I've been trying to read a Martha Grimes novel, "The Blue Last". It's not doing it for me. Slow. A thousand seemingly irrelevant sub-plots (no doubt she'll weave them in sooner or later but I skipped a whole chapter to avoid one sub-plot I thought was stupid and pointless). A main character who seems to be the world's most dithering, inactive policeman, and whose idea of investigation is to put his friend, Lord Something-or-other, on the property (undercover) as a forelock-tugging gardener.
I talk to students about credibility in fiction - the gardener thing was the last straw. Back to the library it goes.
And thank heavens for libraries where you can try out authors before you buy!
