"Really enjoyed it, best show in ages," another person commented, as a third agreed: "Excellent Series, highly suggest it."

The official Netflix synopsis for nail-biting thriller Department Q reads: "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 Dept. 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."

All episodes of Department Q are available to stream now, exclusively on Netflix.
