Let the Diamond be.John Herncastle." That was all he ever wrote, and that came regularly to the day; until some six or eight months since, when the form of the letter varied for the first time.It ran now: "Sir, -- They tell me I am dying.Come to me, and help me to make my Will." Mr.Bruff went, and found him, in the little sub-urban villa, surrounded by its own grounds, in which he had lived alone, ever since he had left India.He had dogs, cats, and birds to keep him company; but no human being near him, except the person who came daily to do the housework, and the doctor at the bedside.The Will was a very simple matter.The Colonel had dissipated the greater part of his fortune in his chemical investigations.His Will began and ended in three clauses, which he dictated from his bed, in perfect possession of his faculties.The first clause provided for the safe keeping and support of his animals.The second founded a professorship of experimental chemistry at northern university.The third bequeathed the Moonstone as a birthday present to his niece, on condition that my father would act as executor.My father at first refused to act.On second thoughts, however, he gave way, partly because he was assured that the executorship would involve him in no trouble; partly because Mr.Bruff suggested, in Rachel's interest, that the Diamond might be worth something, after all.'

`Did the Colonel give any reason, sir,' I inquired, `why he left the Diamond to Miss Rachel?'

`He not only gave the reason -- he had the reason written in his Will,'

said Mr.Franklin.`I have got an extract, which you shall see presently.

Don't be slovenly minded, Betteredge! One thing at a time.You have heard about the Colonel's Will; now you must hear what happened after the Colonel's death.It was formally necessary to have the Diamond valued, before the Will could be proved.All the jewellers consulted, at once confirmed the Colonel's assertion that he possessed one of the largest diamonds in the world.The question of accurately valuing it presented some serious difficulties.

Its size made it a phenomenon in the diamond market; its colour placed it in a category by itself; and, to add to these elements of uncertainty, there was a defect, in the shape of a flaw, in the very heart of the stone.

Even with this last serious drawback, however, the lowest of the various estimates given was twenty thousand pounds.Conceive my father's astonishment!

He had been within a hair's-breadth of refusing to act as executor, and of allowing this magnificent jewel to be lost to the family.The interest he took in the matter now, induced him to open the sealed instructions which had been deposited with the Diamond.Mr.Bruff showed this document to me, with the other papers; and it suggests (to my mind) a clue to the nature of the conspiracy which threatened the Colonel's life.'

`Then you do believe, sir,' I said, `that there was a conspiracy?'

`Not possessing my father's excellent common sense,' answered Mr.Franklin, `I believe the Colonel's life was threatened, exactly as the Colonel said.

The sealed instructions, as I think, explain how it was that he died, after all, quietly in his bed.In the event of his death by violence (that is to say, in the absence of the regular letter from him at the appointed date), my father was then directed to send the Moonstone secretly to Amsterdam.

It was to be deposited in that city with a famous diamond-cutter, and it was to be cut up into from four to six separate stones.The stones were then to be sold for what they would fetch, and the proceeds were to be applied to the founding of that professorship of experimental chemistry, which the Colonel has since endowed by his Will.Now, Betteredge, exert those sharp wits of yours and observe the conclusion to which the Colonel's instructions point!'

I instantly exerted my wits.They were of the slovenly English sort;and they consequently muddled it all, until Mr.Franklin took them in hand, and pointed out what they ought to see.

`Remark,' says Mr.Franklin, `that the integrity of the Diamond, as a whole stone, is here artfully made dependent on the preservation from violence of the Colonel's life.He is not satisfied with saying to the enemies he dreads, "Kill me -- and you will be no nearer to the Diamond than you are now; it is where you can't get at it -- in the guarded strong-room of a bank." He says instead, "Kill me -- and the Diamond will be the Diamond no longer; its identity will be destroyed." What does that mean?"Here I had (as I thought) a flash of the wonderful foreign brightness.

`I know,' I said.`It means lowering the value of the stone, and cheating the rogues in that way!'

`Nothing of the sort,' says Mr.Franklin.`I have inquired about that.

The flawed Diamond, cut up, would actually fetch more than the Diamond as it now is; for this plain reason -- that from four to six perfect brilliants might be cut from it, which would be, collectively, worth more money than the large -- but imperfect -- single stone.If robbery for the purpose of gain was at the bottom of the conspiracy, the Colonel's instructions absolutely made the Diamond better worth stealing.More money could have been got for it, and the disposal of it in the diamond market would have been infinitely easier, if it had passed through the hands of the workmen of Amsterdam.'

`Lord bless us, sir!' I burst out.`What was the plot, then?'

`A plot organized among the Indians who originally owned the jewel,'

says Mr.Franklin -- `a plot with some old Hindoo superstition at the bottom of it.That is my opinion, confirmed by a family paper which I have about me at this moment.'

I saw, now, why the appearance of the three Indian jugglers at our house had presented itself to Mr.Franklin in the light of a circumstance worth noting.
