The District Attorney stooped, adjusted his glasses and slowly read out:
"C. C. R."
"Carleton Clifton Roberts," explained Mr. Gryce. Then slowly, "The other two if you will be so good."
"E. T."
"Ermentrude Taylor," declared the inexorable voice. "And written by herself. Here is her signature which I have obtained; and here is his. Compare them at your leisure with their initials inscribed according to the date there, sixteen years or more ago. Now where were these two—this man and this woman—at the time just designated? Alone, or together? Let us see if we can find out," pursued the detective with a quiet ignoring of the effect he had produced, which revealed him as the master of a situation probably as difficult and disconcerting as the three officials hanging in manifest anxiety upon his words had ever been called upon to face. "Mr. Roberts was in Switzerland, as his housekeeper will be obliged to admit on oath, she being an honest woman and a domestic in his mother's house at the time. And Ermentrude Taylor! I have a witness to prove where she was also! A witness I should be glad to have you interrogate. Here is her name and address." And he slipped a small scrap of paper into the District Attorney's hand. "What she will say is this, for I think I have very thoroughly sounded her: First, that she is Mrs. Taylor's most intimate friend. This is conceded by all who know her. Secondly, that while her intimacy does not extend back to their girlhood days—Mrs. Taylor being an Englishwoman by birth and remarkably reticent as to her former life and experiences—she has one story to tell of that time which answers the question I have given you. She got it from Mrs. Taylor herself, and in this manner. They were engaged in talking one day about our Western mountains and the grandeur of scenery generally, when Mrs. Taylor let fall some remark about the Alps, which led this friend of hers to ask if she had ever seen them. Mrs. Taylor answered in the affirmative, but with such embarrassment and abrupt change of subject that it was plainly apparent she had no wish to discuss it. Indeed, her abruptness was so marked and her show of trouble so great, she was herself disturbed by what might very easily give offense, and being of a kindly, even loving disposition, took occasion when next they met to explain that it was as a girl she had visited Switzerland, and that her experiences there had been so unfortunate that any allusion which recalled those days distressed her. This is all that ever passed between these two on this subject, but is it not enough when we read this couplet, and mark the combined initials, and recognize them as those of Carleton Roberts and Ermentrude Taylor? But lest you should doubt even this evidence of an old-time friendship so intimate that it has almost the look of a betrothal, I must add one more item of corroborative fact which came to me as late as last night. In a moment of partial consciousness, while the nurse hung over her bed, Mrs. Taylor spoke her first coherent sentence since she fell into a state demanding medical assistance. And what was that sentence? A repetition of this couplet, gentlemen, spoken not once but over and over again, till even the nurse grew tired of listening to it.
As the last word fell from Mr. Gryce's lips, the District Attorney muttered a quick exclamation, and sat down heavily in his chair.
"No coincidence that," he cried, with forced vivacity. "The couplet is too little known."
"Exactly," came from Mr. Gryce in dry confirmation. "Mrs. Taylor, as well as her friends can judge, is a woman of thirty-five or thirty-eight. If she went to Switzerland as a girl, this would make her visit coincident, so far as we can calculate from our present knowledge, with that of Carleton Roberts. For the surer advancement of our argument, let us say that it was. What follows? Let the inscription of this label speak for us. They met; they loved—as was natural when we remember the youth and good looks of both, and—they parted. This we must concede, or how could the experience have been one she could not recall without a heart-break. They parted, and he returned home, to marry within the year, while she—I do not think she married—though I have no doubt she looks upon herself as a wife and forever bound to the man who deserted her. Women of her kind think in this way of such matters, and act upon them too as is shown by the fact that, on following him here, she passed herself off as a woman separated from her husband. Changing the Miss before her name to Mrs., she lived under this assumption for twelve years at her present hotel. In all that time, so far as I can learn, she has never been visited by anyone of an appearance answering to that of her former lover; nor have I any reason to think she ever intruded herself on him, or made herself in any way obnoxious. He was married and settled, and contrary to the usual course of men who step with one stride into affluence, was living a life of usefulness which was rapidly making him a marked man in public esteem. Perhaps she had no right to meddle with what no longer concerned her. At all events, there is no evidence of her having done so in all these fourteen years. Even after Mrs. Roberts' death, all went on as usual; but—" Here Mr. Gryce became emphatic—"when he turned his attention to a second marriage and that with a very young girl—(I can name her to you, gentlemen, if you wish) her patient soul may have been roused; she may have troubled him with importunities; may have threatened him with a scandal which would have interfered greatly with his political hopes if it had not ended them at once. I can conceive such an end to her long patience, can't you, gentlemen? And what is more, if this were so, and the gentleman found the situation intolerable, it might account for the flight of that arrow as nothing else ever will."
Both men had started to their feet.
"How! It was not she——"
"It was not she who was struck, but it was she who was aimed at. The young girl merely got in the way. But before I enlarge upon this point," he continued in lower tones as the two officials slowly reseated themselves, "allow me to admit that any proof of correspondence between these old-time lovers would have added much to my present argument. But while I have no doubt that such an interchange of letters took place, and that in all probability some one or more of them still exist, Mrs. Taylor's illness and Mr. Roberts' high position prevent any substantiation of the same on our part. I must therefore ask you to assume that it was in obedience to some definite agreement between them that she came to the museum on that fatal morning and made her appearance in that especial section of the gallery marked II. If this strikes you as inconceivable and too presumptuous for belief, you must at least concede that we have ample proof of his entire readiness for her coming. The bow brought up so many days before from the cellar was within reach; the arrow under his coat; and his place of concealment so chosen as to make his escape feasible the moment that arrow flew from the bow. Had she entered that section alone—had the arrow found lodgment in her breast instead of in that of another—nay, I will go even further and say that had no cry followed his act, an expectation he had every right to count upon from the lightning-like character of the attack,—he would have reached the Curator's office and been out of the building before quick discovery of the deed made his completion of this attempt impossible."
"But the girl did cry out," remarked the Assistant District Attorney. "How do you account for that, since, as you say, it was not natural for one pierced to the heart without warning?"
