was leaning over the baron, thundering at him with irresistible energy. The baron whispered:
"I'm beginning to understand. It's blackmail…"
"Blackmail or not, call it what you please, my boy, but you've got to go through with it and do as I say. And don't imagine that I shall give way at the last moment. Don't say to yourself, 'Here's a gentleman whom the fear of the police will cause to think twice. If I run a big risk in refusing, he also will be risking the handcuffs, the cells and the rest of it, seeing that we are both being hunted down like wild beasts.' That would be a mistake, monsieur le baron. I can always get out of it. It's a question of yourself, of yourself alone… Your money or your life, my lord! Share and share alike … if not, the scaffold! Is it a bargain?"
A quick movement. The baron released himself, grasped his revolver and fired.
But Lupin was prepared for the attack, the more so as the baron's face had lost its assurance and gradually, under the slow impulse of rage and fear, acquired an expression of almost bestial ferocity that heralded the rebellion so long kept under control.
He fired twice. Lupin first flung himself to one side and then dived at the baron's knees, seized him by both legs and brought him to the ground. The baron freed himself with an effort. The two enemies rolled over in each other's grip; and a stubborn, crafty, brutal, savage struggle followed.
Suddenly, Lupin felt a pain at his chest:
"You villain!" he yelled. "That's your Lavernoux trick; the tie-pin!"
Stiffening his muscles with a desperate effort, he overpowered the baron and clutched him by the throat victorious at last and omnipotent.
"You ass!" he cried. "If you hadn't shown your cards, I might have thrown up the game! You have such a look of the honest man about you! But what a biceps, my lord!.. I thought for a moment… But it's all over, now!.. Come, my friend, hand us the pin and look cheerful… No, that's what I call pulling a face… I'm holding you too tight, perhaps? My lord's at his last gasp?.. Come, be good!.. That's it, just a wee bit of string round the wrists; do you allow me?.. Why, you and I are agreeing like two brothers! It's touching!.. At heart, you know, I'm rather fond of you… And now, my bonnie lad, mind yourself! And a thousand apologies!.."
Half raising himself, with all his strength he caught the other a terrible blow in the pit of the stomach. The baron gave a gurgle and lay stunned and unconscious.
"That comes of having a deficient sense of logic, my friend," said Lupin. "I offered you half your money. Now I'll give you none at all … provided I know where to find any of it. For that's the main thing. Where has the beggar hidden his dust? In the safe? By George, it'll be a tough job! Luckily, I have all the night before me…"
He began to feel in the baron's pockets, came upon a bunch of keys, first made sure that the portmanteau behind the curtain held no papers or jewels, and then went to the safe.
But, at that moment, he stopped short: he heard a noise somewhere. The servants? Impossible. Their attics were on the top floor. He listened. The noise came from below. And, suddenly, he understood: the detectives, who had heard the two shots, were banging at the front door, as was their duty, without waiting for daybreak. Then an electric bell rang, which Lupin recognized as that in the hall:
"By Jupiter!" he said. "Pretty work! Here are these jokers coming … and just as we were about to gather the fruits of our laborious efforts! Tut, tut, Lupin, keep cool! What's expected of you? To open a safe, of which you don't know the secret, in thirty seconds. That's a mere trifle to lose your head about! Come, all you have to do is to discover the secret! How many letters are there in the word? Four?"
He went on thinking, while talking and listening to the noise outside. He double-locked the door of the outer room and then came back to the safe:
"Four ciphers… Four letters … four letters… Who can lend me a hand?.. Who can give me just a tiny hint?.. Who? Why, Lavernoux, of course! That good Lavernoux, seeing that he took the trouble to indulge in optical telegraphy at the risk of his life… Lord, what a fool I am!.. Why, of course, why, of course, that's it!.. By Jove, this is too exciting!.. Lupin, you must count ten and suppress that distracted beating of your heart. If not, it means bad work."
He counted ten and, now quite calm, knelt in front of the safe. He turned the four knobs with careful attention. Next, he examined the bunch of keys, selected one of them, then another, and attempted, in vain, to insert them in the lock:
"There's luck in odd numbers," he muttered, trying a third key. "Victory! This is the right one! Open Sesame, good old Sesame, open!"
The lock turned. The door moved on its hinges. Lupin pulled it to him, after taking out the bunch of keys:
"The millions are ours," he said. "Baron, I forgive you!"
And then he gave a single bound backward, hiccoughing with fright. His legs staggered beneath him. The keys jingled together in his fevered hand with a sinister sound. And, for twenty, for thirty seconds, despite the din that was being raised and the electric bells that kept ringing through the house, he stood there, wild-eyed, gazing at the most horrible, the most abominable sight: a woman's body, half-dressed, bent in two in the safe, crammed in, like an over-large parcel … and fair hair hanging down … and blood … clots of blood … and livid flesh, blue in places, decomposing, flaccid.
"The baroness!" he gasped. "The baroness!.. Oh, the monster!.."
He roused himself from his torpor, suddenly, to spit in the murderer's face and pound him with his heels:
"Take that, you wretch!.. Take that, you villain!.. And, with it, the scaffold, the bran-basket!.."
Meanwhile, shouts came from the upper floors in reply to the detectives' ringing. Lupin heard footsteps scurrying down the stairs. It was time to think of beating a retreat.
In reality, this did not trouble him greatly. During his conversation with the baron, the enemy's extraordinary coolness had given him the feeling that there must be a private outlet. Besides, how could the baron have begun the fight, if he were not sure of escaping the police?
Lupin went into the next room. It looked out on the garden. At the moment when the detectives were entering the house, he flung his legs over the balcony and let himself down by a rain-pipe. He walked round the building. On the opposite side was a wall lined with shrubs. He slipped in between the shrubs and the wall and at once found a little door which he easily opened with one of the keys on the bunch. All that remained for him to do was to walk across a yard and pass through the empty rooms of a lodge; and in a few moments he found himself in the Rue du Faubourg Saint-Honoré. Of course – and this he had reckoned on – the police had not provided for this secret outlet.
"Well, what do you think of Baron Repstein?" cried Lupin, after giving me all the details of that tragic night. "What a dirty scoundrel! And how it teaches one to distrust appearances! I swear to you, the fellow looked a thoroughly honest man!"
"But what about the millions?" I asked. "The princess's jewels?"
"They were in the safe. I remember seeing the parcel."
"Well?"
"They are there still."
"Impossible!"
"They are, upon my word! I might tell you that I was afraid of the detectives, or else plead a sudden attack of delicacy. But the truth is simpler … and more prosaic: the smell was too awful!.."
"What?"
"Yes, my dear fellow, the smell that came from that safe … from that coffin… No, I couldn't do it … my head swam… Another second and I should have been ill… Isn't it silly?.. Look, this is all I got from my expedition: the tie-pin… The bed-rock value of the pearl is thirty thousand francs… But all the same, I feel jolly well annoyed. What a sell!"
"One more question," I said. "The word that opened the safe!"
"Well?"
"How did you guess it?"
"Oh, quite easily! In fact, I am surprised that I didn't think of it sooner."
"Well, tell me."
"It
