Black Butler Volume X

This was a Sherlock Holmes mystery.  I think I read nearly the same one in the last collection I read.  So I had a pretty fair idea of where this was going.  As a result, this story was very different from the others in this series.  It was less about the human condition and more about the story.  In a weird way, it felt like filler until it was time to go back to the demonic Ciel.
