Well, I probably read more than these two, but they are the ones I remember and want to recommend. Both books were birthday presents from my clever children.
Jørn Lier Horst, Dregs (2011).
The sixth in the Norwegian series about Chief Inspector Wisting, but the first that has been translated into Danish and English. Nice, traditional police procedural.
Jo Nesbø, The Leopard (2011).
There is probably no need to introduce Harry Hole to my faithful readers, but even though I recommend this one for its exciting plot, I´ll have to warn you that this book is not for the faint.
