Really entertaining. In the beginning the focus is split and I started to wonder when the two stories would come together, but the payoff when they did was pretty great. Dark and twisted, totally intense mystery. Loved how it was finally figured out. So many well-drawn characters and spooky pasts to think about. Very cool.
The title is a bit of a misnomer. That person exists, but the tattoo is very little to the point. But that may have been picked by the publisher as apparently Larsson died shortly after turning in this manuscript (and two others).
