Part 3

“It is plainly hinted,” said Thorndyke, “that whoever gives the body Christian burial will stand to benefit, and the word ‘restitution’ seems to suggest a clue to the whereabouts of the jewels. Has no one thought it worth while to find out where the body is deposited?”

“But how could they?” demanded Blowgrave. “He doesn’t give the faintest clue. He talks as if his son knew where the body was. And then, you know, even supposing Silas did not take the jewels with him, there was the question, whose property were they? To begin with, they were pretty certainly stolen property, though no one knows where they came from. Then Reuben apparently got them from Silas by fraud, and Silas got them back by robbery and murder. If William had discovered them he would have had to give them up to Reuben’s sons, and yet they weren’t strictly Reuben’s property. No one had an undeniable claim to them, even if they could have found them.”

“But that is not the case now,” said Miss Blowgrave.

“No,” said Mr. Blowgrave, in answer to Thorndyke’s look of inquiry. “The position is quite clear now. Reuben’s grandson, my cousin Arthur, has died recently, and as he had no children, he has dispersed his property. The old farm-house and the bulk of his estate he has left to a nephew, but he made a small bequest to my daughter and named her as the residuary legatee. So that whatever rights Reuben had to the jewels are now vested in her, and on my death she will be Silas’s heir, too. As a matter of fact,” Mr. Blowgrave continued, “we were discussing this very question on the night of the robbery. I may as well tell you that my girl will be left pretty poorly off when I go, for there is a heavy mortgage on our property and mighty little capital. Uncle Reuben’s jewels would have made the old home secure for her if we could have laid our hands on them. However, I mustn’t take up your time with our domestic affairs.”

“Your domestic affairs are not entirely irrelevant,” said Thorndyke. “But what is it that you want me to do in the matter?”

“Well,” said Blowgrave, “my house has been robbed and my premises set fire to. The police can apparently do nothing. They say there is no clue at all unless the robbery was committed by somebody in the house, which is absurd, seeing that the servants were all engaged in putting out the fire. But I want the robber traced and punished, and I want to get the scarab back. It may be intrinsically valueless, as M. Fouquet said, but Silas’s testamentary letter seems to indicate that it had some value. At any rate, it is an heirloom, and I am loath to lose it. It seems a presumptuous thing to ask you to investigate a trumpery robbery, but I should take it as a great kindness if you would look into the matter.”

“Cases of robbery pure and simple,” replied Thorndyke, “are rather alien to my ordinary practice, but in this one there are certain curious features that seem to make an investigation worth while. Yes, Mr. Blowgrave, I will look into the case, and I have some hope that we may be able to lay our hands on the robber, in spite of the apparent absence of clues. I will ask you to leave both these letters for me to examine more minutely, and I shall probably want to make an inspection of the premises--perhaps to-morrow.”

“Whenever you like,” said Blowgrave. “I am delighted that you are willing to undertake the inquiry. I have heard so much about you from my friend Stalker, of the Griffin Life Assurance Company, for whom you have acted on several occasions.”

“Before you go,” said Thorndyke, “there is one point that we must clear up. Who is there besides yourselves that knows of the existence of the scarab and this letter and the history attaching to them?”

“I really can’t say,” replied Blowgrave. “No one has seen them but my cousin Arthur. I once showed them to him, and he may have talked about them in the family. I didn’t treat the matter as a secret.”

When our visitors had gone we discussed the bearings of the case.

“It is quite a romantic story,” said I, “and the robbery has its points of interest, but I am rather inclined to agree with the police--there is mighty little to go on.”

“There would have been less,” said Thorndyke, “if our sporting friend hadn’t been so pleased with himself. That typewritten letter was a piece of gratuitous impudence. Our gentleman overrated his security and crowed too loud.”

“I don’t see that there is much to be gleaned from the letter, all the same,” said I.

“I am sorry to hear you say that, Jervis,” he exclaimed, “because I was proposing to hand the letter over to you to examine and report on.”

“I was only referring to the superficial appearances,” I said hastily. “No doubt a detailed examination will bring something more distinctive into view.”

“I have no doubt it will,” he said, “and as there are reasons for pushing on the investigation as quickly as possible, I suggest that you get to work at once. I shall occupy myself with the old letter and the envelope.”

On this I began my examination without delay, and as a preliminary I proceeded to take a facsimile photograph of the letter by putting it in a large printing-frame with a sensitive plate and a plate of clear glass. The resulting negative showed not only the typewritten lettering, but also the watermark and wire lines of the paper, and a faint grease spot. Next I turned my attention to the lettering itself, and here I soon began to accumulate quite a number of identifiable peculiarities. The machine was apparently a Corona, fitted with the small “Elite” type, and the alignment was markedly defective. The “lower case”--or small--“a” was well below the line, although the capital “A” appeared to be correctly placed; the “u” was slightly above the line, and the small “m” was partly clogged with dirt.

Up to this point I had been careful to manipulate the letter with forceps (although it had been handled by at least three persons, to my knowledge), and I now proceeded to examine it for finger-prints. As I could detect none by mere inspection, I dusted the back of the paper with finely-powdered fuchsin, and distributed the powder by tapping the paper lightly. This brought into view quite a number of finger-prints, especially round the edges of the letter, and though most of them were very faint and shadowy, it was possible to make out the ridge pattern well enough for our purpose. Having blown off the excess of powder, I took the letter to the room where the large copying camera was set up, to photograph it before developing the finger-prints on the front. But here I found our laboratory assistant, Polton, in possession, with the sealed envelope fixed to the copying easel.

“I shan’t be a minute, sir,” said he. “The doctor wants an enlarged photograph of this seal. I’ve got the plate in.”

I waited while he made his exposure and then proceeded to take the photograph of the letter, or rather of the finger-prints on the back of it. When I had developed the negative I powdered the front of the letter and brought out several more finger-prints--mostly thumbs this time. They were a little difficult to see where they were imposed on the lettering, but, as the latter was bright blue and the fuchsin powder was red, this confusion disappeared in the photograph, in which the lettering was almost invisible while the finger-prints were more distinct than they had appeared to the eye. This completed my examination, and when I had verified the make of typewriter by reference to our album of specimens of typewriting, I left the negatives for Polton to dry and print and went down to the sitting-room to draw up my little report. I had just finished this and was speculating on what had become of Thorndyke, when I heard his quick step on the stair and a few moments later he entered with a roll of paper in his hand. This he unrolled on the table, fixing it open with one or two lead paper-weights, and I came round to inspect it, when I found it to be a sheet of the Ordnance map on the scale of twenty-five inches to the mile.

“Here is the Blowgraves’ place,” said Thorndyke, “nearly in the middle of the sheet. This is his house--Shawstead Manor--and that will probably be the outbuilding that was on fire. I take it that the house marked Dingle Farm is the one that Uncle Reuben occupied.”

“Probably,” I agreed. “But I don’t see why you wanted this map if you are going down to the place itself to-morrow.”

“The advantage of a map,” said Thorndyke, “is that you can see all over it at once and get the lie of the land well into your mind; and you can measure all distances accurately and quickly with a scale and a pair of dividers. When we go down to-morrow, we shall know our way about as well as Blowgrave himself.”

“And what use will that be?” I asked. “Where does the topography come into the case?”

“Well, Jervis,” he replied, “there is the robber, for instance; he came from somewhere and he went somewhere. A study of the map may give us a hint as to his movements. But here comes Polton ‘with the documents,’ as poor Miss Flite would say. What have you got for us, Polton?”

“They aren’t quite dry, sir,” said Polton, laying four large bromide prints on the table. “There’s the
