Tomorrow, the sun will rise for the first time in 40 days. Thirty minutes of daylight will herald the end of the polar night in Kautokeino, a small village in northern Norway, home to the indigenous Sami people. But in the last hours of darkness, a precious artifact is stolen: an ancient Sami drum. The most important piece in the museum's collection, it was due to go on tour with a UN exhibition in a few short weeks. Hours later, a man is murdered. Mattis, one of the last Sami reindeer herders, is found dead in his gumpy. Are the two crimes connected?
