Annnika Bengtzon is a reporter and mother. She is going through her paper’s diversity drive to offer more on-line services and the print results suffer and appear to be about to suffer more. Because she is an eyewitness to a shooting at the Nobel festivities in the Stockholm City Hall, her status at the paper changes. A prominent member of the Nobel Science committee is the victim. Annika, because of her eyewitness status, is forbidden by law from writing about it. She is part of the murder investigation. Thus begins a wonderful, beautifully researched novel about the Nobel Committee, animal and biotech research, the Karolinska Institute, family tensions, children and more. Annika becomes more than a reporter on the case as there are questions that deserve and demand answers in addition to the identity of the murderer. We know her to be called “Kitten,” a skilled assassin who is soon on the trail of others, including Annika herself. There is another murderer, less professional than Kitten, who is doing in both scientists and their experiments and Annika runs into that killer as well. Thomas, her husband, is involved in a controversial government proposal that will identify persons who might commit a crime in the future, especially terrorism, and has had an affair with Sophie. Annika flirts with a rival reporter, Bosse, and feels some attraction for him but does not get into messy detail with him. A neighbor in Annika’s new neighborhood has a painting of Beatrice Cenci, a correspondent of the romantic Alfred Nobel. She inspires him, in the 19th century, to write poetry, a novel and a play, “Nemesis.” The play has had only one production, in 2005, in Stockholm, but the name lingers on and figures in Marklund’s novel. Did I fail to mention her detailed research into the life of Nobel? Then there is the crude next-door neighbor who keeps driving his Mercedes across her lawn to get to his driveway and who breaks up a dinner party by plowing up her flower garden. A novel with this much research could turn slightly or even mostly dull, but Marklund keeps the pages turning as her several plots unwind. Henning Mankell, noted Swedish novelist, calls Marklund “The Queen of Scandinavian Crime Fiction.” On the evidence of this effort, I would not argue with his judgment!
