When all was in place, it was really quite inviting. I had a small lamp stove, so we need only go out for dinners. We began to feel more settled than for a long time, especially, as Julius had in the meantime found a business opening which was entirely satisfactory. We saw nothing at all of the other lodgers; but this did not disturb us, as we were in no hurry to make acquaintances. We felt that it was best to be circumspect in a city of this size and make-up. Our evenings were our pleasantest times, sitting on either side of the reading-lamp, with Bruno stretched at our feet; so I was inclined to object one evening, when Julius announced at dinner that he had promised to give a few hours to helping a young friend of his to straighten out his accounts. He had promised, though; so I had to yield. He set off betimes, so as to be home earlier. I locked the door after him, as I always did, and began to make myself as comfortable as possible for a quiet hour or two, with a new magazine. Before I had finished cutting the leaves, I was struck with surprise at Bruno's actions. He crept in a very stealthy manner to the door, and stood there in an attitude of listening, with every nerve and muscle tense. I watched him a minute, and then asked,-- "What is it, Boonie?" He did not look around; he waved his tail once or twice, then resumed his tense pose. Thoroughly surprised, I went softly to him, and stood also listening. I could hear nothing but a faint rustling, a suppressed whispering, and the soft click of a latch. I touched Bruno's head; he looked up at me, and I saw he was holding his lip between his side-teeth, as he had a way of doing when he was very much puzzled or excited. I tried to coax him away from the door, but he refused to come. I made sure the bolt was shot, and then sat down at a little distance to watch him. There was a door in the middle of one side of the room, which, when we took possession, we had found to be nailed up. We utilized the recess with the aid of some draperies, as a place to hang clothing. Bruno went to this door, thrusting his head in among the clothes. He listened there for a long time, probably ten minutes; he returned again to the other door; then he gave a low growl, followed by several half-suppressed barks, and lay down against it. I forgot all about my book, and sat watching to see what he would do next. The evening seemed endless. At last I heard Julius below in the hall; Bruno sprang up when I opened the door, and went clattering down the stairs to escort him up. It was not late, only about ten. I at once told Julius of the queer evening we had spent, and had the satisfaction of seeing him as thoroughly puzzled as I had been. We sat until a late hour discussing it, then gave it up as something quite beyond us.
