The entire Writer's Digest "Howdunit" series is oodles of fun. It's geared toward mystery writers, and is chock full of things you never knew you wanted to know. I've got the Scene of the Crime book on evidence gathering, and the writer used to do that kind of work in Georgia. Her stories about bloody murder scenes are great. She had to drive some evidence to a lab in Atlanta, and the evidence was two severed hands in a bucket of preservative. The bucket was on the floor of the front seat of her car, and she was in a hurry to get rid of them. Then she realized she'd just blown through the most notorious speed trap town in the county at 60 in a 45 mph zone. Fortunately, she assumed, the cops must have noticed the police-issue whip antennas and decided the car was on business. She was not looking forward to explaining the hands in the bucket.
True life is often so much more entertaining than fiction.
