CloudedTruth, Sweet dreams, ispy,
These are interesting ideas, for sure, none of which had occurred to me, so thanks all around.
I was focused on PR and JR for a long time, then finally decided on BDI some years ago. Now, I keep changing my mind again as I sift and re-sort the information. Like you, ispy, I am troubled by what a smooth liar JR is, and has been for years, going back at least to his two year affair while married to Lucinda. He blamed the affair on the mistress and began dating Patsy before he broke up with her. Talk about red flags. PR was no better. Early on, I could understand weird behavior and deception related to JBR's murder if the family was covering up. IIRC, the story that that made me realize she was fine with deception well before the murder was the story about replacing JBR's puppy, Jacques and pretending it was the same dog. I mean, who does that? And then I learned there were other "you've got to be kidding" stories. What a pair.
Did PR have NPD? Is JR a covert N, and were PR's excesses a kind of hysteria in response to his controlingness? Were/Are both narcissistically disordered? And, if so, how might each of those permutations have shaped the events of that Christmas? No answers, just things I wonder about.
As I'm writing I 'm suddenly remembering something very chilling about JR. In one of the taped interviews after PR's death, the interviewer asked him something about PR and JBR - was he able to remember the happier times, or did it console him to know they were at rest - something along those lines. And he said he didn't think about them. It was a real jaw drop moment, but he didn't appear to have any awareness of that. It was as though they were a problem he simply didn't have any more. How odd that he's so visible and vocal now.
