“Also, I mean, to be very specific, in the story it’s based on, Charles Augustus Milverton - has a very strange ending, where Holmes and Watson break into his house to get the papers back. And this character we’ve never seen before, from another blackmail plot, comes in and kills him. And we’ve always thought, that’s Doctor Watson editing the real story. So we decided to tell the real story. Obviously, it wasn’t a stranger who killed Milverton.”
