Book Log 2019 #27: Into the Woods by Tana French

In 1984 Dublin, three children go missing, and in the ensuing search only one of them is found. He's in the woods, sneakers soaked with blood, and no memory of what happened. 

Jump forward to today. That boy is now a detective on the Dublin Murder Squad, and he's just been assigned a case with a number of similarities to what happened in 1984. Only his partner knows about his past, and if the higher ups learn about it he'll be taken off the case. Complicating matters is the very close relationship between the partners - they're not romantically involved, but everyone assumes they are. All of these personal and professional entanglements are pushed to the brink over the course of the investigation, with life-altering results.

This is the first of the Dublin Murder Squad series of novels, and if the others live up to this initial entry it's going to be a very good series indeed. It's one of the few books of this type that works as both a murder mystery and a psychological thriller.
