I read Blind Alley, which is the fifth book in the Eve Duncan series after reading book six, Countdown. Of course that was a fantastic idea . Either way, I wouldn't recommend it as this leaves you with a lot of spoilers for Blind Alley.
If you can set aside the complete unrealism that surrounds the story, it is actually quite an entertaining read. I read it a few years ago when I went to one of my suspense-phases in which I would read a lot of those book. (At the moment I'm not really in such a phase).
The characters were not the best or most sympathetic that I've encountered and the same goes for the story. Like I said, if you are looking for realistic or believable crime stories, keep looking, because you won't find it here. But if you don't mind from time to time, these aren't so bad.
