As I said, my brother is a sociopath, officially diagnosed back in the 60's. If you were to meet him, you would think he's the nicest most kind person you've ever met. He has a silver tongue and a heart of stone. He's a pathological liar. He cannot be trusted by anybody who has known him since he was a child. Burke may be innocent, but the parents' actions were vaguely familiar. If John had killed her, Patsey would have been outraged. If Patsey had done it, John would be outraged. The only thing that would have brought them to act this way and hang together until her death would have been Burke...........
The evidence all points to an intruder.
Why is it so hard to believe that she was killed by an intruder?
