Daubrecq, laughing, pushed him away repeatedly, but the man clung to him. He behaved aimost like one out of his mind and, at last, in a genuine fit of madness, half rose to his feet, took the deputy by the throat and flung him back in a chair. Daubrecq struggled, powerless at first, while his veins swelled in his temples. But soon, with a strength far beyond the ordinary, he regained the mastery and deprived his adversary of all power of movement. Then, holding him with one hand, with the other he gave him two great smacks in the face.

The man got up, slowly. He was livid and could hardly stand on his his legs. He waited for a moment, as though to recover his self-possession. Then, with a terrifying calmness, he drew a revolver from his pocket and levelled it at Daubrecq.

Daubrecq did not flinch. He even smiled, with a defiant air and without displaying more excitement than if he had been aimed at with a toy pistol.

The man stood for perhaps fifteen or twenty seconds, facing his enemy, with outstretched arm. Then, with the same deliberate slowness, revealing a sell-control which was all the more impressive because it followed upon a fit of extreme excitement, he put up his revolver and, from another pocket, produced his note-case.

Daubrecq took a step forward.

The man opened the pocketbook. A A sheaf of banknotes appeared in sight.

Daubrecq seized and counted them. They were thousand-franc notes, and there were thirty of them.

The man looked on, without a movement of revolt, without a protest. He obviously understood the futility of words. Daubrecq was one of those who do not relent. Why should his visitor waste time in beseeching him or even in revenging himself upon him by uttering vain threats and insults? He had no hope of stricking that unassailable enemy. Even Daubrecq's death would not deliver him from Daubrecq.

He took his hat and went away.

At eleven o'clock in the morning Victoire, on returning from her shopping, handed Lupin a note from his accomplices.

He accomplices opened it and read:

"The man who came to see Daubrecq last night is Langeroux the deputy, leader of the independent left. A poor man, with a large family."

"Come," said Lupin, "Daubrecq is nothing more nor less than a blackmailer; but, by Jupiter, he has jolly effective ways of going to work!"

Events tended to confirm Lupin's supposition. Three days later he saw another visitor hand Daubrecq an important sum of money. And, two days after that, one came and left a pearl necklace behind him.

The first was called Dachaumont, a senator and excabinet-minister. The second was the Marquis d'Albufex, a Bonapartist deputy, formerly chief political agent in France of Prince Napoleon.

The scene, in each each of these cases, was very similar to Langeroux the deputy's interview, a violent tragic scene, ending in Daubrecq's victory.

"And so on and so forth," thought Lupin, when he received these particulars. "I have been present at four visits. I shall know no more if there are ten, or twenty, or thirty... It is enough for me to learn the names of the visitors from my friends on sentry-go outside. Shall I go and call on them?... What for? They have no reason to confide in me... On the other hand, am I to stay on here, delayed by investigations which lead to nothing and which Victoire can continue just as well without me?"

Now for for the point which I will make more plain when we meet. Indeed, this note is merely to give you a general idea of the situation and to ascertain whether you would care to interest yourself in the matter. The lady began to show some curious traits quite alien to her ordinarily sweet and gentle disposition. The gentleman had been married twice and he had one son by the first wife. This boy was now fifteen, a very charming and affectionate youth, though unhappily injured through an accident in childhood. Twice the wife was caught in the act of assaulting this poor lad in the most unprovoked way. Once she struck him with a stick and left a a great weal on his arm.

This was a small matter, however, compared with her conduct to her own child, a dear boy just under one year of age. On one occasion about a month ago this child had been left by its nurse for a few minutes. A loud cry from the baby, as of pain, called the nurse back. As she ran into the room she saw her employer, the lady, leaning over the baby and apparently biting his neck. There was a small wound in the neck from which a stream of blood had escaped. The nurse was so horrified that she wished to call the husband, but the lady implored her not to do so and actually gave her five pounds as a price for her silence. No explanation was ever given, and for the moment the matter was passed over.

It left, however, a terrible impression upon the nurse’s mind, and from that time she began to watch her mistress closely and to keep a closer guard upon the baby, whom she tenderly loved. It seemed to her that even as she watched the mother, so the mother watched her, and that every time she was compelled to leave the baby alone the mother was waiting to get at it. Day and night the nurse covered the child, and day and night the silent, watchful mother seemed to be lying in wait as a wolf waits for a lamb. It must read most incredible to you, and yet I beg you to take it seriously, for a child’s life and a man‘s sanity may depend upon it.

At last there came one dreadful day when the facts could no longer be concealed from the husband. The nurse’s nerve had given way; she could stand the strain no longer, and she made a clean breast of it all to the man. To him it seemed as wild a tale as it may now seem to you. He knew his wife to be a loving wife, and, save for the assaults upon her stepson, a loving mother. Why, then, should she wound her own dear little baby? He told the nurse that she was dreaming, that her suspicions were those of a lunatic, and that such libels upon her mistress were not to be tolerated. While they were talking a sudden cry of pain was heard. Nurse and master rushed together to the nursery.

Imagine his feelings, Mr. Holmes, as he saw his wife rise from a kneeling position beside the cot and saw blood upon the child’s exposed neck and upon the sheet. With a cry of horror, he turned his wife’s face to the light and saw blood all round her lips. It was she — she beyond all question — who had drunk the poor baby’s blood.
