“The Baron has little waxed tips of hair under his nose, like the short antennae of an insect. These quivered with amusement as he listened, and he finally broke into a gentle chuckle.

“ ‘Excuse my amusement, Mr. Holmes,’ said he, ‘but it is really funny to see you trying to play a hand with no cards in it. I don’t think anyone could do it better, but it is rather pathetic all the same. Not a colour card there, Mr. Holmes, nothing but the smallest of the small.’

“ ‘So you think.’

“ ‘So I know. Let me make the thing clear to you, for my own hand is so strong that I can afford to show it. I have been fortunate enough to win the entire affection of this lady. This was given to me in spite of the fact that I told her very clearly of all the unhappy incidents in my past life. I also told her that certain wicked and designing persons — I hope you recognize yourself — would come to her and tell her these things, and I warned her how to treat them. You have heard of post-hypnotic suggestion. Mr. Holmes ‘ Well you will see how it works for a man of personality can use hypnotism without any vulgar passes or tomfoolery. So she is ready for you and, I have no doubt, would give you an appointment, appointment for she is quite amenable to her father’s will — save only in the one little matter.’

“Well, Watson, there seemed to be no more to say, so I took my leave with as much cold dignity as I could summon, but, as I had my hand on the door-handle, he stopped me.

“ ‘By the way, Mr. Holmes,’ said he, ‘did you know Le Brun, the French agent?’

“ ‘Yes,’ said I.

“ ‘Do you know what befell him?’

“‘I heard that he was beaten by some Apaches in the Montmartre district and crippled for life.’

“ ‘Quite true, Mr. Holmes. By a curious coincidence he had been inquiring into my affairs only a week before. Don’t do it, Mr. Holmes; it’s not a lucky thing to do. Several have found that out. My last word to you is, go your own way and let me go mine. Good-bye!’

“So there you are, Watson. You are up to date now.”

“The fellow seems dangerous.”

“Mighty dangerous. I disregard the blusterer, but this is the sort of man who says rather less than he means.”

“Must you interfere? Does it really matter if he marries the girl?”

“Considering that he undoubtedly murdered his last wife, I should say it mattered very much. Besides, the client! Well, well, we need not discuss that. When you have finished your coffee you had best come home with me, for the blithe Shinwell will be there with his report.”

We found him sure enough, a huge, coarse, red-faced, scorbutic man, with a pair of vivid black eyes which were the only external sign of the very cunning mind within. It seems that he had dived down into what was peculiarly his kingdom, and beside him on the settee was a brand which he had brought up in the shape of a slim, flame-like young woman with a pale, intense face, youthful, and yet so worn with sin and sorrow that one read the terrible years which had left their leprous mark upon her.

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."
