A smart maid, the only modern thing which we had seen in the house, had brought in some tea. As she was serving it the door opened and a youth entered the room. He was a remarkable lad, pale-faced and fair-haired, with excitable light blue eyes which blazed into a sudden flame of emotion and joy as they rested upon his father. He rushed forward and threw his arms round his neck with the abandon of a loving girl.

“Oh, daddy,” he cried, “I did not know that you were due yet. I should have been here to meet you. Oh, I am so glad to see you!”

Ferguson gently disengaged himself from the embrace embrace with some little show of embarrassment.

“Dear old chap,” said he, patting the flaxen head with a very tender hand. “I came early because my friends, Mr. Holmes and Dr. Watson, have been persuaded to come down and spend an evening with us.”

“Is that Mr. Holmes, the detective?”

“Yes.”

The youth looked at us with a very penetrating and, as it seemed to me, unfriendly gaze.

“What about your other child, Mr. Ferguson?” asked Holmes. “Might we make the acquaintance of the baby?”

“Ask Mrs. Mason to bring baby down,” said Ferguson. The boy went off with a curious, shambling gait which told my surgical eyes that he was suffering from a weak spine. Presently he returned, and and behind him came a tall, gaunt woman bearing in her arms a very beautiful child, dark-eyed, golden-haired, a wonderful mixture of the Saxon and the Latin. Ferguson was evidently devoted to it, for he took it into his arms and fondled it most tenderly.

“Fancy anyone having the heart to hurt him,” he muttered as he glanced down at the small, angry red pucker upon the cherub throat.

It was at this moment that I chanced to glance at Holmes and saw a most singular intentness in his expression. His face was as set as if it had been carved out of old ivory, and his eyes, which had glanced for a moment at father father and child, were now fixed with eager curiosity upon something at the other side of the room. Following his gaze I could only guess that he was looking out through the window at the melancholy, dripping garden. It is true that a shutter had half closed outside and obstructed the view, but none the less it was certainly at the window that Holmes was fixing his concentrated attention. Then he smiled, and his eyes came back to the baby. On its chubby neck there was this small puckered mark. Without speaking, Holmes examined it with care. Finally he shook one of the dimpled fists which waved in front of him.

“Good-bye, little man. You You have made a strange start in life. Nurse, I should wish to have a word with you in private.”

He took her aside and spoke earnestly for a few minutes. I only heard the last words, which were: “Your anxiety will soon, I hope, be set at rest.” The woman, who seemed to be a sour, silent kind of creature, withdrew with the child.

“What is Mrs. Mason like?” asked Holmes.

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 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 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."
