"Some of her sharp practice has come to my knowledge, and she has made a little trouble for one of my friends. I want to know all that I can about her, for it may be necessary to put a stop to her career."

With a renewed expression of his thanks for the information given, Clarence bowed himself out of the old man's presence, with a sense of relief at inhaling the fresh, pure air of the outer world. Then he turned his steps homeward, assured that it had been a good day's work well done.


CHAPTER XXVII.

CLAIRE TURNS CIRCE.

There was more to tell than to learn, when Clarence called, a day or two later, at the villa.

The expert who had been dogging the steps of Lucian Davlin, had made his report, it is true. But that report was a very unsatisfactory affair:

A man, whom Clarence readily identified with the Professor, was an almost constant visitor at the rooms of the Man of Luck, but they, that is, the Professor and Davlin, were never seen on the street together, nor, indeed, anywhere else. In short, Lucian Davlin had been closely shadowed, but with no success to speak of. He came and went just as such a man usually does. And no person that might be made to answer for a doctor, had been visited by him or had visited him unless, and this began to appear possible, the Professor himself was the man.

After a long and serious discussion of the pros and cons of the case, Olive and Clarence decided they would instruct the detective to transfer his attentions to the Professor, only keeping a general surveillance over Davlin. They began to fear that they were watching the wrong man.

Those were pleasant days to Doctor Vaughan; the days when he rode down to the pretty villa to consult with Olive and to look at Claire.
