Query: A Very disappointing mystery

I can't really judge if this is an accurate medieval setting, although it is a very vivid one. The problem here is the plot. At the end of the book, I am left completely baffled by the motives of the main actors. I won't discuss it in any detail, since I don't want to spoil the plot, but they must have been relatively stupid since they could have accomplished their purposes in a simple and straightforward way that would have avoided a lot of grief. A friend of mine would roll her eyes at this point and tell me that their motive is simple: if they behaved sensibly, there wouldn't be a plot. Silly me.
