And the killer of Rebecca Schaeffer.
There’s definitely some funny business going on in that book. Books that were heavily pushed post-1947 are suspect. Much of what JD was doing for the government immediately after the war is still classified, but we do know he was high up in Intelligence.
All I recall is Chapman was holding a copy the day/night he killed Lennon. It just seems like an odd thing to take on an assassination to me. Whether it inspired him who knows. Insanity is a bit hard to follow some times.
