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 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, and from another pocket, produced his note-case.

Daubrecq took a step forward.

The man opened the pocketbook. 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 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 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?"

He was standing at the open front of a great case which stood between the windows and which contained part of his Chinese collection. He turned as I entered with a small brown vase in his hand.

“Pray sit down, Doctor,” said he. “I was looking over my own treasures and wondering whether I could really afford to add to them. This little Tang specimen, which dates from the seventh century, would probably interest you. I am sure you never saw finer workmanship or a richer glaze. Have you the Ming saucer with you of which you spoke?”

I carefully unpacked it and handed it to him. He seated himself at his desk, pulled over the lamp, for it was growing dark, and set himself to examine it. As he did so the yellow light beat upon his own features, and I was able to study them at my ease.

He was certainly a remarkably handsome man. His European reputation for beauty was fully deserved. In figure he was not more than of middle size, but was built upon graceful and active lines. His face was swarthy, almost Oriental, with large, dark, languorous eyes which might easily hold an irresistible fascination for women. His hair and moustache were raven black, the latter short, pointed, and carefully waxed. His features were regular and pleasing, save only his straight, thin-lipped mouth. If ever I saw a murderer’s mouth it was there — a cruel, hard gash in the face, compressed, inexorable, and terrible. He was ill-advised to train his moustache away from it, for it was Nature’s danger-signal, set as a warning to his victims. His voice was engaging and his manners perfect. In age I should have put him at little over thirty, though his record afterwards showed that he was forty-two.

“Very fine — very fine indeed!” he said at last. “And you say you have a set of six to correspond. What puzzles me is that I should not have heard of such magnificent specimens. I only know of one in England to match this, and it is certainly not likely to be in the market. Would it be indiscreet if I were to ask you, Dr. Hill Barton, how you obtained this?”

“Does it really matter?” I asked with as careless an air as I could muster.

“You can see that the piece is genuine, and, as to the value, I am content to take an expert’s valuation.”

“Very mysterious,” said he with a quick, suspicious flash of his dark eyes. “In dealing with objects of such value, one naturally wishes to know all about the transaction. That the piece is genuine is certain. I have no doubts at all about that. But suppose — I am bound to take every possibility into account — that it should prove afterwards that you had no right to sell?”

“I would guarantee you against any claim of the son.”

“That, of course, would open up the question as to what your guarantee was worth.”

“My bankers would answer that.”

“Quite so. And yet the whole transaction strikes me as rather unusual.”
