must have been built in the time of Maria Theresa,... but he was sure of one thing, and that was that he would soon find out to whom it belonged. At present it was the garden which interested him, and he was anxious to see where it ended. A few moments’ further inspection showed him what he wanted to know. The garden extended to the beginning of the park-like grounds which surrounded the old house with the mansard roof. A tall iron railing separated the garden from the park, but this railing did not extend down as far as the quiet lane. Where it ended there was a light, well-built wooden fence. Along the street side of the fence there was a high thick hedge. Muller walked along this hedge until he came to a little gate. Then crossing the street, he saw that the house whose windows glistened in the sunlight was a house which he knew well from its other side, its front facade.

When he met Muller, the old man halted, touched his cap and asked in a confidential tone: “I suppose you’ve been to see the place already?” “Which place?” was Muller’s reserved answer. “Why, I mean the place where they
