A short tale, told in diary form, of a scientist working at a polar weather station, who is slowly driven mad by a constant humming noise. The story works well enough in showing how the protagonist loses his grip on reality, as his diary entries become ever more frantic; but I think it falls down towards the end, because the supernatural interpretation that’s offered doesn’t quite convince, making it hard to accept the ambiguity for which Preston seems to be aiming. Almost there, but not quite.
This story appears in Black Static 16. Read all my posts about that issue here.
