When does Department Q return?

Department Q (Danish: Afdeling Q) is a series of ten Danish Nordic noir crime novels by author Jussi Adler-Olsen. The novels have been adapted in an ongoing series of highly successful Danish films and a forthcoming English language TV adaptation for Netflix. Despite using the same translations, the Penguin Group titled the first five novels differently in the UK and the USA.
A former top-rated detective (Goode) in Edinburgh is assigned to a new cold case. He is wracked with guilt following the attack that left a fellow policeman dead and his partner paralysed.
