The Killing will conclude its first - sometimes slow, sometimes riveting - first season on Sunday.

What will go down on "Orpheus Descending?" Return to TV Fanatic after the episode airs for a review of the answer.

Meanwhile, AMC has picked up the drama for a second season, causing fans to wonder which regular will return.

At the moment, Michael Ausiello confirms that both Mireille Enos and Joel Kinnaman (above) will be back as detectives Linden and Holder, respectively. Also, Jamie Anne Allman - who portrays Mitch's sister, Terry - will play a key role, making it clear the action will remain in Seattle and the Larsens will, somehow, still be involved.
