Based in part on a popular Danish TV series, `The Killing' is a moody, character-driven detective procedural that weaves a murder mystery through a full season or more. The stories unfold through the eyes of Sarah Linden, a dedicated detective with the Seattle Police Department who at first is assigned to mentor Detective Stephen Holder, formerly of the narcotics division. While their varied, pockmarked backgrounds produce two distinct investigative styles that at times clash - she's by-the-book, he's freewheeling - the partners manage to pull together in the name of justice, even after Linden makes a decision that changes both of their lives.
