Lucifer's Tears (Inspector Vaara Series #2)

Inspector Kari Vaara has left the Arctic Circle and returned- reluctantly-to Helsinki, where headaches and sleeplessness plague him. But he must work through the pain. He has two cases on his plate: the brutal murder of a Russian businessman's wife, and-more secretively-an investigation into an elderly Finnish national hero who may have played a darker role in World War II than the public knows. Vaara's past has turned him into a haunted man. The questions he's asking now may turn him into a hunted man as well...
