The Duke sprang forward and caught her as she was falling.
"Do you feel faint?" he said in an anxious voice.
"Thank you, you just saved me in time," muttered Sonia.
"I'm really very sorry," said Guerchard.
"Thank you, it was nothing. I'm all right now," said Sonia, releasing herself from the Duke's supporting arm.
She drew herself up, and walked quietly out of the room.
Guerchard went back to M. Formery at the writing-table.
"You made a clumsy mistake there, Guerchard," said M. Formery, with a touch of gratified malice in his tone.
Guerchard took no notice of it: "I want you to give orders that nobody leaves the house without my permission," he said, in a low voice.
"No one except Mademoiselle Kritchnoff, I suppose," said M. Formery, smiling.
"She less than any one," said Guerchard quickly.
"I don't understand what you're driving at a bit," said M. Formery. "Unless you suppose that Mademoiselle Kritchnoff is Lupin in disguise."
