I am a huge fan of the old show "All Creatures Great and Small". I have read all of Herriot's books, and have seen every episode of the show, including the specials. (They were all on Netflix). I used to watch the show as a kid, and as an adult, I was happy to find them on Netflix, so I watched the whole thing beginning to end (not all at once!). I was surprised to learn that Christopher Timothy had written a book - and given the title - I thought it would be ALL about his experience on the show.
Not really. Very little of this book actually talks about the show itself. There are a few anecdotes about filming certain scenes or about how he got the part, but mostly he jumps around talking about his acting career, and various other things. There's no balance to the book or story (if there is one), and only fans of the show would find it mildly interesting.
It was published in 1979, and I got one of the first editions (I uploaded the pictures here). If I read it correctly, he wrote this after season 2. He doesn't go into a whole lot of detail with his relationship with Carol Drinkwater, which I really wanted to hear about. I got this for pennies here, and if I had paid any more I might be annoyed. It's not that great of a book, but I kind of liked it if only for curiousity sake.
