I haven't read too many true crime books, but I am totally hooked on
The Black Dahlia Avenger.
A retired LA detective's father dies. The father was a brilliant, charismatic man who's children loved him despite his being strange, aloof, and secretive. When younger the father threw wild parties and went through several wives and families. As he got older the son had finally started connecting with his father and just has he felt their relationship was deepening the father simply dies of old age. In trying to get to know his father better, the son comes across an tiny, old photo album with pictures of some of the wives, some of the kids, his own (the son's) ex-wife, and Elizabeth Short. Elizabeth Short is also known as The Black Dahlia, and was the victim of one of (if not the) most brutal unsolved murders in American history. So now the son uses his detective skills to find out why Short was such an important person to his father. He researches her life and his and uncovers seriously creepy, horrific stuff about his own father, discovers horrible things happened among his family members in his own house when he was a child.
This reminds me of what I thought was the scariest part of the Communion book, when Streiber realizes that the alien visitations aren't a recent occurrence , but have been happening his whole life.
I'm about half-way through the thing and it's totally freaking me out and I can't stop reading it. Has anyone here read this one. Are there others you guys like?
