As he said this, he mounted to his door and disappeared under the vines, hanging like a shroud over the front of the house. In another moment the rich peal of an organ sounded from within, followed by the prolonged howling of Rudge, who, either from a too keen appreciation of his master’s music or in utter disapproval of it,—no one, I believe, has ever been able to make out which,—was accustomed to add this undesirable accompaniment to every strain from the old man’s hand. The playing did not cease because of these outrageous discords. On the contrary, it increased in force and volume, causing Rudge’s expression of pain or pleasure to increase also. The result can be imagined. As I listened to the intolerable howls of the dog cutting clean through the exquisite harmonies of his master, I wondered if the shadows cast by the frowning structure of the great Moore house were alone to blame for Uncle David’s lack of neighbors. Meantime, Hibbard, who was the first to hear my signal, came running down the block. As he joined me, the light, or what we chose to call a light, appeared again in the window toward which my attention had been directed. “Some one’s in the Moore house!” I declared, in as matter of-fact tones as I could command. Hibbard is a big fellow, the biggest fellow on the force, and so far as my own experience with him had gone, as stolid and imperturbable as the best of us. But after a quick glance at the towering walls of the lonely building, he showed decided embarrassment and seemed in no haste to cross the street. With difficulty I concealed my disgust. “Come,” I cried, stepping down from the curb, “let’s go over and investigate. The property is valuable, the furnishings handsome, and there is no end of costly books on the library shelves. You have matches and a revolver?” He nodded, quietly showing me first the one, then the other; then with a sheepish air which he endeavored to carry of with a laugh, he cried: “Have you use for ’em? If so, I’m quite willing to part with ’em for a half-hour.” I was more than amazed at this evidence of weakness in one I had always considered as tough and impenetrable as flint rock. Thrusting back the hand with which he had half drawn into view the weapon I had mentioned, I put on my sternest sir and led the way across the street. As I did so, tossed back the words: “We may come upon a gang. You do not wish me to face some half-dozen men alone?” “You won’t find any half-dozen men there,” was his muttered reply. Nevertheless he followed me, though with less spirit than I liked, considering that my own manner was in a measure assumed and that I was not without sympathy—well, let me, say, for a dog who preferred howling a dismal accompaniment to his master’s music, to keeping open watch over a neighborhood dominated by the unhallowed structure I now propose to enter.
