"'He is gone. No one has seen him. He is not in his room. Oh, yes, he is gone—he is gone!' She fell back against the wall with shriek after shriek of laughter, while I, horrified at this sudden hysterical attack, rushed to the bell to summon help. The girl was taken to her room, still screaming and sobbing, while I made inquiries about Brunton. There was no doubt about it that he had disappeared. His bed had not been slept in; he had been seen by no one since he had retired to his room the night before; and yet it was difficult to see how he could have left the house, as both windows and doors were found to be fastened in the morning. His clothes, his watch, and even his money were in his room—but the black suit which he usually wore was missing. His slippers, too, were gone, but his boots were left behind. Where, then, could butler Brunton have gone in the night, and what could have become of him now?
"'Of course we searched the house from cellar to garret, but there was no trace of him. It is, as I have said, a labyrinth of an old house, especially the original wing, which is now practically uninhabited, but we ransacked every room and cellar without discovering the least sign of the missing man. It was incredible to me that he could have gone away leaving all his property behind him, and yet where could he be? I called in the local police, but without success. Rain had fallen on the night before, and we examined the lawn and the paths all round the house, but in vain. Matters were in this state when a new development quite drew our attention away from the original mystery.
"'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 arm-chair, 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 8ft. 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 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
