I commend to teachers and senior students (especially here in NSW those doing HSC English Extension 2) a great series on the blog of UK crime fiction writer John Baker: Creating a Text. There are quite a few posts there beginning late in July and ongoing at this moment; some are from well-known writers, others from people not so well known. (I was asked to participate, but decided to sit this one out.)
I can guarantee you will find much to inspire you and much to think about.
