I sometimes imagine there is a clerk behind a desk situated between the brain and the mouth. It is his job to examine utterances on their way out, and stamp them with approval or send them back for reconsideration. If such a clerk exists, mine must be very harried and overworked; and on occasion he puts his head down on the desk in despair, letting things pass without so much as a second glance.
I am not sure but I think this is my favourite book of the series so far.
It is such a thoughtful book. And Lady Trent is one kick-ass main character.
