Fiction by Martha Grimes.
This was a story about a twelve-year-old girl in a small town trying to solve an old murder case. I didn't really like it.
It moved too slowly and I almost gave up on it several times, but I really wanted to find out who the murderer was, so I did read the whole thing. The ending wasn't too great either, though.
I'm not giving it the full thumbs-down because it did (apparently) interest me enough to make me finish it. But this one I do not recommend.
