It is one of Thóra's clients, Jónas, the owner of a spa located in a foggy, desolate, mystical area on the coast, who needs her help when he is involved in the murder of Birna, his part-time paramour and architect. As in "Last Rituals," the first book in the series, there are Icelandic myths and potential paranormal activities laced throughout the story.
In order to help Jónas, Thóra breaks into the victim's room, steals a diary, barges into homes, verbally attacks suspects and witnesses, lies, and generally engages in pretty sketchy unlawyer-like behavior. Yet, I find the character of Thóra strangely compelling and attractive.
I found some parts of the story a little muddled but wasn't sufficiently disturbed to stop reading. In general, I liked the hunt for clues and the ultimate solution, once the red herrings were sloughed off.
It's Thóra's personal story that adds considerably to the series. The side story of Thóra's 16-year-old son and his pregnant girlfriend was human, funny, and sad. Her ex-husband is a dunderheaded lummox. It's her battles to remain upright when everything is tilting against her that should put readers on her side.
(Readers who do not like stories of children in danger should give this a pass, as it begins with a heart-wrenching story of a little girl in jeopardy.)
