In King and Maxwell there were a couple of places where Baldacci stooped to using what I call "teenage boy" dialogue. You know, dialogue where the speaker thinks he is impressing you with his cleverness, but he is noh. Baldacci seems to have to work to not to use this kind of dialogue and his editor let him slide it in this novel.
The premise was a little far-fetched and not explained, but I don't think the history of the bad guy is really the point of these novels. The point is that Kind and Maxwell are fun and clever.
Actually in a couple of places in this one their cleverness seemed unfounded. Hmmmm. Maybe this wasn't such a good book. I admit I enjoy series. To me it is like keeping up with characters. And I enjoyed visiting again with King and Maxwell.
