Oookay, I was going to make a post about Radar's clairvoyance as described in the book, but I got a bit sidetracked because the copy I borrowed from the Internet Archive has the cutest cover ever hello.
Here it is! I'm utterly in love. From left to right: Trapper, Hawkeye, and Duke.
Also, have some in-book character descriptions!
Trapper doesn't have a description so exact, because he doesn't really show his face for a while.
Eventually he comes out of his shell and is described as having dark hair, but I can't find the passage right now. Also, I should probably be doing my French homework instead of this... so not much time to go on a deep dive.
(I know, it's funny to think about how different Trapper & Hawkeye seem in comparison to their show counterparts! As I often say, it's like they got switched around. Well, because essentially they did.)
Also, just gotta call out the little nods to the book here! Trapper is holding a football - a reference, probably, to both the big football game that takes up the last third of the book, and the fact that he used to play college football and that's how he and Hawkeye met, when Hawkeye beat Trapper's team at the very last second. Hawkeye is holding cards, which is a reference to the fact that they sure love poker at the 4077th - there's a game going on at all times run by Painless Pole, that Hawkeye & co drop by occasionally. And Duke & Trapper are holding martini glasses - yes, the surgeons of the book 4077th love a good dry martini as much as the show doctors! Trapper is also holding a golf club, which is from the part of the book where he and Hawkeye leave the 4077th to operate on a general's son, and play a hell of a lot of golf as the "pro from Dover" (Hawkeye) and his friend.
