Stockholm. The dead of winter. The temperature is already well below freezing.

A young American dies, falling from a tall building. It appears to be a casual, self-inflicted death. It should be an open-and-shut case. But when Superintendent Lars Martin Johansson begins to delve beneath the layers of corruption, incompetence and violence that threaten to strangle the Stockholm police department, he uncovers a complex web of treachery, politics and espionage.

Johansson quickly realizes that there is nothing routine about this suicide as it soon takes him from domestic drama to the rotten heart of Sweden's government.
