"Dept Q" refers to the fictional team of cold case investigators featured in the Danish crime thriller series, "The Keeper of Lost Causes" and its sequels. The core cast typically revolves around the cynical and troubled chief investigator, Carl Mørck, played by Nikolaj Lie Kaas. He's often paired with his quirky and resourceful assistant, Hafez el-Assad, played by Fares Fares. Further supporting characters may join and depart depending on the specific film, but the dynamic and contrasting personalities of Mørck and Assad are central to the series' appeal and the team's success in solving complex, long-dormant cases.
