'Nothing to say!' exclaimed the banker; 'why, this is a tacit admission of guilt. We had better call in the gendarmes at once.'

'I think,' said Dufour, 'the young man's refusal to speak is owing to the entreaties of Mademoiselle de la Tour, whom we overheard implore him, for her sake, or as he loved her, not to say a word.'

'What do you say?' exclaimed Derville, with quick interrogation, 'for the sake of Mademoiselle de la Tour! Bah! you could not have heard aright.'

'Pardon, monsieur,' said the clerk who had accompanied Dufour: 'I also distinctly heard her so express herself—but here is the lady herself.'

The entrance of Marie, accompanied by Jeanne Favart, greatly surprised and startled M. Derville; he glanced sharply in her face, but unable to encounter the indignant expression he met there, quickly averted his look, whilst a hot flush glowed perceptibly out of his pale features. At her request, seconded by M. Blaise, Derville repeated his previous story; but his voice had lost its firmness, his manner its cold impassibility.

'I wish Monsieur Derville would look me in the face,' said Marie, when Derville had ceased speaking. 'I am here as a suppliant to him for mercy.'

'A suppliant for mercy!' murmured Derville, partially confronting her.

'Yes; if only for the sake of the orphan daughter of the Monsieur de la Tour who first helped you on in life, and for whom you not long since professed regard.'

Derville seemed to recover his firmness at these words: 'No,' he said; 'not even for your sake, Marie, will I consent to the escape of such a daring criminal from justice.'

'If that be your final resolve, monsieur,' continued Marie, with kindling, impressive earnestness, 'it becomes necessary that, at whatever sacrifice, the true criminal—whom assuredly Hector Bertrand is not—should be denounced.'
