without stopping at the doctor's door, he continued to the fifth floor. There, he tried two keys. One of them fitted the lock.
"Ah! good!" he murmured, "that simplifies the business wonderfully. But before I commence work I had better arrange for my retreat. Let me see.... have I had sufficient time to rouse the doctor and be dismissed by him? Not yet.... a few minutes more."
At the end of ten minutes, he descended the stairs, grumbling noisily about the doctor. The concierge opened the door for him and heard it click behind him. But the door did not lock, as the man had quickly inserted a piece of iron in the lock in such a manner that the bolt could not enter. Then, quietly, he entered the house again, unknown to the concierge. In case of alarm, his retreat was assured. Noiselessly, he ascended to the fifth floor once more. In the antechamber, by the light of his electric lantern, he placed his hat and overcoat on one of the chairs, took a seat on another, and covered his heavy shoes with felt slippers.
"Ouf! Here I am—and how simple it was! I wonder why more people do not adopt the profitable and pleasant occupation of burglar. With a little care and reflection, it becomes a most delightful profession. Not too quiet and monotonous, of course, as it would then become wearisome."
He unfolded a detailed plan of the apartment.
"Let me commence by locating myself. Here, I see the vestibule in which I am sitting. On the street front, the drawing-room, the boudoir and dining-room. Useless to waste any time there, as it appears that the countess has a deplorable taste.... not a bibelot of any value!...Now, let's get down to business!... Ah! here is a corridor; it must lead to the bed chambers. At a distance of three metres, I should come to the door of the wardrobe-closet which connects with the chamber of the countess." He folded his plan, extinguished his lantern, and proceeded down the corridor, counting his distance, thus:
"One metre.... two metres.... three metres....Here is the door....Mon Dieu, how easy it is! Only a small, simple bolt now separates me from the chamber, and I know that the bolt is located exactly one metre, forty-three centimeters, from the floor. So that, thanks to a small incision I am about to make, I can soon get rid of the bolt."
He drew from his pocket the necessary instruments. Then the following idea occurred to him:
"Suppose, by chance, the door is not bolted. I will try it first."
He turned the knob, and the door opened.
"My brave Lupin, surely fortune favors you....What's to be done now? You know the situation of the rooms; you know the place in which the countess hides the black pearl. Therefore, in order to secure the black pearl, you have simply to be more silent than silence, more invisible than darkness itself."
Arsène Lupin was employed fully a half-hour in opening the second door—a glass door that led to the countess' bedchamber. But he accomplished it with so much skill and precaution, that even had had the countess been awake, she would not have heard the slightest sound. According to the plan of the rooms, that he holds, he has merely to pass around a reclining chair and, beyond that, a small table close to the bed. On the table, there was a box of letter-paper, and the black pearl was concealed in that box. He stooped and crept cautiously over the carpet, following the outlines of the reclining-chair. When he reached the extremity of it, he stopped in order to repress the throbbing of his heart. Although he was not moved by any sense of fear, he found it impossible to overcome the nervous anxiety that one usually feels in the midst of profound silence. That circumstance astonished him, because he had passed through many more solemn moments without the slightest trace of emotion. No danger threatened him. Then why did his heart throb like an alarm-bell? Was it that sleeping woman who affected him? Was it the proximity of another pulsating heart?
He listened, and thought he could discern the rhythmical breathing of a person asleep. It gave him confidence, like the presence of a friend. He sought and found the armchair; then, by slow, cautious movements, advanced toward the table, feeling ahead of him with outstretched arm. His right had touched one of the feet of the table. Ah! now, he had simply to rise, take the pearl, and escape. That was fortunate, as his heart was leaping in his breast like a wild beast, and made so much noise that he feared it would waken the countess. By a powerful effort of the will, he subdued the wild throbbing of his heart, and was about to rise from the floor when his left hand encountered, lying on the floor, an object which he recognized as a candlestick—an overturned candlestick. A moment later, his hand encountered another object: a clock—one of those small traveling clocks, covered with leather. ———-
Well! What had happened? He could not understand. That candlestick, that clock; why were those articles not in their accustomed places? Ah! what had happened in the dread silence of the night?
Suddenly a cry escaped him. He had touched—oh! some strange, unutterable thing! "No! no!" he thought, "it cannot be. It is some fantasy of my excited brain." For twenty seconds, thirty seconds, he remained motionless, terrified, his forehead bathed with perspiration, and his fingers still retained the sensation of that dreadful contact.
Making a desperate effort, he ventured to extend his arm again. Once more, his hand encountered that strange, unutterable thing. He felt it. He must feel it and find out what it is. He found that it was hair, human hair, and a human face; and that face was cold, almost icy.
However frightful the circumstances may be, a man like Arsène Lupin controls himself and commands the situation as soon as he learns what it is. So, Arsène Lupin quickly brought his lantern into use. A woman was lying before him, covered with blood. Her neck and shoulders were covered with gaping wounds. He leaned over her and made a closer examination. She was dead.
"Dead! Dead!" he repeated, with a bewildered air.
He stared at those fixed eyes, that grim mouth, that livid flesh, and that blood—all that blood which had flowed over the carpet and congealed there in thick, black spots. He arose and turned on the electric lights. Then he beheld all the marks of a desperate struggle. The bed was in a state of great disorder. On the floor, the candlestick, and the clock, with the hands pointing to twenty minutes after eleven; then, further away, an overturned chair; and, everywhere, there was blood, spots of blood and pools of blood.
"And the black pearl?" he murmured.
The box of letter-paper was in its place. He opened it, eagerly. The jewel-case was there, but it was empty.
"Fichtre!" he muttered. "You boasted of your good fortune much too soon, my friend Lupin. With the countess lying cold and dead, and the black pearl vanished, the situation is anything but pleasant. Get out of here as soon as you can, or you may get into serious trouble."
Yet, he did not move.
"Get out of here? Yes, of course. Any person would, except Arsène Lupin. He has something better to do. Now, to proceed in an orderly way. At all events, you have a clear conscience. Let us suppose that you are the commissary of police and that you are proceeding to make an inquiry concerning this affair——Yes, but in order to do that, I require a clearer brain. Mine is muddled like a ragout."
He tumbled into an armchair, with his clenched hands pressed against his burning forehead.
The murder of the avenue Hoche is one of those which have recently surprised and puzzled the Parisian public, and, certainly, I should never have mentioned the affair if the veil of mystery had not been removed by Arsène Lupin himself. No one knew the exact truth of the case.
Who did not know—from having met her in the Bois—the fair Léotine Zalti, the once-famous cantatrice, wife and widow of the Count d'Andillot; the Zalti, whose luxury dazzled all Paris some twenty years ago; the Zalti who acquired an European reputation for the magnificence of her diamonds and pearls? It was said that she wore upon her shoulders the capital of several banking houses and the gold mines of numerous Australian companies. Skilful jewelers worked for Zalti as they had formerly wrought for kings and queens. And who does not remember the catastrophe in which all that wealth was swallowed up? Of all that marvelous collection, nothing remained except the famous black pearl. The black pearl! That is to say a fortune, if she had wished to part with it.
But she preferred to keep it, to live in a commonplace apartment with her companion,
