"Being foiled in this his last attempt, this smooth and diabolical villain hesitated no longer in carrying out the scheme which had doubtless been maturing in his mind ever since he dropped the key of his father's house into his own pocket. His brother's wife must die, but not in a hotel room with him for a companion. Though scorned, detested, and a stumbling-block in the way of the whole family's future happiness and prosperity, she still was a Van Burnam, and no shadow must fall upon her reputation. Further than this, for he loved life and his own reputation also, and did not mean to endanger either by this act of self-preservation, she must perish as if from accident, or by some blow so undiscoverable that it would be laid to natural causes. He thought he knew how this might be brought about. He had seen her put on her hat with a very thin and sharp pin, and he had heard how one thrust into a certain spot in the spine would effect death without a struggle. A wound like that would be small; almost indiscernible. True it would take skill to inflict it, and it would require dissimulation to bring her into the proper position for the contemplated thrust; but he was not lacking in either of these characteristics; and so he set himself to the task he had promised himself, and with such success that ere long the two left the hotel and proceeded to the house in Gramercy Park with all the caution necessary for preserving a secret which meant reputation to the one, and liberty, if not life, to the other. That he and not she felt the greater need of secrecy, witness their whole conduct, and when, their goal reached, she and not he put the money into the driver's hand, the last act of this curious drama of opposing motives was reached, and only the final catastrophe was wanting. "With what arts he procured her hat-pin, and by what show of simulated passion he was able to approach near enough to her to inflict that cool and calculating thrust which resulted in her immediate death, I leave to _your_ imagination. Enough that he compassed his ends, killing her and regaining the letter for the possession of which he had been willing to take a life. Afterwards----" "Well, afterwards?"
