Now it was not easy to measure the importance of a conclusion like this. For whilst there would have been nothing peculiar in this solitary woman, with the few thousands in the bank, boasting of her power to separate her nephew from the lady of his choice, there was every thing that was significant in her using the same language in regard to Miss Dare and Mr. Orcutt. Nothing but the existence of some unsuspected bond between herself and the great lawyer could have accounted, first, for her feeling on the subject of his marriage; and, secondly, for the threat of interference contained in her very emphatic words,--a bond which, while evidently not that of love, was still of a nature to give her control over his destiny, and make her, in spite of her lonely condition, the selfish and determined arbitrator of his fate. What was that bond? A secret shared between them? The knowledge on her part of some fact in Mr. Orcutt's past life, which, if revealed, might serve as an impediment to his marriage? In consideration that the great mystery to be solved was what motive Mr. Orcutt could have had for killing this woman, an answer to this question was manifestly of the first importance. But before proceeding to take any measures to insure one, Mr. Gryce sat down and seriously asked himself whether there was any known fact, circumstantial or otherwise, which refused to fit into the theory that Mr. Orcutt actually committed this crime with his own hand, and at the time he was seen to cross the street and enter Mrs. Clemmens' house. For, whereas the most complete chain of circumstantial evidence does not necessarily prove the suspected party to be guilty of a crime, the least break in it is fatal to his conviction. And Mr. Gryce wished to be as fair to the memory of Mr. Orcutt as he would have been to the living man.
