"Has your daughter any enemy, who might envy her her success, and wish to deprive her of it?" he asked.

"None, that I know of. But since these two letters came, I feel convinced that someone, whom, I cannot imagine, does feel that way toward her, and that on account of it she is in the gravest danger. Don't you think so, Mr. Duvall?"

"I think it highly probable. And what, Mrs. Morton, would you like to have me do in the matter?"

"Why—come to New York, take up the case, and find out who these wretches are, so that they may be prevented from doing my daughter any harm. There is no time to lose. They may carry out their threats at any moment. You will observe that in the first letter they said that her beauty would be destroyed 'within thirty days.' One of those days has already passed. To-day is the second. At most, we have but twenty-eight days left in which to find out who is responsible for this outrage. Investigation may consume a great deal of time. I hope that you will consent to come to New York and take charge of the matter at once. I am returning this afternoon, as soon as I can get a train. Can you not return with me? As for the matter of expense, I place no limit upon it. There is nothing I would not sacrifice, to save my daughter from the fate they have threatened. Think what it would mean, Mr. Duvall. A young, beautiful, innocent girl, scarcely more than a child, to go through life with her beauty taken from her, made hideous by some fiendish device, blinded and scarred by acid, her features crushed—gashed by some sudden blow. Can you imagine anything more terrible?"

Duvall thought for moment of his own lovely child, now almost three years old, and shuddered. Bank burglaries, thefts of jewels, seemed relatively of small importance compared with such a situation as this. His feelings of chivalry rose. He felt a strong desire to help this young girl.

"Here is her picture," Mrs. Morton continued, taking a photograph from her handbag and extending it to Duvall.

The latter gazed at the charming features of the young actress, and nodded.

"She is lovely—exquisite," he murmured. "I don't wonder you feel as you do. I did not intend to take up any detective work at this time, but I have decided to assist you in this matter in any way that I can."

"Oh—thank you, Mr. Duvall." There were tears in Mrs. Morton's anxious eyes. "I can never repay you for your kindness—never. But if you can save Ruth from these scoundrels, I will gladly spend——"

"Never mind about that, Mrs. Morton," Duvall observed, with a friendly smile. "It is scarcely a question of money with me. If I had not felt a keen interest in your daughter's welfare, I should not have agreed to take up the matter at all. As it is, you need not worry about the expense. I am going to take the case largely because it has interested me, and it will be a pleasure to work it out, not only on your daughter's account, but on my own. You know, to me, such matters are of absorbing interest, like the solving of some complex and baffling puzzle."
