So, I've had "Behold a Pale Horse" on my to-read list for a while and finally started it last night. I'm almost halfway through - can't put it down. I mean, a lot of the info has been exposed to (and awakened) the general public in recent years (in large part because of Cooper's work, I imagine) but to have the detail in his words and the source documentation all in front of your eyes, it's been mindblowing all over again...
RIP, Bill. You are a hero and shall not be forgotten.
