She went to a pile of music which was on a little table, for the purpose of selecting a piece of sufficient simplicity to enable a tyro to display his powers, or want of them. He was between her and the window. In passing the window he glanced through it. As he did so, he gave a sudden start--a start, in fact, which amounted to a positive jump. His hat dropped from his hand, and, wholly regardless that he was leaving it lying on the floor, he hurried backwards, keeping in the shadow, and as far as possible from the window. The action was so marked that it was impossible it should go unnoticed. It filled Madge Brodie with a sense of shock which was distinctly disagreeable. Her eyes, too, sought the window--it looked out on to the road. A man, it struck her, of emphatically sinister appearance, was loitering leisurely past. As she looked he stopped dead, and, leaning over the palings, stared intently through the window. It was true that the survey only lasted for a moment, and that then he shambled off again, but the thing was sufficiently conspicuous to be unpleasant. So startled was she by the connection which seemed to exist between the fellow's insolence and her visitor's perturbation that, without thinking of what she was doing, she placed the first piece she came across upon the music-stand--saying, as she did so: "Let me see what you can do with this." Her words were unheeded. Her visitor was drawing himself into an extreme corner of the room, in a fashion which, considering his size and the muscle which his appearance suggested, was, in its way, ludicrous. It was not, however, the ludicrous side which occurred to Madge; his uneasiness made her uneasy too. She spoke a little sharply, as if involuntarily. "Do you hear me? Will you be so good as to try this piece, and let me see what you can make of it." Her words seemed to rouse him to a sense of misbehaviour. "I beg your pardon; I am afraid you will think me rude, but the truth is, I--I have been a little out of sorts just lately." He came briskly towards the piano; glancing however, as Madge could not help but notice, nervously through the window as he came. The man outside was gone; his absence seemed to reassure him. "Is this the piece you wish me to play? I will do my best." He did his best--or, if it was not his best, his best must have been something very remarkable indeed. The piece she had selected--unwittingly--was a Minuet of Mozart's. A dainty trifle; a pitfall for the inexperienced; seeming so simple, yet needing the soul, and knowledge, of a virtuoso to make anything of it at all. Hardly the sort of thing to set before a seeker after music lessons, whose acquaintance with music, for all she knew, was limited to picking out the notes upon the keyboard. At her final examination she herself had chosen it, first because she loved it, and, second, because she deemed it to be something which would enable her to illustrate her utmost powers at their very best.
