The blurb reads: A luxury yacht arrives in Reykjavik harbour with nobody on board. What has happened to the crew, and to the family who were on board when it left Lisbon? Thora Gudmundsdottir is hired by the young father’s parents to investigate, and is soon drawn deeper into the mystery. What should she make of the rumours saying that the vessel was cursed, especially given that when she boards the yacht she thinks she sees one of the missing twins? Where is Karitas, the glamorous young wife of the yacht’s former owner? And whose is the body that has washed up further along the shore? The most chilling novel yet from Yrsa Sigurdardottír, an international bestseller at the height of her powers. (Source: Hodder & Stoughton)
My review is here.
Although it was not my preferred choice, I must congratulate Yrsa for having won between a strong set of contenders.
A Crime is Afoot 
I will read this book, and I will read The Hunting Dogs due to your good review and also The Hummingbird, due to positive reviews, including Norman’s.
I am trying to find out why this book won since I haven’t seen enthusiasm for it on crime fiction blogs. There may be elements that the judges found very compelling. I just wish there was an explanation somewhere.
