"They are now in town--Mrs. and Miss Bellin in Swansea Square, and Felix at his chambers in Jermyn Street." "I wonder if Felix is still in communication with Rose Strent?" queried Merrick, half to himself. "It's not impossible! Whatever Rose Strent was or is, she is not a waiting maid. I believe some guilty bond unites the pair, and that Rose assisted Felix in his scoundrelly schemes out of pure love." "Hardly," responded Merrick thoughtfully. "If Rose loved Felix, she would not assist him to marry Olivia, and by removing Francis she certainly did so." "How would it do to see Felix at his chambers and bully him into confession?" "You won't manage that--the man is too clever." "He can't do much against the proofs in my possession." "He'll deny anything!" "At all events I'll try, Merrick. This evening I'll call on Felix and swear that I am going to have him arrested for the murder of his brother. That will bring him to his knees." "It might and it might not. Better look for Rose Strent." "If anyone knows where she is to be found, it is Felix. I can't do better than see him." "Try it, by all means," said the doctor doubtfully, "but I'm afraid you won't get much satisfaction out of him. First find Rose Strent, have the pool dragged and the body found; then, what with the evidence of Fundy and that arrowhead, you will have no difficulty in getting a warrant for his arrest. At present Felix will simply order you out of his rooms." "I'll run the risk of that," I answered, and shortly afterward took my departure. I could not now complain of lack of interest in my life. It took me all my time to keep the many details of this case in mind. There was no doubt that I had already solved the mystery and that Felix was guilty of his brother's death. Yet, as Merrick said, it would be necessary to find the body and thus establish conclusive proof of the crime before the murderer could be convicted. When this was done, the evidence in hand would be sufficient to insure his condemnation. For my part I believed that he would be driven into a corner and forced to confess his complicity in the crime. Firmly convinced of this man's guilt, I was determined he should not marry Olivia. The crime had been committed for her sake, and, seeing that he had behaved in so cowardly a fashion, it was a fit retribution that he should not achieve his purpose. It was no use my warning Olivia as to the true character of Felix, as she firmly believed him to be Francis, and would decline to believe my story. Under these circumstances I judged it advisable to see Felix at his chambers, and warn him that I knew all. Terrified by the predicament in which he found himself, he might leave England, and thus Olivia would be saved from lifelong misery. His punishment for the crime would occur later on; as, notwithstanding his flight, he could be arrested on the Continent while extradition treaties were in force.
