Lurking in the shadows, waiting to be uncovered

I almost read the book. Søren Sveistrup's Kastanjemanden (2019). Left it a couple of hundred pages short. I didn't like it enough. It was alright and fairly interesting, but never grabbed in for a ride, like them unputdownable novels do. The story was interesting enough and serial killer fiction is a mightily good genre. I switched on to the series. And the adaptation is better than the original novel. Gripping shit, it never let go.
