It's too bad they didn't decide to remake the 10-episode "Series 2" that aired in Denmark. It takes place 2 years after the Rosie Larsen case. I was looking forward to AMC turning that into a single-season remake for American viewers. They are also currently filming a "Series 3" in Denmark, scheduled to air this fall.
Here's what Wikipedia has to say about Series 2:
Ten days after a female lawyer, Anne Dragsholm, has been found murdered, the head of the homicide department in Copenhagen, Lennart Brix, realises that his group is faced with a case much more complicated than it seemed at first. So, desperate for a breakthrough, he sends DI Ulrik Strange to approach former DI Sarah Lund and ask her to have a look at the case. Lund, who was demoted after the Nanna Birk Larsen case in the first series and currently works as a passport controller in Gedser in southern Denmark, is not interested at first, but quickly changes her mind, suspecting that the murder is not as straightforward as it seems, despite the forced confession of Dragsholm's husband.
Looks the BBC aired both original Danish series, presumably with subtitiles.http://www.bbc.co.uk...rammes/p00g6xvh
