I think it must be a keystone of the genre of Victorian fiction for it to be slow-moving. This was an interesting and well-written novel, but it had a rather annoying repetitive nature - the same three stories were retold over and over again, each time with a new possible solution. So, while it was interesting overall, it was just not terribly engrossing. The ending certainly tied together most of the loose threads in an original and satisfying way, which was really the salvation of the entire book. Still, the pace of the book was its main downfall. Although, the structure was original and the way it all worked out was pretty surprising.
