Via http://onlectus.blogspot.com/2012/08/summary-on-goodreads.htmlThis is the second book by Jussi Adler-Olsen that I read. I guess I am nowa fan :-)I liked this one almost as much as I liked The keeper of loss causes (by Adler-Olsen as well). Why almost? Well, I understand that not two books are alike but one of the things that made The keeper of loss causes a success was "assistant assistant detective" Assad and his peculiarity. Although Assad was also present in this novel, his interaction wasn't as strong or as much as the previous one. Minus one point there.The gang in The absent one reminded me of The Likeness by Tana French. The two novels or the gang are nothing alike but both books are about a knit close group of friends and...well, one just made me think of the other.In The absent one detective Carl Mørck is back, sober and picking up cold-dead leads. This time, he is after the case of a brother and a sister who were brutally murdered 20 years ago. Right, how would he find any clues after 20 years? That is what makes this book exciting! His search takes him to a group of privileged sadistic friends who's hobbies include hunting and killing animals.Then there is Kimmie, a woman living on the street who holds the key to solving the case.I liked the pace, the intrigue and the plot. Adler-Olsen is a master in his genre. The book is good and it kept me hooked and reading nonstop. Not to mention that the Adler-Olsen's style of writing is truly engaging.I didn't like the little background on the group. Why were they like that? Aside from Kimmie, Adler-Olsen never explained why the rest of the group acted the way they did. I guess sometimes evil doesn't need to be fully explained and there are cases when you are born being evil or you aren't. But a little less description of the animals and their killing and a little bit more about the actual members of the gang would've been great.
