A lot of the best mystery novels (and shows) are about the people and why they killed a person or persons, rather than just the action or clue searching of the crime and hunting down the killer. That Frost novel had all sorts of different crimes going on at once, but as you're reading it, you also find out that many of the people involved with each seperate crime, had many connections with the people from the other crimes in some way. For instance, while Frost was investigating a robbery at a strip club, he found the missing 15 year old girl there. The reason why she ran away from home was because she came home from school early because of a teacher's strike, and found her mom was cheating on her dad with a cop, who turned later turned up dead near an armed robbery at a pawn shop where the owner bought some stolen gold shillings from a house break-in that Frost was also investigating. There were even more things linking the cases together, even though so many of them weren't really related in any way.
Agatha Christie is also really good at being more about the people involved, as opposed to say; Conan Doyle's Sherlock Holmes stories can be which incidentally I also love.
Certainly today's mystery/detective shows are more along the lines of L&O/Bones/CSI/Criminal Minds than Colombo, McCloud & McMillan n' Wife. Dexter is my favorite modern one, largely because it takes it in a whole different direction.
That's all for mystery. Sorry, it's just my favorite form of entertainment. When A&E cancelled Nero Wolf; it's highest rated program at the time featuring multiple award winning actors/actresses in favor of much cheaper stupid reality shows; it was the only time I ever wrote to a network.
Anyhow, for the most part I also used to read o lot of silly books like George Carlin's and Chris Rock's. I would even throw Louis Theroux in there. He does documentary/biography stuff, but it is largely on sub cultures so it tends to be pretty funny. The last one I read was the Ron Burgundy book. It was alright.
Also, I've read a lot of true crime stories (although that's pretty related to mystery. Max Haines is my favorite writer there.)
A few of us at work were trading around the Star Wars books. I'm very hit or miss with sci-fi. Some of the Star Wars ones are great, some really stink and I can't get through them. I read Isaac Asimov's stuff when I was pretty young.
I'm also even more so hit or miss with horror. I'm more classic horror than modern.
I have a friend from grade school who's an author too, so I read his stuff. It's more outside what I usually read, but I like it none-the-less. There's http://www.amazon.com/Ryerson-Mr-R-W-Duder/dp/1475028741, and he also has a kids book out.
I've spent the last 12 years of my life working nights. A lot of that has been on machines that can basically run themselves. I've got a lot of reading in over the years.
How about you?
