Watched "The Invisible Guardian" on Netflix.
Great film about a woman detective who goes back to her home town to track down a serial killer and as to face her own personal demons from her past.
Beautifully shot film. Subtitled.
Also would recommend 'The Frozen Dead' on Netflix. A short series (5 episodes) that starts with the decapitation of a horse and leads a detective back to confront his past as the realisation that an imprisoned serial killer (that he put behind bars) is somehow involved in a new set of murders. Set in magnificent scenery. Subtitled.
