Why was Dr. Robert Magnusson murdered? More to the point, why was he murdered five hundred miles from anywhere, in the frozen wilderness of Greenland? And then there is the question of what he was doing seventy miles north of the UCLA base camp, where he should have been - and what were the instruments he had secretly set up and housed in the shack out there? And then again. there is the question of who killed him. When Alex Mason is sent to Greenland to find answers to these questions, what he finds is something far more harrowing and far reaching than anyone could have expected."
