Norwegian Serial Killer Crime Mystery . . . I want more of this.

It's tight. There aren't any wasted words, loose ends, or dead-end plot twists. It's all there and it's good. Really good for what it is. I'm not a frequent mystery reader, but when it's this good I'll make an exception. And it was this good.

I can't really do anything here except spoil it. So I will end by saying that you just can't figure out who did it. Or, at least I couldn't.
