"Richard!" she exclaimed, "I'm so glad to see you. It has been ages. What's the matter with you? You look dreadfully blue." Duvall threw himself into a chair. "I'm a bit disgusted with myself," he said. "What about? I may ask you now, may I not? Is it about that wretched Morton case? I must talk to you about that. May I? You see, you rather got me into it, last night, and I got myself into it, too, by coming up to your hotel to see you, and now you've got to tell me how things turned out, after you left the theater, or I shall not know just what to do." "About what?" "I'll tell you that, after I hear about last night." Duvall laughed, although a trifle grimly. "I'm not particularly proud of last night," he said. "Wasn't the woman who fainted the one you were after?" asked Grace. "Yes. I'm sure she was. But unfortunately, she got away from me." He outlined to Grace the circumstances which led up to the woman's escape from the cab. "You say she was a small, slight woman, with light hair?" "Yes. Why?" "Then I may know something about her." "What?" "I'll tell you. You remember that, when I came up to see you at the hotel yesterday afternoon, you were greatly put out, because you were afraid that I might have been followed, thus disclosing the name of your hotel to these people you are trying to avoid?" "Yes. I was afraid of it. And the people in question did find out in some way where I had taken Miss Morton and her mother, as I discovered last night." "They did not discover it through me." "How do you know?" "It came about in a curious way. After you told me, over the telephone, that you feared I might have been followed, I looked up the taxi driver who took me uptown, and asked him if anyone had tried to question him. I thought that possibly this hotel might have been watched, and, if so, the person who was watching it might have noticed the number of my car, or the driver, and later, applied to him for information. I saw him as soon as I returned. No one had done so." "That is all very well, but they might have asked him, and found out where he drove you, later." "They did ask him, later. Why is it, Richard, that you seem to forget that I have done detective work before, too? I suspected that he might be approached, and I subsidized him--gave him ten dollars, and instructed him to let me know, in case anyone questioned him about me. "Well, late yesterday afternoon, a woman, answering the description you give, did apply to the cabman to find out where he had driven me. Naturally he told her nothing. Then, thinking, I suppose, that I might repeat my visit, she gave him five dollars, and told him to let her know in case I drove from here to any other hotel. She figured, no doubt, that being your wife, I was certain to go and see you." Duvall sat forward in his chair, an eager look upon his face.
