"But this weapon has been for fifty years in Glen Tochan. Its history is thoroughly established." "Is it? Who made it? Whose crest does it bear? What does this motto signify? If you wanted to kill a man would you use this toy? Why was not the sword itself employed?" "That string of questions leaves me out, Mr. Brett." "I am equally uninformed. I can only answer the last one. The sword is intended for suicidal purposes, the Ko-Katana for an enemy. This is a case of murder, not suicide." The detective wheeled sharply on his heels, thereby upsetting Charles Peace's telescopic ladder. "You suspect Okasaki!" he cried. "My dear fellow! Okasaki is, say, five feet nothing. The murderer is five feet ten inches in height. Japanese are clever people, but they are not--telescopes," and he picked up the ladder. Winter grinned. "You always make capital out of my blunders," he said. "Pooh! My banking account is limited. Let us go. The moral atmosphere in this room is vile." Outside the Central Police Office they separated, Brett to pay some long-neglected calls, Winter to hunt up Capella's movements and initiate inquiries about Okasaki. The detective came to Brett's chambers at five o'clock, in a great state of excitement. "Thank goodness you are at home, sir." he cried, when Smith admitted him to the barrister's sanctum. "Capella is off to Naples." Naples, the scene of his marriage! What did this journey portend? Naught but the gravest considerations would take him so far away from home when he knew that David and Helen were reunited. "How did you discover this fact?" asked Brett, awaking out of a brown study. "Easily enough, as it happened. Ninety-nine per cent. of gentlemen's valets are keen sports. Barbers and hotel-porters run them close. I do a bit that way myself--" The barrister groaned. "Not often, sir, but this is holiday time, you see. Anyhow, I gave the hall-porter, whom I know, the wink to come to a neighbouring bar during his time off for tea. He actually brought Capella's man--William his name is--with him. I told them I had backed the first winner to-day, an eight to one chance, and that started them. I offered to put them on a certainty next week, and William's face fell. 'It's a beastly nuisance,' he said, 'I'm off to Naples with my boss to-morrow.' 'Well,' said I, 'if you're not going before the night train, perhaps I may be able--' But that made him worse, because they leave by the 11 A.M., Victoria." Brett began to pace the room. He could not make up his mind to visit Naples in person. For one thing, he did not speak Italian. But Capella must be followed. At last he decided upon a course of action. "Winter," he said, "do you know a man we can trust, an Italian, or better still, an Italian-speaking Englishman, who can undertake this commission for us?" "Would you mind ringing for Smith, sir?" replied the detective, who seemed to be mightily pleased with himself. Smith appeared.
