One evening, along towards spring, he chanced to go into the backyard to feed Cæsar. He looked up, and saw Marguerite standing on the balcony. She did not see him, for she was also looking up. On the balcony of the second floor, across the court from her, stood Friedrich Benda, responding to some mute signals Marguerite was giving him. Finally they both stopped and merely looked at each other, until Marguerite caught sight of her brother, when she quickly disappeared behind the glass door draped with green curtains. “Aha,” thought Carovius, “there’s something up.” The scene warmed his very blood. From that day on he avoided the court. He sat instead for hours at a time in a room from which he could look out through a crack and see everything that was taking place at the windows and on the balconies. He discovered that signals were being sent from the first floor up to the second by changing the position of a flower pot on the railing of the balcony, and that these signals were answered by having a yellow cloth flutter on now a vertical, now a horizontal pole. At times Marguerite would come out quite timidly, and look up; at times Benda appeared, and stood for a while at the window completely absorbed, as it seemed, in melancholy thoughts. Herr Carovius caught them together but on one single occasion. He opened the window as quickly as he could, and placed his ear so that he could hear what was being said, but it so happened that over in the adjoining yard some one was just then nailing a box together. As a result of the noise it was impossible for him to understand their remarks. Since that day they exchanged no more signals, and never again appeared on the balcony. Carovius rubbed his hands at the thought that the majestic Andreas Döderlein had after all grown horns. But his joy waned when he reflected that two other people were deriving profit from the situation. That should not be; that had to be corrected. And so he stood at times in the evening out in the narrow passage at the entrance to his apartment. His bathrobe fell down over his bony body in many folds. In his right hand he carried a candle. Thus equipped, he listened in, or rather into, the stillness of the house. At times he would take a dark lantern, walk up the stairs slowly, step by step, and listen, listen with the greedy ears of a man who was determined to hear something. There was something in the air that told him of secret, and of course illicit, transactions. Was it the same medium through which he learned of the weakening of Marguerite’s mind and the beclouding of her soul? Was it this that told him of her mental anxiety and the ever growing delusion of her terrified and broken heart?
