Part 22

“‘For two days Rachel Howells had been so ill, sometimes delirious, sometimes hysterical, that a nurse had been employed to sit up with her at night. On the third night after Brunton’s disappearance, the nurse, finding her patient sleeping nicely, had dropped into a nap in the armchair, when she woke in the early morning to find the bed empty, the window open, and no signs of the invalid. I was instantly aroused, and, with the two footmen, started off at once in search of the missing girl. It was not difficult to tell the direction which she had taken, for, starting from under her window, we could follow her footmarks easily across the lawn to the edge of the mere, where they vanished close to the gravel path which leads out of the grounds. The lake there is eight feet deep, and you can imagine our feelings when we saw that the trail of the poor demented girl came to an end at the edge of it. “‘Of course, we had the drags at once, and set to work to recover the remains, but no trace of the body could we find. On the other hand, we brought to the surface an object of a most unexpected kind. It was a linen bag which contained within it a mass of old rusted and discoloured metal and several dull-coloured pieces of pebble or glass. This strange find was all that we could get from the mere, and, although we made every possible search and inquiry yesterday, we know nothing of the fate either of Rachel Howells or of Richard Brunton. The county police are at their wits’ end, and I have come up to you as a last resource.’ “You can imagine, Watson, with what eagerness I listened to this extraordinary sequence of events, and endeavoured to piece them together, and to devise some common thread upon which they might all hang. The butler was gone. The maid was gone. The maid had loved the butler, but had afterwards had cause to hate him. She was of Welsh blood, fiery and passionate. She had been terribly excited immediately after his disappearance. She had flung into the lake a bag containing some curious contents. These were all factors which had to be taken into consideration, and yet none of them got quite to the heart of the matter. What was the starting-point of this chain of events? There lay the end of this tangled line. “‘I must see that paper, Musgrave,’ said I, ‘which this butler of yours thought it worth his while to consult, even at the risk of the loss of his place.’ “‘It is rather an absurd business, this ritual of ours,’ he answered. ‘But it has at least the saving grace of antiquity to excuse it. I have a copy of the questions and answers here if you care to run your eye over them.’ “He handed me the very paper which I have here, Watson, and this is the strange catechism to which each Musgrave had to submit when he came to man’s estate. I will read you the questions and answers as they stand. “‘Whose was it?’ “‘His who is gone.’ “‘Who shall have it?’ “‘He who will come.’ “‘Where was the sun?’ “‘Over the oak.’ “‘Where was the shadow?’ “‘Under the elm.’ “How was it stepped?’ “‘North by ten and by ten, east by five and by five, south by two and by two, west by one and by one, and so under.’ “‘What shall we give for it?’ “‘All that is ours.’ “‘Why should we give it?’ “‘For the sake of the trust.’ “‘The original has no date, but is in the spelling of the middle of the seventeenth century,’ remarked Musgrave. ‘I am afraid, however, that it can be of little help to you in solving this mystery.’ “‘At least,’ said I, ‘it gives us another mystery, and one which is even more interesting than the first. It may be that the solution of the one may prove to be the solution of the other. You will excuse me, Musgrave, if I say that your butler appears to me to have been a very clever man, and to have had a clearer insight than ten generations of his masters.’ “‘I hardly follow you,’ said Musgrave. ‘The paper seems to me to be of no practical importance.’ “‘But to me it seems immensely practical, and I fancy that Brunton took the same view. He had probably seen it before that night on which you caught him.’ “‘It is very possible. We took no pains to hide it.’ “‘He simply wished, I should imagine, to refresh his memory upon that last occasion. He had, as I understand, some sort of map or chart which he was comparing with the manuscript, and which he thrust into his pocket when you appeared.’ “‘That is true. But what could he have to do with this old family custom of ours, and what does this rigmarole mean?’ “‘I don’t think that we should have much difficulty in determining that,’ said I; ‘with your permission we will take the first train down to Sussex, and go a little more deeply into the matter upon the spot.’ “The same afternoon saw us both at Hurlstone. Possibly you have seen pictures and read descriptions of the famous old building, so I will confine my account of it to saying that it is built in the shape of an L, the long arm being the more modern portion, and the shorter the ancient nucleus, from which the other had developed. Over the low, heavily-lintelled door, in the centre of this old part, is chiseled the date, 1607, but experts are agreed that the beams and stonework are really much older than this. The enormously thick walls and tiny windows of this part had in the last century driven the family into building the new wing, and the old one was used now as a storehouse and a cellar, when it was used at all. A splendid park with fine old timber surrounds the house, and the lake, to which my client had referred, lay close to the avenue, about two