"Lu Hudson, whom most people called 'Spanish Lu', was the owner of the next ranch, and a very disagreeable neighbour. He was a big, rough, dark, hot-tempered fellow, with a bad reputation for picking quarrels and using his revolver. He and Uncle Carr were continually having lawsuits about the boundary of their ranches, and his sheep were constantly trespassing on the Buller's Creek ranges. He had the greatest admiration for Darkie, and several times had asked to buy her, but Uncle Carr had always curtly refused to part with her. The last time there had been trouble about the boundary, Spanish Lu had sworn that he would pay Uncle Carr out, and he was just the sort of desperate fellow to keep his word. Of course the first thing to be done was to ride round the ranch and see whether Darkie could be found anywhere.
