For those writing mystery and/or any type of suspenseful fiction, this is a fun read: Twenty Rules for Writing Detective Stories. The list at the end regarding cliche/passe techniques is important enough that all fiction writers should read them.
I particularly love #7. "There simply must be a corpse in a detective novel, and the deader the corpse the better."
Note to self: go back through manuscript and make sure bodies are dead. Really stiff. Pokeable. Maybe oozing.
