"Arsène Lupin will be pleased to consider all propositions

       submitted to him through his agents."

      "And that is how crime is always punished and virtue rewarded," said Arsène Lupin, after he had told me the foregoing history of the black pearl.

      "And that is how you, under the assumed name of Grimaudan, ex-inspector of detectives, were chosen by fate to deprive the criminal of the benefit of his crime."

      "Exactly. And I confess that the affair gives me infinite satisfaction and pride. The forty minutes that I passed in the apartment of the Countess d'Andillot, after learning of her death, were the most thrilling and absorbing moments of my life. In those forty minutes, involved as I was in a most dangerous plight, I calmly studied the scene of the murder and reached the conclusion that the crime must have been committed by one of the house servants. I also decided that, in order to get the pearl, that servant must be arrested, and so I left the wainscoat button; it was necessary, also, for me to hold some convincing evidence of his guilt, so I carried away the knife which I found upon the floor, and the key which I found in the lock. I closed and locked the door, and erased the finger-marks from the plaster in the wardrobe-closet. In my opinion, that was one of those flashes—"

      "Of genius," I said, interrupting.

      "Of genius, if you wish. But, I flatter myself, it would not have occurred to the average mortal. To frame, instantly, the two elements of the problem—an arrest and an acquittal; to make use of the formidable machinery of the law to crush and humble my victim, and reduce him to a condition in which, when free, he would be certain to fall into the trap I was laying for him!"

      "Poor devil—"

      "Poor devil, do you say? Victor Danègre, the assassin! He might have descended to the lowest depths of vice and crime, if he had retained the black pearl. Now, he lives! Think of that: Victor Danègre is alive!"

      "And you have the black pearl."

      He took it out of one of the secret pockets of his wallet, examined it, gazed at it tenderly, and caressed it with loving fingers, and sighed, as he said:

      "What cold Russian prince, what vain and foolish rajah may some day possess this priceless treasure! Or, perhaps, some American millionaire is destined to become the owner of this morsel of exquisite beauty that once adorned the fair bosom of Leontine Zalti, the Countess d'Andillot."

IX. Herlock Sholmes Arrives Too Late

       Table of Contents

      "It is really remarkable, Velmont, what a close resemblance you bear to Arsène Lupin!"

      "How do you know?"

      "Oh! like everyone else, from photographs, no two of which are alike, but each of them leaves the impression of a face.... something like yours."

      Horace Velmont displayed some vexation.

      "Quite so, my dear Devanne. And, believe me, you are not the first one who has noticed it."

      "It is so striking," persisted Devanne, "that if you had not been recommended to me by my cousin d'Estevan, and if you were not the celebrated artist whose beautiful marine views I so admire, I have no doubt I should have warned the police of your presence in Dieppe."

      This sally was greeted with an outburst of laughter. The large dining-hall of the Château de Thibermesnil contained on this occasion, besides Velmont, the following guests: Father Gélis, the parish priest, and a dozen officers whose regiments were quartered in the vicinity and who had accepted the invitation of the banker Georges Devanne and his mother. One of the officers then remarked:

      "I understand that an exact description of Arsène Lupin has been furnished to all the police along this coast since his daring exploit on the Paris-Havre express."

      "I suppose so," said Devanne. "That was three months ago; and a week later, I made the acquaintance of our friend Velmont at the casino, and, since then, he has honored me with several visits—an agreeable preamble to a more serious visit that he will pay me one of these days—or, rather, one of these nights."

      This speech evoked another round of laughter, and the guests then passed into the ancient "Hall of the Guards," a vast room with a high ceiling, which occupied the entire lower part of the Tour Guillaume—William's Tower—and wherein Georges Devanne had collected the incomparable treasures which the lords of Thibermesnil had accumulated through many centuries. It contained ancient chests, credences, andirons and chandeliers. The stone walls were overhung with magnificent tapestries. The deep embrasures of the four windows were furnished with benches, and the Gothic windows were composed of small panes of colored glass set in a leaden frame. Between the door and the window to the left stood an immense bookcase of Renaissance style, on the pediment of which, in letters of gold, was the world "Thibermesnil," and, below it, the proud family device: "Fais ce que veulx" (Do what thou wishest). When the guests had lighted their cigars, Devanne resumed the conversation.

      "And remember, Velmont, you have no time to lose; in fact, to-night is the last chance you will have."

      "How so?" asked the painter, who appeared to regard the affair as a joke. Devanne was about to reply, when his mother mentioned to him to keep silent, but the excitement of the occasion and a desire to interest his guests urged him to speak.

      "Bah!" he murmured. "I can tell it now. It won't do any harm."

      The guests drew closer, and he commenced to speak with the satisfied air of a man who has an important announcement to make.

      "To-morrow afternoon at four o'clock, Herlock Sholmes, the famous English detective, for whom such a thing as mystery does not exist; Herlock Sholmes, the most remarkable solver of enigmas the world has ever known, that marvelous man who would seem to be the creation of a romantic novelist—Herlock Sholmes will be my guest!"

      Immediately, Devanne was the target of numerous eager questions. "Is Herlock Sholmes really coming?" "Is it so serious as that?" "Is Arsène Lupin really in this neighborhood?"

      "Arsène Lupin and his band are not far away. Besides the robbery of the Baron Cahorn, he is credited with the thefts at Montigny, Gruchet and Crasville."

      "Has he sent you a warning, as he did to Baron Cahorn?"

      "No," replied Devanne, "he can't work the same trick twice."

      "What then?"

      "I will show you."

      He rose, and pointing to a small empty space between the two enormous folios on one of the shelves of the bookcase, he said:

      "There used to be a book there—a book of the sixteenth century entitled `Chronique de Thibermesnil,' which contained the history of the castle since its construction by Duke Rollo on the site of a former feudal fortress. There were three engraved plates in the book; one of which was a general view of the whole estate; another, the plan of the buildings; and the third—I call your attention to it, particularly—the third was the sketch of a subterranean passage, an entrance to which is outside the first line of ramparts, while the other end of the passage is here, in this very room. Well, that book disappeared a month ago."

      "The deuce!" said Velmont, "that looks bad. But it doesn't seem to be a sufficient reason for sending for Herlock Sholmes."

      "Certainly, that was not sufficient in itself, but another incident happened that gives the disappearance of the book a special significance. There was another copy of this book in the National Library at Paris, and the two books differed in certain details relating to the subterranean passage; for instance, each of them contained drawings and annotations, not printed, but written in ink and more or less effaced. I knew those facts, and I knew that the exact location of the passage could be determined only by a comparison of the two books. Now, the day after my book disappeared, the book was called for in the National Library
