A NEW SHERLOCK HOLMES STORY
by

ILLUSTRATED BY A. GILBERT R O I
The three leading figures in this Adventure are Neil Gibson, a famous gold-mining magnate, his wife, and their children's young governess, the attractive Miss Dunbar. The wife was found in the grounds of Thor Place, nearly half a mile from the house, late at night, clad in her dinner dress, with a revolver bullet through her brain. No weapon was found near her. There was no trace of a struggle, but in her loft hand was clutched a note reading: "I will be at Thor Bridge at nine o'clock.—G. Dunbar." Later, the police discovered on the floor of the wardrobe in the governess's room a revolver with one discharged chamber and a calibre which corresponded with the bullet. Miss Dunbar, when arrested, could prove no alibi—on the contrary. she admitted she was near Thor Bridge, the scene of the tragedy, about the time of Mrs. Gibson's death. She also admitted writing the note, but would say no more.
Gibson urges Sherlock Holmes to spare neither trouble nor expense to clear Miss Dunbar. "It's very black against her," he admits. "I can't deny that. . . . And there is no doubt that my wife was bitterly jealous."
The revolver is found to belong to Gibson, but there is no evidence that he had been out of doors, since his return from town at five o'clock. Miss Dunbar, on the other hand, admitted making the appointment with Mrs. Gibson.
On viewing the scene of the tragedy, Sherlock Holmes's careful examination of the bridge reveals a small and apparently recently-made chip on the parapet. "It took some violence to do that," said Holmes, thoughtfully. "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."
As the following instalment shows, this apparently insignificant chip in the stone was really the clue to the solution of the mystery.
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 defence, 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 that 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 this 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 colour 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."
"She poured her whole wild fury out in burning and horrible words—
"My dear young lady," cried Holmes, earnestly, "I beg you to have no illusions upon the point. Mr. Cummings here would assure you that all the cards are at present against us, and that we must do everything that is possible if we are to win clear. It would be a cruel deception to pretend that you are not in very great danger. Give me all the help you can, then, to get at the truth."
"I will conceal nothing."
"Tell us, then, of your true relations with Mr. Gibson"s wife."
"She hated me, Mr. Holmes. She hated me with all the fervour of her tropical nature. She was a woman who would do nothing by halves, and the measure of her love for her husband was the measure also of her hatred for me. It is probable that she misunderstood our relations. I would not wish to wrong her, but she loved so vividly in a physical sense that she could hardly understand the mental, and even spiritual, tie which held her husband to me, or imagine that it was only my desire to influence his power to good ends which kept me under his roof. I can see now that I was wrong. Nothing could justify me in remaining where I was a cause of unhappiness, and yet it is certain that the unhappiness would have remained even if I had left the house."
"Now, Miss Dunbar," said Holmes, "I beg you to tell us exactly what occurred that evening."
"I can tell you the truth so far as I know it, Mr. Holmes, but I am in a position to prove nothing, and there are points—the most vital points—which I can neither explain nor can I imagine any explanation."
"If you will find the facts, perhaps others may find the explanation."
"With regard, then, to my presence at Thor Bridge that night, I received a note from Mrs. Gibson in the morning. It lay on ​the table of the schoolroom, and it may have been left there by her own hand. It implored me to see her there after dinner, said she had something important to say to me, and asked me to leave an answer on the sundial in the garden, as she desired no one to be in our confidence. I saw no reason for such secrecy, but I did as she asked, accepting the appointment. She asked me to destroy her note and I burned it in the schoolroom grate. She was very much afraid of her husband, who treated her with a harshness for which I frequently reproached him, and I could only imagine that she acted in this way because she did not wish him to know of our interview." —I put my hands to my ears and rushed away."
"Yet she kept your reply very carefully?"
"Yes. I was surprised to hear that she had it in her hand when she died."
"Well, what happened then?"
"I went down as I had promised. When I reached the bridge she was waiting for me. Never did I realize till that moment how this poor creature hated me. She was like a mad woman—indeed, I think she was a mad woman, subtly mad with the deep power of deception which insane people may have. How else could she have met me with unconcern every day and yet had so raging a hatred of me in her heart? I will not say what she said. She poured her whole wild fury out in burning and horrible words. I did not even answer—I could not. It was dreadful to see her. I put my hands to my ears and rushed away. When I left her she was standing still shrieking out her curses at me, in the mouth of the bridge."
"Where she was afterwards found?"
"Within a few yards from the spot."
"And yet, presuming that she met her death shortly after you left her, you heard no shot?"
