Against the backdrop of a totalitarian North Korea, one man unwillingly uncovers the truth behind series of murders, and wagers his life in the process.
Sit on a quiet hillside at dawn among the wildflowers; take a picture of a car coming up a deserted highway from the south. Simple orders for Inspector O, until he realises they have led him far, far off his department's turf and into a maelstrom of betrayal and death. North Korea's leaders are desperate to hunt down and eliminate anyone who knows too much about a series of decades-old kidnappings and murders – and Inspector O discovers too late he has been sent into the chaos.
This is a world where nothing works as it should, where the crimes of the past haunt the present, and where even the shadows are real. A corpse in Pyongyang's main hotel – the Koryo – pulls Inspector O into a confrontation of bad choices between the devils he knows and those he doesn't want to meet. A blue button on the floor of a hotel closet, an ice blue Finnish lake, and desperate efforts by the North Korean leadership set Inspector O on a journey to the edge of a reality he almost can't survive.
