One winter seven graves

In the remote Arctic community of Inussuk, at the end of every summer, seven graves are dug before the ground freezes. As winter approaches, the question is whether there will be enough. In this first book of a series set in Greenland, the figure of David Maratse emerges, a prematurely retired police officer who intends to lead a quiet life, hunting and fishing, observing the whales and icebergs that slowly move through the fjord.
But when, while fishing, he finds the body of Prime Minister Nivi Winther's missing daughter, he becomes the main suspect and, at the same time, the investigator of Greenland's most famous murder.
