After witnessing a mysterious murder, Icelandic lawyer Kristin finds herself holding the first clues in her hands to uncover the “Tears of the Wolf”—a legendary stash of Nazi diamonds. Joined by her partner Steve and their friend Einar, the trio embarks on a perilous hunt through encoded WWII artifacts, cryptic Enigma machine ciphers, and lost sheets of musical notes. As the trio rushes from rural Iceland to a museum heist in Finland, and then onward to Germany, they're pitted against brutal mercenaries—and the mysterious and deadly assassin Thomas, who proves to be a ruthless adversary in his hunt for “The Tears.” Twists and betrayals abound as the adventure leads to a high-speed chase through a bunker system beneath Helsinki, and a final showdown on an island in the Finland Archipelago.
