I read very little true crime. I prefer fictional crime even if it's based on real crimes. I am not sure why but I think it's because a fiction writer leaves out the boring parts. Or at least a good one does. And the story also seems more remote, less scary.
Megan and Phil and even Josh read a ton of true crime though. Phil just read SAVAGE HARVEST about the gory details of Michael Rockefeller in New Guinea with a tribe of cannibals. Ugh!
I have read a few good ones though and I would chose IN COLD BLOOD as my favorite. Capote changed the notion of reportage with this one and the Clutter family will always haunt me.
What is your favorite true crime book.
