It gets pretty engrossing, although some of the threads seem a bit disconnected - in particular the old events in Hedinsfjörður which Ari Thor starts investigating in an idle moment during a medical lockdown (many years pre Covid!) don't really seem to be connected to the goings on in Reykjavik with politicians drugs murder and child abduction.

Ultimately perhaps the link is that all of the stories concern more or less broken people and their relationships.

Having said that it is a good read and keeps you more or less guessing over some of the twists and turns as the cases evolve.
