Yikes! I hope you're wrong about that. Indeed his dad is flawed, but a murderer? There's evidence against this theory of course. For one thing, he never remarried. If his idea was to off her, he'd do so for a reason, and I cannot see how it was to his benefit to murder her.
By the way CJ, I am actually defending you as it pertains to what your characters say. I have written characters that are flawed. Of course, hatred of France would be mild compared to some of the things that they do.
