“Well,” Mr. Prendergast said, “if you like to undertake a wild goose chase of this sort it is your business, and not mine; but I consider the idea is the most Utopian that I ever heard of. As to where the tent stood, is it likely that a man would remember to within a hundred yards where a tent stood fourteen years ago? Why, you might dig up acres and acres of ground and not be sure then that you had hit upon the right place.” “There is one other circumstance, Mr. Prendergast,” Mark said quietly, “that has to be taken into consideration, and which renders it improbable that these diamonds were hidden anywhere by my uncle himself at that time. He certainly spoke of the whole of this treasure collectively. It is morally certain that he would not carry all these jewels that he had been collecting about with him, and certainly not his treasure in money. He must, therefore, have sent these diamonds to the person, whoever he may be, who had the keeping of his other jewels and of his money. This certainly points to a bank.” “There is a sensible conjecture. Yes, there is something in that. He certainly could not have carried about him 50,000 pounds in gold and as much in jewelry; it would have been the act of a madman, and Colonel Thorndyke, although eccentric and cranky, was not mad. But, on the other hand, he may have carried about a banker's passbook, or what is equivalent to it, for the amount that had been deposited with a native banker or agent, together with a receipt for the box containing the jewels, and this he might have hidden with the diamonds.” “I don't think that he would have done that; there could have been no object for his putting the power of demanding his money and valuables out of his possession.” “Well, well,” the lawyer said testily, “it is of no use arguing now what he might or might not have done. A man who would have taken the trouble that he did to prevent his daughter knowing that she was an heiress, and fancied that he was followed about by black fellows, might do anything, reasonable or unreasonable, under the sun. At any rate, Mr. Thorndyke, I will carry out your instructions as to inquiries in London, and will duly inform you of the result; beyond that I must really decline to give any advice or opinion upon the matter, which is altogether beyond me.” On leaving the lawyer's, Mark went to Bow Street, and related to the chief the circumstances attending his father's murder.
