My first taste of Lars Kepler, I found The Rabbit Hunter a dark and grisly novel, too much so at times. I mostly enjoyed the plot, but it did get sidetracked from time to time, with issues not necessary for the story. The characters held my interest, but the two main ones were thinly sketched. Maybe because they’ve been around through several books. More effort was spent on the chef and his son, and the killer.
The pace moved fairly slow in the beginning, probably because either the authors or the translator (English translation) wrote too much passive, not active. It picked up as the story progressed. The ending was an obvious plug to try to get you to read the next book.
I always find it fascinating when two or more writers collaborate. This husband and wife team work together seamlessly.
