Cold a Long Time, by John Leake, is the book-length account of the death of Canadian ice-hockey player Duncan MacPherson, and the systematic cover-up of that death. The original idea for the book was to spread awareness of MacPherson's case and increase the chances that a proper investigation would be done. As such, you don't have to read it to find out what Leake and MacPherson's parents deduced, from hard-won evidence, must have happened to him: you can read it on the Cold a Long Time website (warning: the website contains many distressing postmortem photos).
Terrible things happening in cold places can be found almost anywhere, as was demonstrated on a recent flight I took to Boston. The flight itself wasn’t bad at all, though the film selection seemed lacking—until I spotted Tatort Matterhorn in the list.
