programme?'
'Your uncle's mania for buying things at second-hand was broken in three instances so far as I have been able to learn from a scrutiny of these accounts. About four years ago he purchased a new book from Denny and Co., the well-known booksellers of the Strand. Denny and Co. deal only in new books. Is there any comparatively new volume in the library?'
'Not one.'
'Are you sure of that?'
'Oh, quite; I searched all the literature in the house. What is the name of the volume he bought?'
'That I cannot decipher. The initial letter looks like "M", but the rest is a mere wavy line. I see, however, that it cost twelve-and-sixpence, while the cost of carriage by parcel post was sixpence, which shows it weighed something under four pounds. This, with the price of the book, induces me to think that it was a scientific work, printed on heavy paper and illustrated.'
'I know nothing of it,' said the earl.
'The third account is for wallpaper; twenty-seven rolls of an expensive wallpaper, and twenty-seven rolls of a cheap paper, the latter being just half the price of the former. This wallpaper seems to have been supplied by a tradesman in the station road in the village of Chizelrigg.'
'There's your wallpaper,' cried the youth, waving his hand; 'he was going to paper the whole house, Higgins told me, but got tired after he had finished the library, which took him nearly a year to accomplish, for he worked at it very intermittently, mixing the paste in the boudoir, a pailful at a time as he needed it. It was a scandalous thing to do, for underneath the paper is the most exquisite oak panelling, very plain, but very rich in colour.'
I rose and examined the paper on the wall. It was dark brown, and answered the description of the expensive paper on the bill.
'What became of the cheap paper?' I asked.
'I don't know.'
'I think,' said I, 'we are on the track of the mystery. I believe that paper covers a sliding panel or concealed door.'
'It is very likely,' replied the earl. 'I intended to have the paper off, but I had no money to pay a workman, and I am not so industrious as was my uncle. What is your remaining account?'
'The last also pertains to paper, but comes from a firm in Budge Row, London, E.C. He has had, it seems, a thousand sheets of it, and it appears to have been frightfully expensive. This bill is also illegible, but I take it a thousand sheets were supplied, although of course it may have been a thousand quires, which would be a little more reasonable for the price charged, or a thousand reams, which would be exceedingly cheap.'
'I don't know anything about that. Let's turn on Higgins.'
Higgins knew nothing of this last order of paper either. The wallpaper mystery he at once cleared up. Apparently the old earl had discovered by experiment that the heavy, expensive wallpaper would not stick to the glossy panelling, so he had purchased a cheaper paper, and had pasted that on first. Higgins said he had gone all over the panelling with a yellowish-white paper, and after that was dry, he pasted over it the more expensive rolls.
'But,' I objected, 'the two papers were bought and delivered at the same time; therefore, he could not have found by experiment that the heavy paper would not stick.'
'I don't think there is much in that,' commented the earl; 'the heavy paper may have been bought first, and found to be unsuitable, and then the coarse, cheap paper bought afterwards. The bill merely shows that the account was sent in on that date. Indeed, as the village of Chizelrigg is but a few miles away, it would have been quite possible for my uncle to have bought the heavy paper in the morning, tried it, and in the afternoon sent for the commoner lot; but in any case, the bill would not have been presented until months after the order, and the two purchases were thus lumped together.'
I was forced to confess that this seemed reasonable.
Now, about the book ordered from Denny's. Did Higgins remember anything regarding it? It came four years ago.
Ah, yes, Higgins did; he remembered it very well indeed. He had come in one morning with the earl's tea, and the old man was sitting up in bed reading his volume with such interest that he was unaware of Higgins's knock, and Higgins himself, being a little hard of hearing, took for granted the command to enter. The earl hastily thrust the book under the pillow, alongside the revolvers, and rated Higgins in a most cruel way for entering the room before getting permission to do so. He had never seen the earl so angry before, and he laid it all to this book. It was after the book had come that the forge had been erected and the anvil bought. Higgins never saw the book again, but one morning, six months before the earl died, Higgins, in raking out the cinders of the forge, found what he supposed was a portion of the book's cover. He believed his master had burnt the volume.
Having dismissed Higgins, I said to the earl,—
'The first thing to be done is to enclose this bill to Denny and Co., booksellers, Strand. Tell them you have lost the volume, and ask them to send another. There is likely someone in the shop who can decipher the illegible writing. I am certain the book will give us a clue. Now, I shall write to Braun and Sons, Budge Row. This is evidently a French company; in fact, the name as connected with paper-making runs in my mind, although I cannot at this moment place it. I shall ask them the use of this paper that they furnished to the late earl.'
This was done accordingly, and now, as we thought, until the answers came, we were two men out of work. Yet the next morning, I am pleased to say, and I have always rather plumed myself on the fact, I solved the mystery before replies were received from London. Of course, both the book and the answer of the paper agents, by putting two and two together, would have given us the key.
After breakfast, I strolled somewhat aimlessly into the library, whose floor was now strewn merely with brown wrapping paper, bits of string, and all that. As I shuffled among this with my feet, as if tossing aside dead autumn leaves in a forest path, my attention was suddenly drawn to several squares of paper, unwrinkled, and never used for wrapping. These sheets seemed to me strangely familiar. I picked one of them up, and at once the significance of the name Braun and Sons occurred to me. They are paper makers in France, who produce a smooth, very tough sheet, which, dear as it is, proves infinitely cheap compared with the fine vellum it deposed in a certain branch of industry. In Paris, years before, these sheets had given me the knowledge of how a gang of thieves disposed of their gold without melting it. The paper was used instead of vellum in the rougher processes of manufacturing gold-leaf. It stood the constant beating of the hammer nearly as well as the vellum, and here at once there flashed on me the secret of the old man's midnight anvil work. He was transforming his sovereigns into gold-leaf, which must have been of a rude, thick kind, because to produce the gold-leaf of commerce he still needed the vellum as well as a 'clutch' and other machinery, of which we had found no trace.
'My lord,' I called to my assistant; he was at the other end of the room; 'I wish to test a theory on the anvil of your own fresh common sense.'
'Hammer away,' replied the earl, approaching me with his usual good-natured, jocular expression.
'I eliminate the safe from our investigations because it was purchased thirteen years ago, but the buying of the book, of wall covering, of this tough paper from France, all group themselves into a set of incidents occurring within the same month as the purchase of the anvil and the building of the forge; therefore, I think they are related to one another. Here are some sheets of paper he got from Budge Row. Have you ever seen anything like it? Try to tear this sample.'
'It's reasonably tough,'
