Posting on the phone, so forgive any issues!
Just finished the book while sitting by the pool. Wow, it's hot out here. I should have finished this yesterday, but the intricacies of the  early 1800's legal system in England couldn't stand up to kids and a holiday.
The book rounded out with all of the meat of the mystery at the end and another allusion. This guest appearance was made by Emma. It was woven in skillfully and didn't strike me as being so heavy-handed as the previous. Maybe because it came in the resolution rather than during the action.
Alas, now that it is over I will have to sweat it out in boredom.
