, and as we approached this lamp I saw a man coming towards us with his back very bent, and something like a box slung over one of his shoulders. He appeared to be deformed, for he carried his head low and walked with his knees bent. We were passing him when he raised his face to look at us in the circle of light thrown by the lamp, and as he did so he stopped and screamed out in a dreadful voice, “My God, it’s Nancy!” Mrs. Barclay turned as white as death and would have fallen down had the dreadful-looking creature not caught hold of her. I was going to call for the police, but she, to my surprise, spoke quite civilly to the fellow.

“ ‘ “I thought you had been dead this thirty years, Henry,” said she in a shaking voice.

“ ‘ “So I have,” said he, and it was awful to hear the tones that he said it in. He had a very dark, fearsome face, and a gleam in his eyes that comes back to me in my dreams. His hair and whiskers were shot with gray, and his face was all crinkled and puckered like a withered apple.

“ ‘ “Just walk on a little way, dear,” said Mrs. Barclay; “I want to have a word with this man. There is nothing to be afraid of.” She tried to speak boldly, but she was still deadly pale and could hardly get her words out for the trembling of her lips.

“ ‘I did as she asked me, and they talked together for a few minutes. Then she came down the street with her eyes blazing, and I saw the crippled wretch standing by the lamp-post and shaking his clenched fists in the air as if he were mad with rage. She never said a word until we were at the door here, when she took me by the hand and begged me to tell no one what had happened.
