He went softly into the front room, keeping out of sight from the window. He was seized with a desire to wreak vengeance on this tormentor, but he was not quite clear how to do it, and must survey his ground first. Stepping behind the window-curtain, he peeped out between the curtain and the window-frame, and saw a small boy, whistling hard, with a long string in his hand, which descended into the area below. The musician stood on tiptoe, and looked down into the area; it was a sort of relief to him to see what this urchin was about. At the end of the string he perceived a dead mouse, which was being made to jump up and down and counterfeit life, as well as was possible under the circumstances, for the benefit of a young cat of the household, who was lying in wait for it, springing on it, and each time finding it drawn away from her just as she thought her claws were fast fixed in it. This boy was in fact an original genius, who had invented this way of amusing himself; he called it cat-fishing, and it was excellent sport. The musician suddenly flung up the window, and faced the boy, who seemed by no means disconcerted; he only left off whistling and looked hard at the musician. “What are you doing with the cat?” said the latter, with all the dignity he could put on. “What business have you to meddle with my cat, and make that infernal din in front of my house?” The boy began slowly to haul up the string, looking all the while steadily at the composer. “I say, guv’nor,” he said, with a mock show of friendly interest, “do you know as you’ve got a blob of ink at the end o’ your nose?” The composer was taken aback. He certainly did not know it, but nothing was more likely, considering how he had been pulling his moustache and scratching his head with fingers which, as he glanced at them, showed some traces of ink. He put his hand involuntarily to his nose, and half turned to the glass over the chimney-piece. There was not a stain there: the nose was innocent of ink. Instantly he returned to the window, but the boy was gone; all that was left of him was a distant sound of “There’s nae luck aboot the house” far down the street. The composer went gloomily back to his study, without a particle of music in his brain; the canary and the whistler had driven it all away. He sat down mechanically at his desk, but he might as well have sat down at the kitchen-table and tried to make it play like a piano.
