I have always been a lazy reader, seldom reading the works one should, but I would recommend Wodehouse and Ngaio Marsh, both of whom I was reading at that age. Wodehouse because he's uncomplicated fun, but still manages to gently lampoon his subjects, and Marsh because her detective novels are primarily a vehicle for conveying her passion for the theatre, and for Shakespeare in particular, and reading them persuaded me that the Bard was worth looking into.
