I could go on and on about how great Nordic Noir shows are. They are a refreshing change from the American style of shows. The best are, in order, "Before We Die" (Sweden), "All The Sins" (Sweden), "Broen Bron - The Bridge" (Sweden, Denmark), "Bordertown" (Finland), "Deadwind" (Finland), "Ófærð - Trapped" (Iceland), "Rebecka Martinsson" (Sweden, first season)

I have the Millennium series queued up: "The Girl with the Dragon Tattoo", "The Girl who played with Fire", "The Girl Who Kicked the Hornets"

The only Nordic Noir book I've read is Smilla's Sense of Snow, but I can't recommend.

There are two American Nordic Noir series I recommend: "The Killing", set in Seattle and based on the Danish show "Forbrydelsen." Also "Fargo" the movie and all 4 seasons of the TV series.

It's interesting that that Fargo sensibility that the Cohen Brothers captured so well comes from the Nordic regions. Duluth Minnesota was once called the Helsinki of America.
