The Englishman was delighted. His forecast was verified; he had penetrated to the very heart of the mystery, and found Arsène Lupin to be the moving spirit in it.
Clotilde had not yet displayed any knowledge of his presence, although it was quite improbable that any movement of the intruder had escaped her notice. Lupin had almost reached the door and, in fact, his hand was already seeking the doorknob, when his coat brushed against a small table and knocked something to the floor. Monsieur Destange awoke with a start. Arsène Lupin was already standing in front of him, hat in hand, smiling.
“Maxime Bermond,” exclaimed Mon. Destange, joyfully. “My dear Maxime, what lucky chance brings you here?”
“The wish to see you and Mademoiselle Destange.”
“When did you return from your journey?”
“Yesterday.”
“You must stay to dinner.”
“No, thank you, I am sorry, but I have an appointment to dine with some friends at a restaurant.”
“Come, tomorrow, then, Clotilde, you must urge him to come tomorrow. Ah! my dear Maxime. … I thought of you many times during your absence.”
“Really?”
“Yes, I went through all my old papers in that cupboard, and found our last statement of account.”
“What account?”
“Relating to the avenue Henri-Martin.”
“Ah! do you keep such papers? What for?”
Then the three of them left the room, and continued their conversation in a small parlor which adjoined the library.
“Is it Lupin?” Sholmes asked himself, in a sudden access of doubt. Certainly, from all appearances, it was he; and yet it was also someone else who resembled Arsène Lupin in certain respects, and who still maintained his own individuality, features, and color of hair. Sholmes could hear Lupin’s voice in the adjoining room. He was relating some stories at which Mon. Destange laughed heartily, and which even brought a smile to the lips of the melancholy Clotilde. And each of those smiles appeared to be the reward which Arsène Lupin was seeking, and which he was delighted to have secured. His success caused him to redouble his efforts and, insensibly, at the sound of that clear and happy voice, Clotilde’s face brightened and lost that cold and listless expression which usually pervaded it.
“They love each other,” thought Sholmes, “but what the deuce can there be in common between Clotilde Destange and Maxime Bermond? Does she know that Maxime is none other than Arsène Lupin?”
Until seven o’clock Sholmes was an anxious listener, seeking to profit by the conversation. Then, with infinite precaution, he descended from the gallery, crept along the side of the room to the door in such a manner that the people in the adjoining room did not see him.
When he reached the street Sholmes satisfied himself that there was neither an automobile nor a cab waiting there; then he slowly limped along the boulevard Malesherbes. He turned into an adjacent street, donned the overcoat which he had carried on his arm, altered the shape of his hat, assumed an upright carriage, and, thus transformed, returned to a place whence he could watch the door of Mon. Destange’s house.
In a few minutes Arsène Lupin came out, and proceeded to walk toward the center of Paris by way of the rues de Constantinople and London. Herlock Sholmes followed at a distance of a hundred paces.
Exciting moments for the Englishman! He sniffed the air, eagerly, like a hound following a fresh scent. It seemed to him a delightful thing thus to follow his adversary. It was no longer Herlock Sholmes who was being watched, but Arsène Lupin, the invisible Arsène Lupin. He held him, so to speak, within the grasp of his eye, by an imperceptible bond that nothing could break. And he was pleased to think that the quarry belonged to him.
But he soon observed a suspicious circumstance. In the intervening space between him and Arsène Lupin he noticed several people traveling in the same direction, particularly two husky fellows in slouch hats on the left side of the street, and two others on the right wearing caps and smoking cigarettes. Of course, their presence in that vicinity may have been the result of chance, but Sholmes was more astonished when he observed that the four men stopped when Lupin entered a tobacco shop; and still more surprised when the four men started again after Lupin emerged from the shop, each keeping to his own side of the street.
“Curse it!” muttered Sholmes; “he is being followed.”
He was annoyed at the idea that others were on the trail of Arsène Lupin; that someone might deprive him, not of the glory—he cared little for that—but of the immense pleasure of capturing, single-handed, the most formidable enemy he had ever met. And he felt that he was not mistaken; the men presented to Sholmes’ experienced eye the appearance and manner of those who, while regulating their gait to that of another, wish to present a careless and natural air.
“Is this some of Ganimard’s work?” muttered Sholmes. “Is he playing me false?”
He felt inclined to speak to one of the men with a view of acting in concert with him; but as they were now approaching the boulevard the crowd was becoming denser, and he was afraid he might lose sight of Lupin. So he quickened his pace and turned into the boulevard just in time to see Lupin ascending the steps of the Hungarian restaurant at the corner of the rue du Helder. The door of the restaurant was open, so that Sholmes, while sitting on a bench on the other side of the boulevard, could see Lupin take a seat at a table, luxuriously appointed and decorated with flowers, at which three gentlemen
