Down these mean streets Carl Mørck must walk... but following his trail is none too easy.
Copenhagen features prominently in Jussi Adler-Olsen's Mercy, but the author is not as given to precise locations as, say, Henning Mankell, who makes following one step behind Kurt Wallander relatively easy.
Here are some guesses, anyway...
Merete Lyngaard, the captive to whom no mercy is shown, is a member of the Danish parliament, the Folketing:
She parks her small blue Audi in Christiansberg car park:


Merete raised her eyes to look at the Royal Arsenal Museum (Tøjhus Museum), where a man in a white trench coat was photographing the building. Did he just snap a picture of her?

The extraordinary thing about these pictures, for an English visitor, is the apparant lack of security. The woman on the door to the Folketing who smilingly explained that only MPs and their guests could use the Snapstinget restaurant where Merete bumps into Daniel Hale, was the only person in uniform I saw; rather a stark contrast to fortress Downing Street, and a little surprising in light of the Mohammed cartoons.

Mørck lives on the Rønneholt estate in Allerød, about 20 miles north northwest of Copenhagen.
Armager, where Mørck is shot is a district to the south east of Copenhagen, on the way to the airport, and Vjalby Park, where the cyclist was murdered is to the west of the city, near the zoo.
