But how connect her with the murder? It seemed easy enough to do so if this other woman was her rival. We have heard of no rival, but she may have known of one, and this knowledge may have been at the bottom of her disagreement with her husband and the half-crazy determination she evinced to win his family over to her side. Let us say, then, that the second woman was Mrs. Van Burnam's rival. That he brought her there not knowing that his wife had effected an entrance into the house; brought her there after an afternoon spent at the Hotel D----, during which he had furnished her with a new outfit of less pronounced type, perhaps, than that she had previously worn. The use of the two carriages and the care they took to throw suspicion off their track, may have been part of a scheme of future elopement, for I had no idea they meant to remain in Mr. Van Burnam's house. For what purpose, then, did they go there? To meet Mrs. Van Burnam and kill her, that their way might be clearer for flight? No; I had rather think that they went to the house without a thought of whom they would encounter, and that only after they had entered the parlors did he realize that the two women he least wished to see together had been brought by his folly face to face. The presence in the third room of Mrs. Van Burnam's hat, gloves, and novel seemed to argue that she had spent the evening in reading by the dining-room table, but whether this was so or not, the stopping of a carriage in front and the opening of the door by an accustomed hand undoubtedly assured her that either the old gentleman or some other member of the family had unexpectedly arrived. She was, therefore, in or near the parlor-door when they entered, and the shock of meeting her hated rival in company with her husband, under the very roof where she had hoped to lay the foundations of her future happiness, must have been great, if not maddening. Accusations, recriminations even, did not satisfy her. She wanted to kill; but she had no weapon. Suddenly her eyes fell on the hat-pin which her more self-possessed rival had drawn from her hat, possibly before their encounter, and she conceived a plan which seemed to promise her the very revenge she sought. How she carried it out; by what means she was enabled to approach her victim and inflict with such certainty the fatal stab which laid her enemy at her feet, can be left to the imagination. But that she, a woman, and not Howard, a man, drove this woman's weapon into the stranger's spine, I will yet prove, or lose all faith in my own intuitions.
