Monsieur Lecoq, Volume II by Emile Gaboriau

Martial De Sairmeuse's unexpected visit to the Chateau de Courtornieu had alarmed Aunt Medea even more than it had alarmed Blanche. In five minutes, more ideas passed through the dependent relative's mind than during the last five years. In fancy she already saw the gendarmes at the chateau; her niece arrested, confined in the Montaignac prison, and brought before the Assize Court. She might herself remain quiet if that were all there was to fear! But suppose she were compromised, suspected of complicity as well, dragged before the judges, and even accused of being the only culprit! At this thought her anxiety reached a climax, and finding the suspense intolerable, she ventured downstairs. She stole on tiptoe into the great ball room, and applying her ear to the keyhole of the door leading into the blue salon, she listened attentively to Blanche and Martial's conversation. What she heard convinced her that her fears were groundless.

She drew a long breath, as if a mighty burden had been lifted from her breast. But a new idea, which was to grow, flourish, and bear fruit, had just taken root in her mind. When Martial left the room, she at once opened the door by which she had been standing, and entered the blue reception room, thus admitting as it were that she had been a listener. Twenty-four hours earlier she would not even have dreamed of committing such an audacious act. "Well," she exclaimed, "Blanche, we were frightened for nothing."
