In response to Nick’s questions, the physician assured him that Helga Lund had given no adequate explanation of her startling behavior of the night before. She had simply said that she had recognized some one in the audience, that the recognition had brought up painful memories, and that she had completely forgotten her lines and talked at random. She did not know what she had said or done.

Her physicians realized that she was keeping something back, and had pleaded with her to confide fully in them as a means of relieving her mind from the weight that was so evidently pressing upon it. But she had refused to do so, having declared that it would serve no good purpose, and that the most they could do was to restore her shattered nerves.

The detective was not surprised at this attitude, which, as a matter of fact, paved the way to an interview with the actress.

“In that case I think you will have reason to be glad I came,” he told Doctor Lightfoot. “I believe I know, in general, what happened last night, and if you will give me your permission to see Miss Lund alone for half an hour, I have hope of being able to induce her to confide in me. My errand does not reflect upon her in any way, nor does it imply the slightest danger or embarrassment to her, so far as I am aware. My real interest lies elsewhere, but you will readily understand how it might help her and reënforce your efforts if I could induce her to unbosom herself.”

“There isn’t any doubt about that, Carter,” was the doctor’s reply; “but it’s a risky business. She is in a highly excitable state, and uninvited calls from men of your profession are not apt to be soothing, no matter what their object may be. How do you know that some ghost of remorse is not haunting her. If so, you would do much more harm than good.”

“If she saw the person I think she saw in the audience last night,” Nick replied, “it’s ten to one that the remorse is on the other side—or ought to be. If I am mistaken, a very few sentences will prove it, and I give you my word that I shall do my best to quiet any fears my presence may have aroused, and withdraw at once. On the other hand, if I am right, I can convince her that I am her friend, and that I know enough to make it worth her while to shift as much of her burden as possible to me. If she consents, the tension will be removed at once, and she will be on the road to recovery. And, incidentally, I shall have gained some very important information.”

The detective was prepared, if necessary, to be more explicit with Doctor Lightfoot; but the latter, after looking Nick over thoughtfully for a few moments, gave his consent.

“I’ve always understood that you always know what you are about, Carter,” he said. “There is nothing of the blunderer or the brute about you, as there is about almost all detectives. On the contrary, I am sure you are capable of using a great deal of tact, aside from your warm sympathies. My colleague isn’t here now, and I am taking a great responsibility on my shoulders in giving you permission to see Miss Lund alone at such a time. She is a great actress, remember, and, if it is possible, we must give her back to the world with all of her splendid powers unimpaired. She is like a musical instrument of incredible delicacy, so, for Heaven’s sake, don’t handle her as if she were a hurdy-gurdy!”

“Trust me,” the famous detective said quietly.

“Then wait,” was the reply, and the physician hurried from the room.
