From Acorn TV:

Decades ago, teenagers Olaf and Alice disappeared from the Dutch village of Schouwendam without a trace. Then an unknown man suddenly turns up in town with no memories but a clear resemblance to Olaf. The residents are forced to confront the mysteries of the past, but who is lying and who is telling the truth? As new fatalities occur, the community is riven with fear in this Dutch-language drama.

From Acorn TV you can stream this 10 episode one season Dutch mystery drama. Each episode lasts about 45 minutes. English subtitles. Now and then the characters speak English.

As this mystery proceeds, one by one residents of this small town are being murdered. Meanwhile the newly appeared “Olaf” who is suffering from amnesia keeps trying to discover if he really is Olaf.

As a subplot the young policeman Pim must contend with his wife and newborn infant because his wife is suffering from serious postpartum depression.  This becomes relevant to the mystery solution.

To help Pim a new superior  woman detective Karlijn van Andel  arrives on the scene.  Her personal story also becomes relevant to the plot.

Be prepared for a very surprising final episode.

Well worth your time.
