I'm similairly adicted to mysteries but I've been reading a lot of John Wyndham lately. It's SF frm the 50's and the 60's but it's not dated.
The Bell Jar (Sylvia Plath) and In Cold Blood (Truman Capote)are two of my favorite novels. Also anything by Daphne Du Maurier. Finally if you can find it Sunset Song is a classic of Scottish literature. I promise you'll soon get past the dialect.
