"Now you will hear something." CHAPTER IX THE KO-KATANA Thinking aloud, rather than addressing his companions, Brett began again:-- "The man must have had some place in which to change his clothes, for he would not court attention by walking about in evening dress by broad daylight He met and spoke with Alan Hume-Frazer that afternoon. The result was unsatisfactory. The stranger resolved to visit him again at night--the night of the ball. In a country village on such an occasion, a swallow-tailed coat was a _passe-partout_, as many gentry had come in from the surrounding district." "Yes, that is so," broke in Hume. Brett momentarily looked through him, and the detective shook his head to deprecate any further interruption. "He could not enter Mrs. Eastham's house, for there everybody knew everybody else. He could not enter the library of the Hall, because the footman was on duty for several hours. Is not that so?" He seemed to bite both men with the question. "Yes," they answered. "Then he was compelled to hang about the avenue, watching his opportunity--his opportunity for what? Not to commit a murder! He was unarmed, or, at any rate, his implement was a haphazard choice, selected on the spur of the moment. He saw David Hume leave the dance, and watched his brief talk with the butler. He correctly interpreted Hume's preparations to await his cousin's arrival. Did Hume's sleepiness suggest the crime, and its probable explanation? Perhaps. I cannot determine that point now. Assuredly it gave the opportunity to commit a theft. Something was stolen from the secretaire. A bold rascal, to force a drawer whilst another man was in the room! Did he fear the consequences if he were caught? I think not. He succeeded in his object, and went off, but before he reached the gates he saw Miss Layton, whom he did not know, talking to the baronet. He secreted himself until the baronet entered the park alone. For some reason, he made his presence known, and walked with Sir Alan to the lawn outside the window, still retaining in his hand the small knife used to prise open the lock. There was a short and vehement dispute. Possibly the baronet guessed the object of this unexpected appearance. There may have been a struggle. Then the knife was sent home, with such singular skill that the victim fell without a word, a groan, to arouse attention. The murderer made off down the avenue, but he was far too cold-blooded to run away and encounter unforeseen dangers. No; he waited among the trees to ascertain what would happen when his victim was discovered, and frame his plans accordingly. It was then that he saw Helen Layton and David Hume. As soon as the news of the murder spread abroad the dance broke up. Amidst the wondering crowd, slowly dispersing in their carriages, he could easily slip away unseen, for the police, of course, were sure that David Hume killed his cousin. Don't you see, Winter?" The inspector did not see.
