Spoiler alert. Anyone reading Outrage hoping to see a "man bites dog" (i.e., rare and unusual) case of a woman found to be falsely crying rape is going to be disappointed. It's going to be a let down for someone who feels that victims should just get over it. The outrage that is presented clearly in the story is that rapists very often get light sentences or are often not punished at all, and that victims are seen as to blame, shamed, and expected to quickly put the terrible experience behind.
Seen in this light, Outrage may not seem unusual enough for the tastes of some readers, and of course rape is a more complex crime than can be addressed in a couple-hundred-page novel, and yet this is an interesting enough procedural, and serves well to expand the series to include the usually-peripheral character Elinborg as well as give us a better view not only of her skill as a police investigator, but of her interests and family life. Meanwhile throughout, we are given hints of the growing mystery of Erlender's disappearance. Outrage leaves you wanting to know more--to plunge into the next book that focuses on Sigurdur Oli, and wonder all the more what Erlender is up to.
