"The problem is certainly a very interesting one. The point of the letter is very obscure, is it not?"
"Well, sir," said the guide, "it seemed, if I may be so bold as to say so, the only really clear point in the whole case."
Holmes shook his head.
"Granting that the letter is genuine and was really written, it was certainly received some time before say one hour or two. Why, then, was this lady still clasping it in her left hand? Why should she carry it so carefully? She did not need to refer to it in the interview. Does it not seem remarkable?"
"Well, sir, as you put it, perhaps it does."
"I think I should like to sit quietly for a few minutes and think it out." He seated himself upon the stone ledge of the bridge, and I could see his quick gray eyes darting their questioning glances in every direction. Suddenly he sprang up again and ran across to the opposite parapet, whipped his lens from his pocket, and began to examine the stonework.
"This is curious," said he.
"Yes, sir, we saw the chip on the ledge. I expect it's been done by some passerby."
The stonework was gray, but at this one point it showed white for a space not larger than a sixpence. When examined closely one could see that the surface was chipped as by a sharp blow.
"It took some violence to do that," said Holmes thoughtfully. With his cane he struck the ledge several times without leaving a mark. "Yes, it was a hard knock. In a curious place, too. It was not from above but from below, for you see that it is on the lower edge of the parapet."
"But it is at least fifteen feet from the body."
"Yes, it is fifteen feet from the body. It may have nothing to do with the matter, but it is a point worth noting. I do not think that we have anything more to learn here. There were no footprints, you say?"
"The ground was iron hard, sir. There were no traces at all."
"Then we can go. We will go up to the house first and look over these weapons of which you speak. Then we shall get on to Winchester, for I should desire to see Miss Dunbar before we go farther."
Mr. Neil Gibson had not returned from town, but we saw in the house the neurotic Mr. Bates who had called upon us in the morning. He showed us with a sinister relish the formidable array of firearms of various shapes and sizes which his employer had accumulated in the course of an adventurous life.
"Mr. Gibson has his enemies, as anyone would expect who knew him and his methods," said he. "He sleeps with a loaded revolver in the drawer beside his bed. He is a man of violence, sir, and there are times when all of us are afraid of him. I am sure that the poor lady who has passed was often terrified."
"Did you ever witness physical violence towards her?"
"No, I cannot say that. But I have heard words which were nearly as bad words of cold, cutting contempt, even before the servants."
"Our millionaire does not seem to shine in private life," remarked Holmes as we made our way to the station. "Well, Watson, we have come on a good many facts, some of them new ones, and yet I seem some way from my conclusion. In spite of the very evident dislike which Mr. Bates has to his employer, I gather from him that when the alarm came he was undoubtedly in his library. Dinner was over at 8:30 and all was normal up to then. It is true that the alarm was somewhat late in the evening, but the tragedy certainly occurred about the hour named in the note. There is no evidence at all that Mr. Gibson had been out of doors since his return from town at five o'clock. On the other hand, Miss Dunbar, as I understand it, admits that she had made an appointment to meet Mrs. Gibson at the bridge. Beyond this she would say nothing, as her lawyer had advised her to reserve her defense We have several very vital questions to ask that young lady, and my mind will not be easy until we have seen her. I must confess that the case would seem to me to be very black against her if it were not for one thing."
"And what is that, Holmes?"
"The finding of the pistol in her wardrobe."
"Dear me, Holmes!" I cried, "that seemed to me to be the most damning incident of all."
"Not so, Watson. It had struck me even at my first perfunctory reading as very strange, and now that I am in closer touch with the case it is my only firm ground for hope. We must look for consistency. Where there is a want of it we must suspect deception."
"I hardly follow you."
"Well now, Watson, suppose for a moment that we visualize you in the character of a woman who, in a cold, premeditated fashion, is about to get rid of a rival. You have planned it. A note has been written. The victim has come. You have your weapon. The crime is done. It has been workmanlike and complete. Do you tell me that after carrying out so crafty a crime you would now ruin your reputation as a criminal by forgetting to fling your weapon into those adjacent reed-beds which would forever cover it, but you must needs carry it carefully home and put it in your own wardrobe, the very first place that would be searched? Your best friends would hardly call you a schemer, Watson, and yet I could not picture you doing anything so crude as that."
"In the excitement of the moment "
"No, no, Watson, I will not admit that it is possible. Where a crime is coolly premeditated, then the means of covering it are coolly premeditated also. I hope, therefore, that we are in the presence of a serious misconception."
"But there is so much to explain."
"Well, we shall set about explaining it. When once your point of view is changed, the very thing which was so damning becomes a clue to the truth. For example, there is this revolver. Miss Dunbar disclaims all knowledge of it. On our new theory she is speaking truth when she says so. Therefore, it was placed in her wardrobe. Who placed it there? Someone who wished to incriminate her. Was not that person the actual criminal? You see how we come at once upon a most fruitful line of inquiry."
We were compelled to spend the night at Winchester, as the formalities had not yet been completed, but next morning, in the company of Mr. Joyce Cummings, the rising barrister who was entrusted with the defense, we were allowed to see the young lady in her cell. I had expected from all that we had heard to see a beautiful woman, but I can never forget the effect which Miss Dunbar produced upon me. It was no wonder that even the masterful millionaire had found in her something more powerful than himself something which could control and guide him. One felt, too, as one looked at the strong, clear-cut, and yet sensitive face, that even should she be capable of some impetuous deed, none the less there was an innate nobility of character which would make her influence always for the good. She was a brunette, tall, with a noble figure and commanding presence, but her dark eyes had in them the appealing, helpless expression of the hunted creature who feels the nets around it, but can see no way out from the toils. Now, as she realized the presence and the help of my famous friend, there came a touch of color in her wan cheeks and a light of hope began to glimmer in the glance which she turned upon us.
"Perhaps Mr. Neil Gibson has told you something of what occurred between us?" she asked in a low, agitated voice.
"Yes," Holmes answered, "you need not pain yourself by entering into that part of the story. After seeing you, I am prepared to accept Mr. Gibson's statement both as to the influence which you had over him and as to the innocence of your relations with him. But why was the whole situation not brought out in court?"
"It seemed to me incredible that such a charge could be sustained. I thought that if we waited the whole thing must clear itself up without our being compelled to enter into painful details of the inner life of the family. But I understand that far from clearing it has become even more serious."