hundred yards from the building. “I was already firmly convinced, Watson, that there were not three separate mysteries here, but one only, and that if I could read the Musgrave Ritual aright I should hold in my hand the clue which would lead me to the truth concerning both the butler Brunton and the maid Howells. To that then I turned all my energies. Why should this servant be so anxious to master this old formula? Evidently because he saw something in it which had escaped all those generations of country squires, and from which he expected some personal advantage. What was it then, and how had it affected his fate? “It was perfectly obvious to me, on reading the Ritual, that the measurements must refer to some spot to which the rest of the document alluded, and that if we could find that spot, we should be in a fair way towards finding what the secret was which the old Musgraves had thought it necessary to embalm in so curious a fashion. There were two guides given us to start with, an oak and an elm. As to the oak there could be no question at all. Right in front of the house, upon the left-hand side of the drive, there stood a patriarch among oaks, one of the most magnificent trees that I have ever seen. “‘That was there when your Ritual was drawn up,’ said I, as we drove past it. “‘It was there at the Norman Conquest in all probability,’ he answered. ‘It has a girth of twenty-three feet.’ “‘Have you any old elms?’ I asked. “‘There used to be a very old one over yonder but it was struck by lightning ten years ago, and we cut down the stump.’ “‘You can see where it used to be?’ “‘Oh, yes.’ “‘There are no other elms?’ “‘No old ones, but plenty of beeches.’ “‘I should like to see where it grew.’ “We had driven up in a dog-cart, and my client led me away at once, without our entering the house, to the scar on the lawn where the elm had stood. It was nearly midway between the oak and the house. My investigation seemed to be progressing. “‘I suppose it is impossible to find out how high the elm was?’ I asked. “‘I can give you it at once. It was sixty-four feet.’ “‘How do you come to know it?’ I asked, in surprise. “‘When my old tutor used to give me an exercise in trigonometry, it always took the shape of measuring heights. When I was a lad I worked out every tree and building in the estate.’ “This was an unexpected piece of luck. My data were coming more quickly than I could have reasonably hoped. “‘Tell me,’ I asked, ‘did your butler ever ask you such a question?’ “Reginald Musgrave looked at me in astonishment. ‘Now that you call it to my mind,’ he answered, ‘Brunton _did_ ask me about the height of the tree some months ago, in connection with some little argument with the groom.’ “This was excellent news, Watson, for it showed me that I was on the right road. I looked up at the sun. It was low in the heavens, and I calculated that in less than an hour it would lie just above the topmost branches of the old oak. One condition mentioned in the Ritual would then be fulfilled. And the shadow of the elm must mean the farther end of the shadow, otherwise the trunk would have been chosen as the guide. I had, then, to find where the far end of the shadow would fall when the sun was just clear of the oak.” “That must have been difficult, Holmes, when the elm was no longer there.” “Well, at least I knew that if Brunton could do it, I could also. Besides, there was no real difficulty. I went with Musgrave to his study and whittled myself this peg, to which I tied this long string with a knot at each yard. Then I took two lengths of a fishing-rod, which came to just six feet, and I went back with my client to where the elm had been. The sun was just grazing the top of the oak. I fastened the rod on end, marked out the direction of the shadow, and measured it. It was nine feet in length. “Of course the calculation now was a simple one. If a rod of six feet threw a shadow of nine, a tree of sixty-four feet would throw one of ninety-six, and the line of the one would of course be the line of the other. I measured out the distance, which brought me almost to the wall of the house, and I thrust a peg into the spot. You can imagine my exultation, Watson, when within two inches of my peg I saw a conical depression in the ground. I knew that it was the mark made by Brunton in his measurements, and that I was still upon his trail. “From this starting-point I proceeded to step, having first taken the cardinal points by my pocket-compass. Ten steps with each foot took me along parallel with the wall of the house, and again I marked my spot with a peg. Then I carefully paced off five to the east and two to the south. It brought me to the very threshold of the old door. Two steps to the west meant now that I was to go two paces down the stone-flagged passage, and this was the place indicated by the Ritual. “Never have I felt such a cold chill of disappointment, Watson. For a moment it seemed to me that there must be some radical mistake in my calculations. The setting sun shone full upon the passage floor, and I could see that the old, foot-worn grey stones with which it was paved were firmly cemented together, and had certainly not been moved for many a long year. Brunton had not been at work here. I tapped upon the floor, but it sounded the same all over, and there was no sign of any crack or crevice. But, fortunately, Musgrave, who had begun to appreciate the meaning of my proceedings, and who was now as excited as myself, took out his manuscript to check my calculation.
