"Thank you," she said. Then, with frightened perplexity: "I don't know where to go. I never was in this city before. If you will kindly tell me how to get somewhere--suppose to a railroad station--and yet--no, I have no money--and"--then with a sudden little movement of dismay--"and I have no hat! Oh!"

The young man felt a strong desire to shield this girl so unexpectedly thrown on his mercy. Yet vague fears hovered about the margin of his judgment. Perhaps she was a thief or an adventuress. It might be that he ought to let her get out of the odd situation she appeared to be in, as best she might. Yet even as the thought flashed through his mind he seemed to hear an echo of her words, "I saw you were a gentleman," and he felt incapable of betraying her trust in him.

The girl was speaking again: "But I must not trouble you any more. You have been very kind to get me out of that dreadful place. If you will just stop the carriage and let me out, I am sure I can take care of myself."

"I could not think of letting you get out here alone. If you are in danger, I will help you." The warmth of his own words startled him. He knew he ought to be more cautious with a stranger, but impetuously he threw caution to the winds. "If you would just tell me a little bit about it, so that I should know what I ought to do for you----"

"Oh, I must not tell you! I couldn't!" said the girl, her hand fluttering up to her heart, as if to hold its wild beating from stifling her. "I am sorry to have involved you for a moment in this. Please let me out here. I am not frightened, now that I got away from that terrible tunnel. I was afraid I might have to go in there alone, for I didn't see any way to get up the bank, and I couldn't go back."

"I am glad I happened to be there," breathed the young man fervently. "It would have been dangerous for you to enter that tunnel. It runs an entire block. You would probably have been killed."

The girl shut her eyes and pressed her fingers to them. In the light of the street lamps, he saw that she was very white, and also that there were jewels flashing from the rings on her fingers. It was apparent that she was a lady of wealth and refinement. What could have brought her to this pass?
