cried the Duke in a sudden shout that made them both jump.
"And a pearl necklace," said Germaine.
"Hurrah!" cried the Duke.
"You're perfectly childish," said Germaine pettishly. "I tell you we've been given a paper-knife, and you shout 'hurrah!' I say we've been given a pearl necklace, and you shout 'hurrah!' You can't have the slightest sense of values."
"I beg your pardon. This pearl necklace is from one of your father's friends, isn't it?" said the Duke.
"Yes; why?" said Germaine.
"But the inkstand and the paper-knife must be from the Faubourg Saint-Germain, and well on the shabby side?" said the Duke.
"Yes; well?"
"Well then, my dear girl, what are you complaining about? They balance; the equilibrium is restored. You can't have everything," said the Duke; and he laughed mischievously.
Germaine flushed, and bit her lip; her eyes sparkled.
"You don't care a rap about me," she said stormily.
"But I find you adorable," said the Duke.
"You keep annoying me," said Germaine pettishly. "And you do it on purpose. I think it's in very bad taste. I shall end by taking a dislike to you—I know I shall."
"Wait till we're married for that, my dear girl," said the Duke; and he laughed again, with a blithe, boyish cheerfulness, which deepened the angry flush in Germaine's cheeks.
"Can't you be serious about anything?" she cried.
"I am the most serious man in Europe," said the Duke.
Germaine went to the window and stared out of it sulkily.
The Duke walked up and down the hall, looking at the pictures of some of his ancestors—somewhat grotesque persons—with humorous appreciation. Between addressing the envelopes Sonia kept glancing at him. Once he caught her eye, and smiled at her. Germaine's back was eloquent of her displeasure. The Duke stopped at a gap in the line of pictures in which there hung a strip of old tapestry.
"I can never understand why you have left all these ancestors of mine staring from the walls and have taken away the quite admirable and interesting portrait of myself," he said carelessly.
Germaine turned sharply from the window; Sonia stopped in the middle of addressing an envelope; and both the girls stared at him in astonishment.
"There certainly was a portrait of me where that tapestry hangs. What have you done with it?" said the Duke.
"You're making fun of us again," said Germaine.
"Surely your Grace knows what happened," said Sonia.
"We wrote all the details to you and sent you all the papers three years ago. Didn't you get them?" said Germaine.
"Not a detail or a newspaper. Three years ago I was in the neighbourhood of the South Pole, and lost at that," said the Duke.
"But it was most dramatic, my dear Jacques. All Paris was talking of it," said Germaine. "Your portrait was stolen."
"Stolen? Who stole it?" said the Duke.
Germaine crossed the hall quickly to the gap in the line of pictures.
"I'll show you," she said.
She drew aside the piece of tapestry, and in the middle of the panel over which the portrait of the Duke had hung he saw written in chalk the words:
ARSENE LUPIN
"What do you think of that autograph?" said Germaine.
"'Arsene Lupin?'" said the Duke in a tone of some bewilderment.
"He left his signature. It seems that he always does so," said Sonia in an explanatory tone.
"But who is he?" said the Duke.
"Arsene Lupin? Surely you know who Arsene Lupin is?" said Germaine impatiently.
"I haven't the slightest notion," said the Duke.
"Oh, come! No one is as South-Pole as all that!" cried Germaine. "You don't know who Lupin is? The most whimsical, the most audacious, and the most genial thief in France. For the last ten years he has kept the police at bay. He has baffled Ganimard, Holmlock Shears, the great English detective, and even Guerchard, whom everybody says is the greatest detective we've had in France since Vidocq. In fact, he's our national robber. Do you mean to say you don't know him?"
"Not even enough to ask him to lunch at a restaurant," said the Duke flippantly. "What's he like?"
"Like? Nobody has the slightest idea. He has a thousand disguises. He has dined two evenings running at the English Embassy."
"But if nobody knows him, how did they learn that?" said the Duke, with a puzzled air.
"Because the second evening, about ten o'clock, they noticed that one of the guests had disappeared, and with him all the jewels of the ambassadress."
"All of them?" said the Duke.
"Yes; and Lupin left his card behind him with these words scribbled on it:"
"'This is not a robbery; it is a restitution. You took the Wallace collection from us.'"
"But it was a hoax, wasn't it?" said the Duke.
"No, your Grace; and he has done better than that. You remember the affair of the Daray Bank—the savings bank for poor people?" said Sonia, her gentle face glowing with a sudden enthusiastic animation.
"Let's see," said the Duke. "Wasn't that the financier who doubled his fortune at the expense of a heap of poor wretches and ruined two thousand people?"
"Yes; that's the man," said Sonia. "And Lupin stripped Daray's house and took from him everything he had in his strong-box. He didn't leave him a sou of the money. And then, when he'd taken it from him, he distributed it among all the poor wretches whom Daray had ruined."
"But this isn't a thief you're talking about—it's a philanthropist," said the Duke.
"A fine sort of philanthropist!" broke in Germaine in a peevish tone. "There was a lot of philanthropy about his robbing papa, wasn't there?"
"Well," said the Duke, with an air of profound reflection, "if you come to think of it, that robbery was not worthy of this national hero. My portrait, if you except the charm and beauty of the face itself, is not worth much."
"If you think he was satisfied with your portrait, you're very much mistaken. All my father's collections were robbed," said Germaine.
"Your father's collections?" said the Duke. "But they're better guarded than the Bank of France. Your father is as careful of them as the apple of his eye."
"That's exactly it—he was too careful of them. That's why Lupin