"No, I heard nothing. But, indeed, Mr. Holmes, I was so agitated and horrified by ​this terrible outbreak that I rushed to get back to the peace of my own room, and I was incapable of noticing anything which happened."
"You say that you returned to your room. Did you leave it again before next morning?"
"Yes, when the alarm came that the poor creature had met her death I ran out with the others."
"Did you see Mr. Gibson?"
"Yes, he had just returned from the bridge when I saw him. He had sent for the doctor and the police."
"Did he seem to you much perturbed?"
"Mr. Gibson is a very strong, self-contained man. I do not think that he would ever show his emotions on the surface. But I, who knew him so well, could see that he was deeply concerned."
"Then we come to the all-important point. This pistol that was found in your room. Had you ever seen it before?"
"Never, I swear it."
"When was it found?"
"Next morning, when the police made their search."
"Among your clothes?"
"Yes, on the floor of my wardrobe under my dresses."
"You could not guess how long it had been there?"
"It had not been there the morning before."
"How do you know?"
"Because I tidied out the wardrobe."
"That is final. Then someone came into your room and placed the pistol there in order to inculpate you."
"It must have been so."
"And when?"
"It could only have been at meal-time, or else at the hours when I would be in the schoolroom with the children."
"As you were when you got the note?"
"Yes, from that time onwards for the whole morning."
"Thank you, Miss Dunbar. Is there any other point which could help me in the investigation?"
"I can think of none."
"There was some sign of violence on the stonework of the bridge—a perfectly fresh chip just opposite the body. Could you suggest any possible explanation of that?"
"Surely it must be a mere coincidence."
"Curious, Miss Dunbar, very curious. Why should it appear at the very time of the tragedy and why at the very place?"
"But what could have caused it? Only great violence could have such an effect."
Holmes did not answer. His pale, eager face had suddenly assumed that tense, far-away expression which I had learned to associate with the supreme manifestations of his genius. So evident was the crisis in his mind that none of us dared to speak, and we sat, barrister, prisoner, and myself, watching him in a concentrated and absorbed silence. Suddenly he sprang from his chair, vibrating with nervous energy and the pressing need for action.
"Come, Watson, come!" he cried.
"What is it, Mr. Holmes?"
"Never mind, my dear lady. You will hear from me, Mr. Cummings. With the help of the God of justice I will give you a case which will make England ring. You will get news by tomorrow, Miss Dunbar, and meanwhile take my assurance that the clouds are lifting and that I have every hope that the light of truth is breaking through."
It was not a long journey from Winchester to Thor Place, but it was long to me in my impatience, while for Holmes it was evident that it seemed endless, for, in his nervous restlessness, he could not sit still, but paced the carriage or drummed with his long, sensitive fingers upon the cushions beside him.
Suddenly, however, as we neared our destination he seated himself opposite to me—we had a first-class carriage to ourselves—and laying a hand upon each of my knees he looked into my eyes with the peculiarly mischievous gaze which was characteristic of his more imp-like moods.
"Watson," said he, "I have some recollection that you go armed upon these excursions of ours."
It was as well for him that I did so, for he took little care for his own safety when his mind was once absorbed by a problem, so that more than once my revolver had been a good friend in need. I reminded him of the fact.
"Yes, yes, I am a little absent-minded in such matters. But have you your revolver on you?"
I produced it from my hip-pocket, a short, handy, but very serviceable little weapon. He undid the catch, shook out the cartridges, and examined it with care.
"It"s heavy—remarkably heavy," said he.
"Yes, it is a solid bit of work."
He mused over it for a minute.
"Do you know, Watson," said he, "I believe your revolver is going to have a very intimate connection with the mystery which we are investigating."
"My dear Holmes, you are joking."
"No, Watson, I am very serious. There is a test before us. If the test comes off, all will be clear. And the test will depend upon the conduct of this little weapon. One cartridge out. Now we will replace the other five and put on the safety-catch. So! That increases the weight and makes it a better reproduction."
​ "Suddenly Holmes sprang from his chair. 'Come, Watson, come!' he said. 'With the help of the God of justice I will give you a case which will make England ring.'" ​I had no glimmer of what was in his mind nor did he enlighten me, but sat lost in thought until we pulled up in the little Hampshire station. We secured a ramshackle trap, and in a quarter of an hour were at the house of our confidential friend, the sergeant.
"A clue, Mr. Holmes? What is it?"
"It all depends upon the behaviour of Dr. Watson's revolver," said my friend. "Here it is. Now, officer, can you give me ten yards of string?"
The village shop provided a ball of stout twine.
"I think that this is all we will need," said Holmes. "Now, if you please, we will get off on what I hope is the last stage of our journey."
The sun was setting and turning the rolling Hampshire moor into a wonderful autumnal panorama. The sergeant, with many critical and incredulous glances, which showed his deep doubts of the sanity of my companion, lurched along beside us. As we approached the scene of the crime I could see that my friend under all his habitual coolness was in truth deeply agitated.
"Yes," he said, in answer to my remark, "you have seen me miss my mark before, Watson. I have an instinct for such things, and yet it has sometimes played me false. It seemed a certainty when first it flashed across my mind in the cell at Winchester, but one drawback of an active mind is that one can always conceive alternative explanations which would make our scent a false one. And yet—and yet—Well, Watson, we can but try."
As he walked he had firmly tied one end of the string to the handle of the revolver. We had now reached the scene of the tragedy. With great care he marked out under the guidance of the policeman the exact spot where the body had been stretched. He then hunted among the heather and the ferns until he found a considerable stone. This he secured to the other end of his line of string, and he hung it over the parapet of the bridge so that it swung clear above the water. He then stood on the fatal spot, some distance from the edge of the bridge, with my revolver in his hand, the string being taut between the weapon and the heavy stone on the farther side.
"Now for it!" he cried.
At the words he raised the pistol to his head, and then let go his grip. In an instant it had been whisked away by the weight of the stone, had struck with a sharp crack against the parapet, and had vanished over the side into the water. It had hardly gone before Holmes was kneeling beside the stonework, and a joyous cry showed that he had found what he expected.
"Was there ever a more exact demonstration?" he cried. "See, Watson, your revolver has solved the problem!" As he spoke he pointed to a second chip of the exact size and shape of the first which had appeared on the under edge of the stone balustrade.
"We'll stay at the inn to-night," he continued, as he rose and faced the astonished sergeant. "You will, of course, get a grappling-hook and you will easily restore my friend's revolver. You will also find beside it the revolver, string and weight with which this vindictive woman attempted to disguise her own crime and to fasten a charge of murder upon an innocent victim. You can let Mr. Gibson know that I will see him in the morning, when steps can be taken for Miss Dunbar's vindication."
Late that evening, as we sat together smoking our pipes in the village inn, Holmes gave me a brief review of what had passed.
"I fear, Watson," said he, "that you will not improve any reputation which I may have acquired by adding the Case of the Thor Bridge Mystery to your annals. I have been sluggish in mind and wanting in that mixture of imagination and reality which is the basis of my art. I confess that the chip in the stonework was a sufficient clue to suggest the true solution, and that I blame myself for not having attained it sooner.
"It must be admitted that the workings of this unhappy woman's mind were deep and subtle, so that it was no very simple matter to unravel her plot. I do not think that in our adventures we have ever come across a stranger example of what perverted love can bring about. Whether Miss Dunbar was her rival in a physical or in a merely mental sense seems to have been equally unforgivable in her eyes. No doubt she blamed this innocent lady for all those harsh dealings and unkind words with which her husband tried to repel her too demonstrative affection. Her first resolution was to end her own life. Her second was to do it in such a way as to involve her victim in a fate which was worse far than any sudden death could be.
"We can follow the various steps quite clearly, and they show a remarkable subtlety of mind. A note was extracted very cleverly from Miss Dunbar which would make it appear that she had chosen the scene of the crime. In her anxiety that it should be discovered she somewhat overdid it, by holding it in her hand to the last. This alone should have excited my suspicions earlier than it did.
"Then she took one of her husband's revolvers—there was, as you saw, an arsenal ​in the house—and kept it for her own use. A similar one she concealed that morning in Miss Dunbar's wardrobe after discharging one barrel, which she could easily do in the woods without attracting attention. She then went down to the bridge where she had contrived this exceedingly ingenious method for getting rid of her weapon. When Miss Dunbar appeared she used her last breath in pouring out her hatred, and then, when she was out of hearing, carried out her terrible purpose. Every link is now in its place and the chain is complete. The papers may ask why the mere was not dragged in the first instance, but it is easy to be wise after the event, and in any case the expanse of a reed-filled lake is no easy matter to drag unless you have a clear perception of what you are looking for and where. Well, Watson, we have helped a remarkable woman, and also a formidable man. Should they in the future join their forces, as seems not unlikely, the financial world may find that Mr. Neil Gibson has learned something in that schoolroom of Sorrow where our earthly lessons are taught." "Holmes was kneeling beside the stonework, and a joyous cry showed that he had found what he expected."
