“A man with no motive is a man no one suspects.”
Well, that didn’t take long, did it? As I mentioned last week, the identity of the killer (or killers) of King Joffrey, in the novels, took several volumes to ascertain for sure. In part, I think that’s because George RR Martin cast it as a fairly slight part of the plot; everyone wanted Joffrey dead, and everyone’s better off with him that way. Does it matter that much who actually did it – as long as it wasn’t Tyrion?
