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?"

“ ‘Milano.’ ‘Lucerne.’ These are from Italy.”

“They are poor Douglas’s things.”

“You have not unpacked them? How long have you had them?”

“They arrived last week.”

“But you said — why, surely this might be the missing link. How do we know that there is not something of value there?”

“There could not possibly be, Mr. Holmes. Poor Douglas had only his pay and a small annuity. What could he have of value?”

Holmes was lost in thought.

“Delay no longer, Mrs. Maberley,” he said at last. “Have these things taken upstairs to your bedroom. Examine them as soon as possible and see what they contain. I will come tomorrow and hear your report.”

It was quite evident that The Three Gables was under very close surveillance, for as we came round the high hedge at the end of the lane there was the negro prize-fighter standing in the shadow. We came on him quite suddenly, and a grim and menacing figure he looked in that lonely place. Holmes clapped his hand to his pocket.

“Lookin’ for your gun, Masser Holmes?”

“No, for my scent-bottle, Steve.”

“You are funny, Masser Holmes, ain’t you?”

“It won’t be funny for you, Steve, if I get after you. I gave you fair warning this morning.”

“Well, Masser Holmes, I done gone think over what you said, and I don’t want no more talk about that affair of Masser Perkins. S’pose I can help you, Masser Holmes, I will.”

“Well, then, tell me who is behind you on this job.”

“So help me the Lord! Masser Holmes, I told you the truth before. I don’t know. My boss Barney gives me orders and that‘s all.”

“Well, just bear in mind, Steve, that the lady in that house, and everything under that roof, is under my protection. Don’t forget it.”

“All right, Masser Holmes. I’ll remember.”

“I’ve got him thoroughly frightened for his own skin, Watson,” Holmes remarked as we walked on. “I think he would double-cross his employer if he knew who he was. It was lucky I had some knowledge of the Spencer John crowd, and that Steve was one of them. Now, Watson, this is a case for Langdale Pike, and I am going to see him now. When I get back I may be clearer in the matter.”

I saw no more of Holmes during the day, but I could well imagine how he spent it, for Langdale Pike was his human book of reference upon all matters of social scandal. This strange, languid creature spent his waking hours in the bow window of a St. James’s Street club and was the receivingstation as well as the transmitter for all the gossip of the metropolis. He made, it was said, a four-figure income by the paragraphs which he contributed every week to the garbage papers which cater to an inquisitive public. If ever, far down in the turbid depths of London life, there was some strange swirl or eddy, it was marked with automatic exactness by this human dial upon the surface. Holmes discreetly helped Langdale to knowledge, and on occasion was helped in turn.
