The Casebook of Carnacki the Ghost Finder - William Hope Hodgson

'I saw something terrible rising up through the middle of the 'defence'. It rose with a steady movement. I saw it pale and huge through the whirling funnel of cloud - a monstrous pallid snout rising out of that unknowable abyss. It rose higher and higher. Through a thinning of the cloud I saw one small eye... a pig's eye with a sort of vile understanding shining at the back of it'.
