I've been really glad that I've started focusing on this series again and am seriously considering going back to the beginning when I get caught up. This wasn't my favorite book in the series but I did really enjoy it. I really liked getting Mrs. Hudson's backstory. My main issue is that the focus was on the backstory for just a bit too long and then when the actual mystery/conclusion started rolling it was kind of crammed into the last third of the book. Despite that it was nice to see Mary and Sherlock in a bit more of a vulnerable light.
