Yes, I think I still have that old book somewhere, and I think I’ll re-read what it says too. I just remember being skeptical and suspicious about it, and being disappointed it had absolutely no clue in it of the identity of “Deep Throat.”
I thought that the book made it fairly clear that the only person that had the complete subset of the info that Deep Throat revealed was Al Haig.
I think with another 20 yrs of info and hindsight, DT was more than likely multiple people each telling what they knew or wanted reported.
