"Jack was given the special duty of looking after Mehemet Ali and his companions during their residence in London. It was his business to afford them every assistance in his power, to procure them police protection, obtain for them the best advice attainable in the diamond trade, and generally place at their disposal all the resources which the British Government itself could command if it undertook such a curious task. He had been with them about a month--not hourly engaged, you understand, as once the preliminary arrangements were made, he had little further trouble--but he used to call there every morning and afternoon to see if he could render any assistance. Matters had progressed so favourably until the day before yesterday, that in another month he hoped to see the last of them. He was always saying that he would be glad when the business was ended, as he did not like to be officially connected with the fate of a few little bits of stone that happened to be so immensely valuable." "Did your brother call there as usual on Monday afternoon?" said Brett. "Yes; he came straight here from Albert Gate, and had tea with uncle and myself. He sat in the very chair and in the very position you now occupy. I can remember him saying: 'By jove! the hen's egg'--that is what he used to call the big diamond--'is turning out in fine style.' He even discussed the possibility of bringing us to see the collection when it was finished and before it left this country." "Did your brother say why the diamonds were brought to this country in the first instance?" "Yes; the Sultan and his advisers seemed to think the work of cutting them could be performed more safely and expeditiously here than anywhere else. Even the Turk has a high regard for the manner in which law and order are maintained in Britain. Yet the sequel has shown that the diamonds and their guardians were perhaps in greater danger here than they would have been in Constantinople." "Was that the only reason?" said Brett, who had apparently made up his mind with reference to the pattern of the carpet, and was now gazing into the bright fire which danced merrily in the grate, for the day though fine was chilly. The girl wrinkled her brows in thought before she answered: "I think I do remember Jack saying that he believed there was some State business mixed up in the affair, but I am quite sure he did not know the exact facts himself." "Can you recollect any of the special precautions taken to protect the gems? Your brother may have mentioned some details in conversation, you know."
