Yes I think that is what bothers me about The Jennifer Morgue. The nature of the twist means that it impacts Bob and Mo's character behavior. It is really clever and they play along beautifully with the twist but because of it neither of them are completely true to their behavior in other stories. Thus they feel slightly off the entire novel.

It is a good novel but I think that slight feeling of the characterization being off is what makes me rate the book below the other two. Mind you when you know why it is off it makes perfect sense but it does impact the novel.
