"I fail to see why Mr. Talbot was dragged into the matter at all. On the straightforward assumption that Turks were engaged in the pleasant occupation of taking other Turks' lives--an assumption to which, by the way, I attach no great amount of credence--why did they not allow Mr. Talbot to go quietly to his own home? It was not that they feared more speedy discovery of their crime. The hour was then late; it was tolerably certain that he would make no move which might prove injurious to them until next morning, and then the whole affair was bound to be discovered by the police in the ordinary course of events." "I don't quite follow you, sir," said Winter, with a puzzled tone in his voice. They had, for the sake of quietude, turned into the Park, and were now walking towards Hyde Park Corner. "What do you mean by saying that Mr. Talbot would make no move in the matter until next morning?" "Oh, I forgot," said Brett. "Of course, you don't know why the diamonds were stolen?" "For the same reason that all other diamonds are stolen, I suppose." "Oh, dear no," laughed the barrister. "This is a political crime." "Political!" said the amazed policeman. "Well, we won't quarrel about words, and as there are perhaps no politics in Turkey, we will call it dynastic or any other loud-voiced adjective which serves to take it out of the category of simple felony. Why? I cannot at this moment tell you, but you may be perfectly certain that the disappearance of those diamonds from the custody of Mehemet Ali Pasha will not cause the Sultan to sleep any more soundly." "What beats me, Mr. Brett," said the detective, viciously prodding the gravel path with his stick, "is how you ferret out these queer facts--fancies some people would call them, as I used to do until I knew you better." "In this case it is simple enough. By mere chance I happened to read this morning that there had been some little domestic squabble in royal circles at Constantinople. I don't know whether you are acquainted with Turkish history, Mr. Winter, but it is a well-recognised principle that any Sultan is liable to die of diseases which are weird and painfully sudden; for instance, the last one is popularly supposed to have plunged a long sharp scissors into his jugular vein; others drank coffee that disagreed with them, or smoked cigarettes too highly perfumed. In any case, the invariable result of these eccentricities has been that a fresh Sultan occupied the throne. Now, don't forget that I am simply theorising, for I know no more of this business than you do at this moment, but I still think that you will find some connection between my theory and that which has actually occurred. At any rate, I have said sufficient to prove to you the importance of not being too ready to make arrests."
