"We will go a step further before I answer that question. To-day, Wigan, we have made a curious discovery. All Mr. Ottershaw's walking-sticks were very stout ones, and that he really used them, not merely carried them, the condition of the ferrules proves. Moreover, there was a curious fact about his boots. They were large, the right one being a little larger than the other, and the right boot in every pair was the least trodden down--indeed, showed little wear either inside or out. I wonder if Sims could explain this?" Zena was leaning forward, her eyes fixed upon the professor, and I was thinking of a boot with a hollow heel. "Let's go back to the will for a moment," said Quarles. "Although Mr. Ottershaw desired to be cremated, he did not put it in the form of a condition, as he might reasonably have done. He even mentions the expense, and, in fact, gives his relatives quite a good excuse for not doing as he desires. It seems to me he didn't care much one way or the other, and that his object was to make the relatives suffer for their greed, and suffer all the more because he didn't actually leave the money away from them. It was Zena's absurd question, Wigan, and her anger that the Bryants had not carried out the old man's wish, which gave me the germ of a theory. I believe if they had had him cremated they would have found the treasure. He gave them a chance which they lost by burying him." "Then you believe Sims carried out his master's wishes?" I said. "I do." "And managed to have the treasure buried with him?" "I do not believe Sims knows anything about a treasure," said Quarles; "and I think he speaks the truth when he says that nothing but the body was buried. But Sims knew more about his master than anyone else. He could tell us something about their doings in Switzerland and Germany, for instance. He was very fond of his master, and was trusted by him." "We want to know what happened just after Mr. Ottershaw's death," I said. "To know what occurred abroad will not help us much." "I think it will," Quarles returned. "Supposing Mr. Ottershaw had an accident abroad which necessitated the amputation of his right leg, and supposing, in Germany perhaps, he got the very best artificial limb money could purchase?" "A wooden leg!" I exclaimed.
