The Guest by Agnes Ravatn
Karin and Ingve, are offered a luxury coastal home for a week. Once there they lead on that they own the said home, which in turn leads to them learning more than they intended from one of the other home-owner couples. Karin's growing anxieties highlight how isolation magnifies internal anxieties and self-doubts within a relationship. Not strictly a crime thriller but a razor sharp psychological thriller which focuses on the minutiae. Very engaging and entertaining. 4/5
