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.
