On Lammas Night, 1924, Dr Houghton of Aylesbury was hastily summoned by Wilbur Whateley, who had lashed his one remaining horse through the darkness and telephoned from Osborn’s in the village. He found Old Whateley in a very grave state, with a cardiac action and stertorous breathing that told of an end not far off. The shapeless albino daughter and oddly bearded grandson stood by the bedside, whilst from the vacant abyss overhead there came a disquieting suggestion of rhythmical surging or lapping, as of the waves on some level beach. The doctor, though, was chiefly disturbed by the chattering night birds outside, a seemingly limitless legion of whippoorwills that cried their endless message in repetitions timed diabolically to the wheezing gasps of the dying man. It was uncanny and unnatural – too much, thought Dr Houghton, like the whole of the region he had entered so reluctantly in response to the urgent call.

Towards one o’clock Old Whateley gained consciousness, and interrupted his wheezing to choke out a few words to his grandson.

‘More space, Willy, more space soon. Yew grows – an’ that grows faster. It’ll be ready to serve ye soon, boy. Open up the gates to Yog-Sothoth with the long chant that ye’ll find on page 751 of the complete edition, an then put a match to the prison. Fire from airth can’t burn it nohaow.’

He was obviously quite mad. After a pause, during which the flock of whippoorwills outside adjusted their cries to the altered tempo while some indications of the strange hill noises came from afar off, he added another sentence or two.

‘Feed it reg’lar, Willy, an’ mind the quantity; but dun’t let it grow too fast fer the place, fer ef it busts quarters or gits aout afore ye opens to Yog-Sothoth, it’s all over an’ no use. Only them from beyont kin make it multiply an’ work . . . Only them, the old uns as wants to come back . . . ’

But speech gave place to gasps again, and Lavinia screamed at the way the whippoorwills followed the change. It was the same for more than an hour, when the final throaty rattle came. Dr Houghton drew shrunken lids over the glazing grey eyes as the tumult of birds faded imperceptibly to silence. Lavinia sobbed, but Wilbur only chuckled whilst the hill noises rumbled faintly.

‘They didn’t git him,’ he muttered in his heavy bass voice.
