"Secondly, I must put my machinery to work to discover the maid Mathilde, and secure her arrest. She will be a most important witness in the case. If she is a partner in Gualtier's guilt, she can clear up the whole mystery. "Thirdly, we must have information of all this sent to Miss Lorton's bankers in London, and her solicitors, so as to prevent Gualtier from accomplishing his fourth step, and also in order to secure their co-operation in laying a trap for him which will certainly insure his capture. "As for the younger Miss Lorton, she had better remain in Marseilles for six or eight weeks, so that if the elder Miss Lorton should escape she may find her here. Meantime the Neapolitan police will take care of her, if she is in Naples, and communicate to her where her sister is, so that she can join her, or write her. At any rate, Miss Lorton must be persuaded to wait here till he hears from her sister, or of her." Other things were yet to be done before the preliminary examinations could be completed. The first was the examination of the man who had disposed of the yacht to Gualtier. He was found without any difficulty, and brought before the chief. It seems he was a common broker, who had bought the vessel at auction, on speculation, because the price was so low. He knew nothing whatever about nautical matters, and hated the sea. He had hardly ever been on board of her, and had never examined her. He merely held her in his possession till he could find a chance of selling her. He had sold her for more than double the money that he had paid for her, and thought the speculation had turned out very good. Nothing had ever been told him as to any peculiarity in the construction of the yacht. As far as he knew, the existence of such could not have been found out. On being asked whether the purchaser had assigned any reason for buying the vessel, he said no; and from that fact the chief seemed to form a more respectful opinion of Gualtier than he had hitherto appeared to entertain. Common cunning would have been profuse in stating motives, and have given utterance to any number of lies. But Gualtier took refuge in silence. He bought the vessel, and said nothing about motives or reasons. And, indeed, why should he have done so? Obed and Windham visited the yacht, in company with the chief. She was in the dry dock, and the water had flowed out from her, leaving her open for inspection. Zillah's trunks were taken out and conveyed to her, though their contents were not in a condition which might make them of any future value. Still, all Zillah's jewelry was there, and all the little keepsakes which had accumulated during her past life. The recovery of her trunks gave her the greatest delight.
