"Oh, no, she was quite young and pretty," said the detective, laughing his happy, good-humored laugh.

"But surely——" began the listener.

"Mrs. Ernscliffe's maid was in disguise, both as to name and appearance," said Mr. Kidder, interrupting him. "Perhaps a bit of her history might interest you, sir, seeing that she has served you a good turn."

"I should like to hear it," said Captain Ernscliffe. "But wait a moment, Kidder, until I ring for lights. It is growing dark."

"Go on, Kidder, let me hear Elsie Gray's history."

"Well, sir, Elsie Gray's true name is Jennie Thorn, and she is not more than twenty years old.

"She was a poor farmer's daughter when this man whom she has tracked to his doom deceived and ruined her under a pretense of marriage.

"The poor girl went home to her parents, but her honest father drove her away with curses when he discovered her condition and learned her sad story.
