After reading a lot of the graphic novels (and having vague fond memories of the 1970s TV series ;-), I finally decided to try the original prose novel. I suspect this isn't quite it, though; the Wikipedia notes that "Beginning in 1959, the books were extensively revised, largely to eliminate racist stereotypes. The books were also written in a simpler style in an attempt to compete with television." While I'm definitely in favor of eliminating racist stereotypes, I'd be very interested in reading the original version. This one seems a bit choppy, and one of the characters came across as a possible villain; at least, his timing seemed highly suspect. Perhaps the explanation was dropped in the rewrite.
Overall, I had fun with the book, apart from the choppiness, and may well read more, but they're not at the top of my list.
