"Impossible!" cried the professor. "I swear to you, though...."
"That you have not betrayed me?... I don't doubt it, but the fellows are clever. Look, there's Folenfant!... And Graume!... And Dieuzy!... All my best pals, what?"
Matre Detinan looked at him in surprise. What calmness! He was laughing with a happy laugh, as though he were amusing himself at some child's game, with no danger threatening him.
This carelessness did even more than the sight of the detectives to reassure the lawyer. He moved away from the table on which the bank-notes lay.
Arsne Lupin took up the two bundles one after the other, counted twenty-five notes from each of them and, handing the lawyer the fifty bank-notes thus obtained, said:
"M. Gerbois' share of your fee, my dear matre, and Arsne Lupin's. We owe you that."
"You owe me nothing," said Matre Detinan.
"What! After all the trouble we've given you!"
"You forget the pleasure it has been to me to take that trouble."
"You mean to say, my dear matre, that you refuse to accept anything from Arsne Lupin. That's the worst," he sighed, "of having a bad reputation." He held out the fifty thousand francs to the professor. "Monsieur, let me give you this in memory of our pleasant meeting: it will be my wedding-present to Mlle. Gerbois."
M. Gerbois snatched at the notes, but protested:
"My daughter is not being married."
"She can't be married if you refuse your consent. But she is dying to be married."
"What do you know about it?"
"I know that young ladies often cherish dreams without Papa's consent. Fortunately, there are good geniuses, called Arsne Lupin, who discover the secret of those charming souls hidden away in their writing-desks."
"Did you discover nothing else?" asked Matre Detinan. "I confess that I am very curious to know why that desk was the object of your attentions."
"Historical reasons, my dear matre. Although, contrary to M. Gerbois' opinion, it contained no treasure beyond the lottery-ticket, of which I did not know, I wanted it and had been looking for it for some time. The desk, which is made of yew and mahogany, decorated with acanthus-leaf capitals, was found in Marie Walewska's discreet little house at Boulogne-sur-Seine and has an inscription on one of the drawers: '_Dedicated to Napoleon I., Emperor of the French, by his most faithful servant, Mancion._' Underneath are these words, carved with the point of a knife: '_Thine, Marie._' Napoleon had it copied afterward for the Empress Josephine, so that the writing-desk which people used to admire at the Malmaison and which they still admire at the Garde-Meuble is only an imperfect copy of the one which now forms part of my collection."
M. Gerbois sighed:
"Oh, dear! If I had only known this at the shop, how willingly I would have let you have it!"
Arsne Lupin laughed:
"Yes; and you would, besides, have had the appreciable advantage of keeping the whole of number 514, series 23, for yourself."
"And you would not have thought of kidnapping my daughter, whom all this business must needs have upset."
"All what business?"
"The abduction ..."
"But, my dear sir, you are quite mistaken. Mlle. Gerbois was not abducted."
"My daughter was not abducted!"
"Not at all. Kidnapping, abduction implies violence. Now Mlle. Gerbois acted as a hostage of her own free will."
"Of her own free will!" repeated the professor, in confusion.
"And almost at her own request! Why, a quick-witted young lady like Mlle. Gerbois, who, moreover, harbours a secret passion at the bottom of her heart, was hardly likely to refuse the opportunity of securing her dowry. Oh, I assure you it was easy enough to make her understand that there was no other way of overcoming your resistance!"
Matre Detanin was greatly amused. He put in:
"You must have found a difficulty in coming to terms. I can't believe that Mlle. Gerbois allowed you to speak to her."
"I didn't. I have not even the honour of knowing her. A lady of my acquaintance was good enough to undertake the negotiations."
"The blonde lady in the motor-car, I suppose?" said Matre Detinan.
"Just so. Everything was settled at the first interview near the college. Since then, Mlle. Gerbois and her new friend have been abroad, have visited Belgium and Holland in the most agreeable and instructive manner for a young girl. However, she will tell you everything herself...."
The hall-door bell rang: three rings in quick succession, then a single ring, then another single ring.
"There she is," said Lupin. "My dear matre, if you would not mind...."
The lawyer ran to open the door.
* * * * *
Two young women entered. One of them flung herself into M. Gerbois' arms. The other went up to Lupin. She was tall and shapely, with a very pale face, and her fair hair, which glittered like gold, was parted into two loosely waved bandeaux. Dressed in black, wearing no ornament beyond a five-fold jet necklace, she nevertheless struck a note of elegance and refinement.
Arsne Lupin spoke a few words to her and then, bowing to Mlle. Gerbois, said:
"I must apologize to you, mademoiselle, for all this annoyance; but I hope, nevertheless, that you have not been too unhappy...."
"Unhappy! I should even have been very happy, if it had not been for my poor father."
"Then all is for the best. Embrace him once more and take the opportunity--you will never have a better--of speaking to him about your cousin."
"My cousin?... What do you mean?... I don't understand...."
"Oh, I think you understand.... Your cousin Philippe ... the young man whose letters you kept so preciously...."
Suzanne blushed, lost countenance and then, taking Lupin's advice, threw herself once more into her father's arms.
Lupin looked at them both with a melting eye:
"Ah, we are always rewarded for doing good! What a touching sight! Happy father! Happy daughter! And to think that this happiness is your work, Lupin! Those two beings will bless you later.... Your name will be piously handed down to their children and their children's children.... Oh, family life!... Family life!..." He turned to the window. "Is our dear Ganimard there still?... How he would love to witness this charming display of affection!... But no, he is not there.... There is nobody ... they're all gone.... By Jove, the position is growing serious!... I shouldn't wonder if they were in the gateway by now ... or by the porter's lodge ... or even on the stairs!"
M. Gerbois made an involuntary movement. Now that his daughter was restored to him, he began to see things in their true light. The arrest of his adversary meant half a million to him. Instinctively, he took a step toward the door.... Lupin barred his way, as though by accident:
"Where are you going, M. Gerbois? To defend me against them? You are too kind! Pray don't trouble. Besides, I assure you they are more perplexed than I." And he continued, reflectively: "What do they know, when all is said? That you are here ... and, perhaps, that Mlle. Gerbois is here too, for they must have seen her come with an unknown lady. But they have no idea that
