“One must have a feeling of personal security,” remarked Carovius. He wondered whether the Baron had reached his majority. Eberhard replied that he had just completed his twenty-first year, and that certain things had made him feel that it would be wise to live independent of his family and to renounce his claims to all family rights for the time being. What he really had in mind was the desire to avoid, so far as humanly possible, association with all professional money-lenders. Herr Carovius felt that this was an extremely serious case. He claimed moreover to understand it perfectly and to be ready for anything, but insisted that nothing must be withheld, that he must be given undiluted wine. He made this remark just as if he were holding a glass of old Johannisberger out in the rain, sniffing as he did with appreciative nostrils. “I am very discreet,” he said, “very taciturn.” He looked at the Baron tenderly. The young Baron nodded. “The wearer of purple is recognised wherever he goes,” continued Herr Carovius, “and if he lays the purple aside he stands at once in need of reticent friends. I am reserved.” The Baron nodded again. “If you will permit me, I shall visit you in a few days.” With that he ended the conversation. He started off toward the Avenue, walking stiffly. It was not hard to see that he was ill at ease. Herr Carovius walked away with mincing, merry steps down toward the small end of the alley, singing an aria from the “Barber of Seville” as he went. At the end of the first week he was taken down with a disconcerting suspicion that the Baron had made a fool of him. He was filled with a wrath that had to be cooled. One morning, just as he was leaving his apartment, he saw two milk cans filled with milk standing in the outer hall. One was for the first floor, the other for the second. The milkmaid had placed them there for the time being, and had gone over to have a little morning chat with her neighbour. Herr Carovius went to his lumber-room, which also served as the kitchen, took down a jug of vinegar, came back, looked around with all the caution he could summon, and then poured half of the contents of the jug into one can and the other half into the other. Two days later he decided not to give Cæsar anything to eat, so that he would terrify the neighbours by his howling. This worked. The dog howled and whined and barked night after night. It was enough to melt the heart of a stone. Nobody could sleep. Andreas Döderlein went to the police, but they told him that the case was beyond their jurisdiction.
