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 is 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 gray 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.
"'And under,' he cried. 'You have omitted the "and under."'
"I had thought that it meant that we were to dig, but now, of course, I saw at once that I was wrong. 'There is a cellar under this then?' I cried.
"'Yes, and as old as the house. Down here, through this door.'
"We went down a winding stone stair, and my companion, striking a match, lit a large lantern which stood on a barrel in the corner. In an instant it was obvious that we had at last come upon the true place, and that we had not been the only people to visit the spot recently.
"It had been used for the storage of wood, but the billets, which had evidently been littered over the floor, were now piled at the sides, so as to leave a clear space in the middle. In this space lay a large and heavy flagstone with a rusted iron ring in the centre to which a thick shepherd's-check muffler was attached.
"'By Jove!' cried my client. 'That's Brunton's muffler. I have seen it on him, and could swear to it. What has the villain been doing here?'
"At my suggestion a couple of the county police were summoned to be present, and I then endeavored to raise the stone by pulling on the cravat. I could only move it slightly, and it was with the aid of one of the constables that I succeeded at last in carrying it to one side. A black hole yawned beneath into which we all peered, while Musgrave, kneeling at the side, pushed down the lantern.
"A small chamber about seven feet deep and four feet square lay open to us. At one side of this was a squat, brass-bound wooden box, the lid of which was hinged upwards, with this curious old-fashioned key projecting from the lock. It was furred outside by a thick layer of dust, and damp and worms had eaten through the wood, so that a crop of livid fungi was growing on the inside of it. Several discs of metal, old coins apparently, such as I hold here, were scattered over the bottom of the box, but it contained nothing else.
"At the moment, however, we had no thought for the old chest, for our eyes were riveted upon that which crouched beside it. It was the figure of a man, clad in a suit of black, who squatted down upon him hams with his forehead sunk upon the edge of the box and his two arms thrown out on each side of it. The attitude had drawn all the stagnant blood to the face, and no man could have recognized that distorted liver-colored countenance; but his height, his dress, and his hair were all sufficient to show my client, when we had drawn the body up, that it was indeed his missing butler. He had been dead some days, but there was no wound or bruise upon his person to show how he had met his dreadful end.
