DCI Carl Morck is a brilliant cop but a terrible colleague. His razor-sharp sarcasm has made him no friends in Edinburgh police. After a shooting that leaves a young PC dead, and his partner paralysed, he finds himself exiled to the basement and the sole member of Department Q; a newly formed cold case unit. The department is a PR stunt, there to distract the public from the failures of an under-resourced, failing police force that is glad to see the back of him. But more by accident than design, Carl starts to build a gang of waifs and strays who have everything to prove. So, when the stone-cold trail of a prominent civil servant who disappeared several years ago starts to heat up, Carl is back doing what he does best - rattling cages and refusing to take no for an answer.
