The absent one a Department Q novel [WorldCat Entities]

"In The Keeper of Lost Causes, Jussi Adler-Olsen introduced Detective Carl Morck, a deeply flawed, brilliant detective newly assigned to run Department Q, the home of Copenhagen's coldest cases. The result wasn't what Morck--or readers--expected, but by the opening of Adler-Olsen's shocking, fast-paced follow-up, Morck is satisfied with the notion of picking up long-cold leads. So he's naturally intrigued when a closed case lands on his desk: A brother and sister were brutally murdered two decades earlier, and one of the suspects--part of a group of privileged boarding-school students--confessed and was convicted."
"Detective Carl Mørck investigates the twenty-year-old murders of a brother and sister whose confessed killer may actually be innocent, a case with ties to a homeless woman and powerful adversaries."
