“I insist upon knowing.”

“Alas, mademoiselle!” answered Prosper, “you will only too soon learn my misfortune and disgrace; then, yes, then you will applaud yourself for what you have done.”

She became more urgent; instead of commanding, she entreated; but Prosper was inflexible.

“Your uncle is in the adjoining room, mademoiselle, with the commissary of police and a detective. They will soon return. I entreat you to retire that they may not find you here.”

As he spoke he gently pushed her through the door, and closed it upon her.

It was time, for the next moment the commissary and Monsieur Fauvel entered. They had visited the main entrance and waiting-room, and had heard nothing of what had passed in the study.

But Fanferlot had heard for them.

This excellent bloodhound had not lost sight of the cashier. He said to himself, “Now that my young gentleman believes himself to be alone, his face will betray him. I shall detect a smile or a wink that will enlighten me.”

Leaving M. Fauvel and the commissary to pursue their investigations, he posted himself to watch. He saw the door open, and Madeleine appear upon the threshold; he lost not a single word or gesture of the rapid scene which had passed.

It mattered little that every word of this scene was an enigma. M. Fanferlot was skilful enough to complete the sentences he did not understand.
