"Me, sir? No, sir. I haven't brought the pendant," said Irma.

"You're quite sure?" said M. Formery.

"Yes, sir; I haven't seen the pendant. Didn't Mademoiselle Germaine leave it on the bureau?" said Irma.

"How do you know that?" said M. Formery.

"I heard Mademoiselle Germaine say that it had been on the bureau. I thought that perhaps Mademoiselle Kritchnoff had put it in her bag."

"Why should Mademoiselle Kritchnoff put it in her bag?" said the Duke quickly.

"To bring it up to Paris for Mademoiselle Germaine," said Irma.

"But what made you think that?" said Guerchard, suddenly intervening.

"Oh, I thought Mademoiselle Kritchnoff might have put it in her bag because I saw her standing by the bureau," said Irma.

"Ah, and the pendant was on the bureau?" said M. Formery.

"Yes, sir," said Irma.

There was a silence. Suddenly the atmosphere of the room seemed to have become charged with an oppression--a vague menace. Guerchard seemed to have become wide awake again. Germaine and the Duke looked at one another uneasily.

"Have you been long in the service of Mademoiselle Gournay-Martin?"

said M. Formery.

"Six months, sir," said Irma.

"Very good, thank you. You can go," said M. Formery. "I may want you again presently."

Irma went quickly out of the room with an air of relief.

M. Formery scribbled a few words on the paper before him and then said: "Well, I will proceed to question Mademoiselle Kritchnoff."

"Mademoiselle Kritchnoff is quite above suspicion," said the Duke quickly.

"Oh, yes, quite," said Germaine.

"How long has Mademoiselle Kritchnoff been in your service, Mademoiselle?" said Guerchard.

"Let me think," said Germaine, knitting her brow.

"Can't you remember?" said M. Formery.

"Just about three years," said Germaine.

"That's exactly the time at which the thefts began," said M. Formery.

"Yes," said Germaine, reluctantly.

"Ask Mademoiselle Kritchnoff to come here, inspector," said M. Formery.

"Yes, sir," said the inspector.

"I'll go and fetch her--I know where to find her," said the Duke quickly, moving toward the door.

"Please, please, your Grace," protested Guerchard. "The inspector will fetch her."

The Duke turned sharply and looked at him: "I beg your pardon, but do you--" he said.

"Please don't be annoyed, your Grace," Guerchard interrupted. "But M.

Formery agrees with me--it would be quite irregular."

"Yes, yes, your Grace," said M. Formery. "We have our method of procedure. It is best to adhere to it--much the best. It is the result of years of experience of the best way of getting the truth."

"Just as you please," said the Duke, shrugging his shoulders.

The inspector came into the room: "Mademoiselle Kritchnoff will be here in a moment. She was just going out."

"She was going out?" said M. Formery. "You don't mean to say you're letting members of the household go out?"

"No, sir," said the inspector. "I mean that she was just asking if she might go out."

M. Formery beckoned the inspector to him, and said to him in a voice too low for the others to hear:

"Just slip up to her room and search her trunks."

"There is no need to take the trouble," said Guerchard, in the same low voice, but with sufficient emphasis.

"No, of course not. There's no need to take the trouble," M. Formery repeated after him.

The door opened, and Sonia came in. She was still wearing her travelling costume, and she carried her cloak on her arm. She stood looking round her with an air of some surprise; perhaps there was even a touch of fear in it. The long journey of the night before did not seem to have dimmed at all her delicate beauty. The Duke's eyes rested on her in an inquiring, wondering, even searching gaze. She looked at him, and her own eyes fell.

"Will you come a little nearer. Mademoiselle?" said M. Formery. "There are one or two questions--"

"Will you allow me?" said Guerchard, in a tone of such deference that it left M. Formery no grounds for refusal.

M. Formery flushed and ground his teeth. "Have it your own way!" he said ungraciously.

"Mademoiselle Kritchnoff," said Guerchard, in a tone of the most good-natured courtesy, "there is a matter on which M. Formery needs some information. The pendant which the Duke of Charmerace gave Mademoiselle Gournay-Martin yesterday has been stolen."

"Stolen? Are you sure?" said Sonia in a tone of mingled surprise and anxiety.

"Quite sure," said Guerchard. "We have exactly determined the conditions under which the theft was committed. But we have every reason to believe that the culprit, to avoid detection, has hidden the pendant in the travelling-bag or trunk of somebody else in order to--"

"My bag is upstairs in my bedroom, sir," Sonia interrupted quickly.

"Here is the key of it."

In order to free her hands to take the key from her wrist-bag, she set her cloak on the back of a couch. It slipped off it, and fell to the ground at the feet of the Duke, who had not returned to his place beside Germaine. While she was groping in her bag for the key, and all eyes were on her, the Duke, who had watched her with a curious intentness ever since her entry into the room, stooped quietly down and picked up the cloak. His hand slipped into the pocket of it; his fingers touched a hard object wrapped in tissue-paper. They closed round it, drew it from the pocket, and, sheltered by the cloak, transferred it to his own. He set the cloak on the back of the sofa, and very softly moved back to his place by Germaine's side. No one in the room observed the movement, not even Guerchard: he was watching Sonia too intently.
