“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 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 defence. 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.”

Lupin exclaimed:

"What! Did Daubrecq plot the present business?"

"No, no, that is only an accident. The hateful prophecy was just a wish which he expressed. But oh, how it terrified me! I was ailing at the time; my other son, my little Jacques, had just been born. And every day we heard of some fresh misdeed of Gilbert's - forgeries, swindles - so much so that we spread the news, in our immediate surroundings, of his departure for abroad, followed by his death. Life was a misery; and it became still more so when the political storm burst in which my husband was to meet his death."

"What do you mean?"

"A word will be enough: my husband's name was on the list of the Twenty-seven."

"Ah!"

The veil was suddenly lifted from Lupin's eyes and he saw, as in a flash of lightning, a whole legion of things which, until then, had been hidden in the darkness.

Clarisse Mergy continued, in a firmer voice:

"Yes, his name was on it, but by mistake, by a piece of incredible ill-luck of which he was the victim. It is true that Victorien Mergy was a member of the committee appointed to consider the question of the Two-Seas Canal. It is true that he voted with the members who were in favour of the company's scheme. He was even paid - yes, I tell you so plainly and I will mention the sum - he was paid fifteen thousand francs. But he was paid on behalf of another, of one of his political friends, a man in whom he had absolute confidence and of whom he was the blind, unconscious tool. He thought he was showing his friend a kindness; and it proved his own undoing. It was not until the day after the suicide of the chairman of the company and the disappearance of the secretary, the day on which the affair of the canal was published in the papers, with its whole series of swindles and abominations, that my husband knew that a number of his fellow-members had been bribed and learnt that the mysterious list, of which people suddenly began to speak, mentioned his name with theirs and with the names of other deputies, leaders of parties and influential politicians. Oh, what awful days those were! Would the list be published? Would his name come out? The torture of it! You remember the mad excitement in the Chamber, the atmosphere of terror and denunciation that prevailed. Who owned the list? Nobody could say. It was known to be in existence and that was all. Two names were sacrificed to public odium. Two men were swept away by the storm. And it remained unknown where the denunciation came from and in whose hands the incriminating documents were."

"Daubrecq," suggested Lupin.

"No, no!" cried Madame Mergy. "Daubrecq was nothing at that time: he had not yet appeared upon the scene. No, don't you remember, the truth came out suddenly through the very man who was keeping it back: Germineaux, the ex-minister of justice, a cousin of the chairman of the Canal Company. As he lay dying of consumption, he wrote from his sick-bed to the prefect of police, bequeathing him that list of names, which, he said, would be found, after his death, in an iron chest in the corner of his room. The house was surrounded by police and the prefect took up his quarters by the sick man's bedside. Germineaux died. The chest was opened and found to be empty."
