I read books that sometimes irritate me because they contain cheap tricks, but nothing causes me to grit my teeth and throw the book across the room than when it's a mystery with cheap writing tricks. What are some of these "don't use ideas"? Ah, let me count the ways. Sorry, wrong analogy.
Don't have a protagonist, which is usually a woman, insert herself into a dangerous situation when she could call 911. How many stupid people are there in the literary world?
Don't leave the reader guessing about what the hero finds. A clue, a piece of evidence, whatever, should be shared with the reader when the character finds it.
Don't make dialogue boring, unreal, filled with background information. Have you ever become irate when one character explains something to another that the second person should know? I don't like it when one CSI person tells someone running a test all the steps. Surely the one running the test would know what to do.
Don't make the police appear stupid or dumb. Law enforcement officers should be realistic, not buffoons. Yes, they can make mistakes and actually appear flawed as we all are, but they should be intelligent enough to be on the force.
Just a few of my "don't dos," but I'll have more another time.
