The winter drove them mad. It drove every man mad who had ever lived through it; there was only ever the question of degree. The sun disappeared, and you could not leave the tunnels, and everything and everyone you loved was ten thousand miles away. At best, a man suffered from strange lapses in judgment and perception, finding himself at the mirror about to comb his hair with a mechanical pencil, stepping into his undershirt, boiling up a pot of concentrated orange juice for tea. Most men felt a sudden blaze of recovery in their hearts at the first glimpse of a pale hem of sunlight on the horizon in mid-September. But there were stories, apocryphal, perhaps, but far from dubious, of men in past expeditions who sank so deeply into the drift of their own melancholy that they were lost forever. And few among the wives and families of the men who returned from a winter on the Ice would have said what they got back was identical to what they had sent down there.
