Been watching this new series of late.... 'The Killing'. Danish crime thriller. CANNOT stress enough how much you need to watch it. Sarah Lund is our protagonist, a good one at that.
The murder investigation spans over 20 days (20 one hour episodes; that won't seem daunting once you've watch the first ten minutes). Jealous if you haven't already started it. Broadcasts each Saturday but you'll need to catch up on iPlayer first (1st one's not on there sorry! I ain't good at finding streaming links).
