Then, and not till then, did the affair of the Tramp come under discussion. What seemed most puzzling was why the Policeman had not arrested him after all. They could not make it out at all; it seemed a mystery. There was something quite unusual about it altogether. Uncle Felix and Judy had been wonderful, but-- "Did you see him blink," said Tim, "when Judy went up and gave it him hot?" "Yes," observed Maria, who had done nothing herself but stare. "I did." The brother, however, was not so sure. "I think he really believed her," he declared with assurance, proud of her achievement. "He really saw him young and with a sword and curly hair and all that." Judy looked at him with surprise. Her tears had ceased flowing by this time. "Of course," she said. "Didn't _you?_" There was pain in her voice in addition to blank astonishment. "Of course we did," said Uncle Felix quickly with decision. "Of course we did." As they went into the house, however, Uncle Felix lingered behind a moment as though he had forgotten something. His face wore a puzzled expression. He seemed a little bewildered. He walked into the hat-rack first, then into the umbrella-stand, then stopped abruptly and put his hand to his head. "Headache?" asked Tim, who had been watching him. His uncle did not hear the question, at least he did not answer. Instead he pulled something hurriedly out of his waistcoat pocket, held it to his ear, listened attentively a moment, and then gave a sudden start. "What is it, Uncle?" "Oh, nothing," was the reply; "my watch has stopped, that's all." He stood still a moment or two, reflecting deeply. His eyebrows went up and down. He pursed his lips. "Odd," he continued, half to himself; "I'm sure I wound it up last night...!" he added, "it's going again now. It stopped--only for a moment!" "Aha," said Tim significantly, and looked about him. He waited breathlessly for something more to happen. But nothing did happen--just then. Only, when at last Uncle Felix looked down, their eyes met and a flash of knowledge too enormous ever to be forgotten passed noiselessly between the two of them. "Perhaps...!" murmured his uncle. "I wonder...!" That was all. CHAPTER XI JUDY'S PARTICULAR ADVENTURE
