I have never been into true crime or even fictional crime novels, but I have been reading more non-fiction recently and thought that perhaps this was a genre to check out. So, I did some Googling and came up with a few titles that are classics in the genre and were cheap on Kindle. I am currently reading this, which I went into completely blind, knowing nothing about the case.
All I can say is, "Damn!" It manages to be terrifying and saddening at the same time. Not a fun read and yet it is a page turner. More chilling than any 'horror' story I ever encountered. I guess that I would recommend it...but I wouldn't say it was 'enjoyable'.
I have also been reading Casino Royale at the same time for some light relief. My first Bond novel and it's interesting to see the difference between modern Bond and the guy in the book. I will have to go back and watch the original Casino Royale movie when I have finished.
