The title refers to a reverend who everyone calls, out of total disrespect, Bells and Smells. But he doesn't really play that much of a role to warrant the title of the book. He's there but just in the background. He's not the killer, not the victim and just generally a dirty old man. So the title is irrelevant.

As for Falconer and Carmichael, they are the same, totally useless and behave like schoolyard kids. That is what has always bothered me by Inspector Falconer; he acts like a spoiled kid very willing to throw a pointless tantrum, behave petulantly and irrationally. How he would ever get to be an inspector is beyond me.

I disliked this.
