This is the second of Theorin's novels that I have read, and "The Darkest Room" is just as good as "Echoes from the Dead". It's a very atmospheric murder mystery with slight supernatural overtones, which never swamp the sense of real-life menace or go really over-the-top. The novel follows two main parallel stories, one outlining the history of Eel Point and its two lighthouses, and the other following the trials of a family who have lived with tragedy and who want to make a new life out of the city. There is also a great sub-plot regarding a couple of ne'er-do-well burglars.
The characters are well drawn, the twists plentiful, and the denouement a real surprise! On several occasions I had myself convinced that I had the mystery solved only to find that I was barking up completely the wrong tree.
What struck me most about this novel is its portrayal of the awful weather that the characters have to put up with and its effect on their everyday lives. We're talking blizzards, hailstorms, awful driving rain and bitter cold. We're given a real sense of the weather as an impersonal and yet inimical force in the story, and in some cases it's almost a character in itself.
It's all very well done, and all the disparate elements of the novel come together strongly at the end to make for a very satisfying read. I understand from the blurb that Johan Theorin is planning this series as a quartet, and I for one can't wait for the next installment.
