Fortitude is a place like nowhere else on Earth: a frontier boom-town in the wild and savage landscape of the far north. Sheriff Dan Anderssen leads a world-class search and rescue team but now finds himself investigating the shocking murder of a prominent member of the community. What’s more, he’s forced to work alongside DCI Eugene Morton, a British murder detective who’s just flown in. As they search for the killer, each of these cops find good reason to suspect and mistrust the other. And as things turn out, this murder won’t be the last.
