The Absent One by Jussi Adler Olsen
In The Keeper of Lost Causes, American audiences were finally introduced to Copenhagen’s Detective Carl Mørck and his creator, #1 international bestselling author Jussi Adler-Olsen. Now, Mørck is back. He’s settled into Department Q and is ready to take on another cold case. This time, it’s the brutal double-murder of a brother and sister two decades earlier. One of the suspects confessed and is serving time, but it’s clear to Mørck that all is not what it seems. Kimmie, a homeless woman with secrets involving certain powerful individuals, could hold the key—if Mørck can track her down before they do.
