I've just finished reading this for the first time. Much giggling was involved - I *know* people like that, it's an occuptational hazard of being a scientist. I personally found King a very sympathetic character up until he started trying to pin the blame on someone specific rather than simply trying to misdirect the police - he does have a point about it being unlikely that he can convince anyone that the two deaths were accidents, especially given the way he behaves in shock afterwards.

Having started with the books where Marian is the POV character, it's interesting to see her through the eyes of the criminal. This applies to He Huffed And He Puffed, of course, but it has a different emotional tone when the deaths were accidental rather than deliberate. It's rather too easy to put myself in King's shoes...
