I really enjoy this series. It's not amazing literature, but still fast-paced fun. Strangely enough the BKA seems to work beyond German borders more than within. But hey, when I begin to think that things might be just a tad unrealistic I repeat to myself that it's just a book, I should really just relax. The characters are nice, even the dickish Sneijder. The women are very competent and the amount of personal crap that interferes with the actual investigation is kept to an absolute minimum. I very much like that. Overall an enjoyable thriller series with very sick killers and twists and turns.
