Sonia, in an indifferent tone.
"We should be very much obliged if you would go to your room," said Guerchard. "Your meals will be sent up to you."
"What?" said Sonia, rising quickly; and she looked from Guerchard to the Duke. The Duke gave her the faintest nod.
"Very well, I will go to my room," she said coldly.
They accompanied her to the door of the outer drawing-room. Guerchard opened it for her and closed it after her.
"Really, M. Guerchard," said the Duke, shrugging his shoulders. "This last measure—a child like that!"
"Really, I'm very sorry, your Grace; but it's my trade, or, if you prefer it, my duty. As long as things are taking place here which I am still the only one to perceive, and which are not yet clear to me, I must neglect no precaution."
"Of course, you know best," said the Duke. "But still, a child like that—you're frightening her out of her life."
Guerchard shrugged his shoulders, and went quietly out of the room.
The Duke sat down in an easy chair, frowning and thoughtful. Suddenly there struck on his ears the sound of a loud roaring and heavy bumping on the stairs, the door flew open, and M. Gournay-Martin stood on the threshold waving a telegram in his hand.
M. Formery and the inspector came hurrying down the stairs behind him, and watched his emotion with astonished and wondering eyes.
"Here!" bellowed the millionaire. "A telegram! A telegram from the scoundrel himself! Listen! Just listen:"
"A thousand apologies for not having been able to keep my promise about the coronet. Had an appointment at the Acacias. Please have coronet ready in your room to-night. Will come without fail to fetch it, between a quarter to twelve and twelve o'clock."
"Yours affectionately,"
"ARSENE LUPIN."
"There! What do you think of that?"
"If you ask me, I think he's humbug," said the Duke with conviction.
"Humbug! You always think it's humbug! You thought the letter was humbug; and look what has happened!" cried the millionaire.
"Give me the telegram, please," said M. Formery quickly.
The millionaire gave it to him; and he read it through.
"Find out who brought it, inspector," he said.
The inspector hurried to the top of the staircase and called to the policeman in charge of the front door. He came back to the drawing-room and said: "It was brought by an ordinary post-office messenger, sir."
"Where is he?" said M. Formery. "Why did you let him go?"
"Shall I send for him, sir?" said the inspector.
"No, no, it doesn't matter," said M. Formery; and, turning to M. Gournay-Martin and the Duke, he said, "Now we're really going to have trouble with Guerchard. He is going to muddle up everything. This telegram will be the last straw. Nothing will persuade him now that this is not Lupin's work. And just consider, gentlemen: if Lupin had come last night, and if he had really set his heart on the coronet, he would have stolen it then, or at any rate he would have tried to open the safe in M. Gournay-Martin's bedroom, in which the coronet actually is, or this safe here"—he went to the safe and rapped on the door of it—"in which is the second key."
"That's quite clear," said the inspector.
"If, then, he did not make the attempt last night, when he had a clear field—when the house was empty—he certainly will not make the attempt now when we are warned, when the police are on the spot, and the house is surrounded. The idea is childish, gentlemen"—he leaned against the door of the safe—"absolutely childish, but Guerchard is mad on this point; and I foresee that his madness is going to hamper us in the most idiotic way."
He suddenly pitched forward into the middle of the room, as the door of the safe opened with a jerk, and Guerchard shot out of it.
"What the devil!" cried M. Formery, gaping at him.
"You'd be surprised how clearly you hear everything in these safes—you'd think they were too thick," said Guerchard, in his gentle, husky voice.
"How on earth did you get into it?" cried M. Formery.
"Getting in was easy enough. It's the getting out that was awkward. These jokers had fixed up some kind of a spring so that I nearly shot out with the door," said Guerchard, rubbing his elbow.
"But how did you get into it? How the deuce DID you get into it?" cried M. Formery.
"Through the little cabinet into which that door behind the safe opens. There's no longer any back to the safe; they've cut it clean out of it—a very neat piece of work. Safes like this should always be fixed against a wall, not stuck in front of a door. The backs of them are always the weak point."
"And the key? The key of the safe upstairs, in my bedroom, where the coronet is—is the key there?" cried M. Gournay-Martin.
Guerchard went back into the empty safe, and groped about in it. He came out smiling.
"Well, have you found the key?" cried the millionaire.
"No. I haven't; but I've found something better," said Guerchard.
"What is it?" said M. Formery sharply.
"I'll give you a hundred guesses," said Guerchard with a tantalizing smile.
"What is it?" said M. Formery.
"A little present for you," said Guerchard.
"What do you mean?" cried M. Formery angrily.
Guerchard held up a card between his thumb and forefinger and said quietly:
"The card of Arsene Lupin."
CHAPTER XIV
GUERCHARD PICKS UP THE TRUE SCENT
The millionaire gazed at the card with stupefied eyes, the inspector gazed at it with extreme intelligence, the Duke gazed at it with interest, and M. Formery gazed at it with extreme disgust.
"It's part of the same ruse—it was put there to throw us off the scent. It proves nothing—absolutely nothing," he said scornfully.
"No; it proves nothing at all," said Guerchard quietly.
"The telegram is the important thing—this telegram," said M. Gournay-Martin feverishly. "It concerns the coronet. Is it going to be disregarded?"
"Oh, no, no," said M. Formery in a soothing tone. "It will be taken into account. It will certainly be taken into account."
M. Gournay-Martin's butler appeared in the doorway of the drawing-room:
