From the acclaimed master of action and suspense. The all time classic.

400 miles north of the Arctic Circle, an airliner crashes in the polar ice-cap. In temperatures 40 degrees below zero, six men and four women survive.

For the members of a remote scientific research station who rescue them, there are some sinister questions to answer – the first one being, who shot the pilot before the crash?

Then, with communications cut and supplies running low, the station doctor must lead the survivors on a desperate bid to reach the coast, knowing all the while that there is a ruthless enemy in their midst, someone working to accomplish their destruction.
