The body of a foreign student is discovered in the streets of the down at heel city of Besźel. Cases like this are run of the mill for Inspector Tyador Borlú of the Extreme Crime Squad - until his investigations uncover evidence that the dead girl had come from another city called Ul Qoma. But the relationship between the two cities defies comprehension and will challenge everything Borlú holds dear.
The series, described as a dark adult drama which mixes multiple genres, is set in the sleepy Arctic town of Fortitude, whose close-knit community is shaken up by the brutal murder of a British research scientist. Leading the investigation is local Sheriff Dan Anderssen, who is joined by British detective DCI Milton Caldwell.
