that he was gone. She was in such a state that another servant was posted to sit up with her at night. Eventually, however, the guarding servant nodded off one night, and the hysterical Rachel Howells escaped through a window. Her footprints led to the edge of the mere, and ended there. Musgrave had the mere dredged, but only a sack containing some rusty, mangled bits of metal, and some coloured stones or glass were found. Rachel Howells was never heard from again. Holmes looked upon the case not as three mysteries, but as one. He considered the riddle of the ritual. It was a meaningless, absurd tradition to Musgrave, and apparently to all his ancestors going back more than two centuries, but Holmes – and Brunton, too, Holmes suspected – saw it as something very different. He quickly realized that it was a set of instructions for finding something. Ascertaining the height of the oak, which was still standing, and the position of the elm, which was now gone, Holmes performed a few calculations and paced out the route to whatever awaited him, with Musgrave now eagerly following him. It was quite instructive to Holmes that Brunton had recently asked about the old elm tree's height as well, and that he was apparently quite intelligent. The two men found themselves inside a doorway, momentarily disappointed, until they realized that there was the last instruction, "and so under". There was a cellar under where they were standing, as old as the house. Finding their way into it, they saw that the floor had been cleared to expose a stone slab with an iron ring on it with Brunton's muffler tied to it. Holmes thought it wise to bring the police in at this point. He and a burly Sussex policeman managed to lift the slab off the little hole that it was covering, and inside, they found an empty, rotten chest, and Brunton, who had been dead for several days. There were no marks on him. He had likely suffocated. Holmes then put everything together for his rather shocked client. Brunton had deduced the ritual's meaning, at least insofar as it led to something valuable. He had determined the elm tree's height by asking his master, had paced out the instructions – and Holmes had later even found a peg hole in the lawn made by Brunton – had found
