Shadows from the past have a long reach. Invited as guests on a cruise ship in the southern hemisphere, retired Constable David Maratse and Sergeant Petra Jensen find themselves embroiled in a foreign plot to destabilise the Greenland government. As the dust settles following the fallout of the Danish prison court case, Maratse is encouraged by Petra to accept an invitation to join an adventure cruise ship in Antarctica – a chance for them both to heal. But foreign powers are moving in the shadows, waiting to strike. And one player in particular has Maratse in his sights, forcing the retired police constable to confront his old nemesis: The Chinese man. Isolated at sea, Maratse's only advantage is his understanding of ice. Whale Heart is the fifth book in the Greenland Crime series, reuniting readers with familiar characters and threads, while introducing a shadowy antagonist from Maratse's past.
