"A full-throttle thriller in the tradition of classic Stieg Larsson" --A.J. Finn, author of The Woman in the Window

From Søren Sveistrup, creator of the hit television show, The Killing--a stylish and atmospheric thriller that follows the race to find a serial killer terrorizing Copenhagen.

A psychopath is terrorizing Copenhagen.

His calling card is a "chestnut man"--a handmade doll made of matchsticks and two chestnuts--which he leaves at each bloody crime scene.

Examining the dolls, forensics makes a shocking discovery--a fingerprint belonging to a young girl, a government minister's daughter who had been kidnapped and murdered a year ago.

A tragic coincidence--or something more twisted?

To save innocent lives, a pair of detectives must put aside their differences to piece together the Chestnut Man's gruesome clues.

Because it's clear that the madman is on a mission that is far from over.

And no one is safe.
