In the novella The Case of Charles Dexter Ward, H.P. Lovecraft tells the story of Doctor Marinus Willet’s 1928 exploration of an underground crypt near the city of Providence…

Since the existence of some vast crypt beneath the bungalow seemed virtually beyond dispute, some effort must be made to find it. Willett and Mr. Ward, conscious of the sceptical attitude of the alienists, resolved during their final conference to undertake a joint secret exploration of unparalleled thoroughness; and agreed to meet at the bungalow on the following morning with valises and with certain tools and accessories suited to architectural search and underground exploration.

The explorer trembled, unwilling even to imagine what noxious thing might be lurking in that abyss, but in a moment mustered up the courage to peer over the rough-hewn brink; lying at full length and holding the torch downward at arm’s length to see what might lie below. For a second he could distinguish nothing but the slimy, moss-grown brick walls sinking illimitably into that half-tangible miasma of murk and foulness and anguished frenzy; and then he saw that something dark was leaping clumsily and frantically up and down at the bottom of the narrow shaft, which must have been from twenty to twenty-five feet below the stone floor where he lay. The torch shook in his hand, but he looked again to see what manner of living creature might be immured there in the darkness of that unnatural well….
But Marinus Bicknell Willett was sorry that he looked again; for surgeon and veteran of the dissecting-room though he was, he has not been the same since….He screamed and screamed and screamed in a voice whose falsetto panic no acquaintance of his would ever have recognised; and though he could not rise to his feet he crawled and rolled desperately away from the damp pavement where dozens of Tartarean wells poured forth their exhausted whining and yelping to answer his own insane cries. He tore his hands on the rough, loose stones, and many times bruised his head against the frequent pillars, but still he kept on. Then at last he slowly came to himself in the utter blackness and stench, and stopped his ears against the droning wail into which the burst of yelping had subsided. He was drenched with perspiration and without means of producing a light; stricken and unnerved in the abysmal blackness and horror, and crushed with a memory he never could efface. Beneath him dozens of those things still lived, and from one of those shafts the cover was removed. He knew that what he had seen could never climb up the slippery walls, yet shuddered at the thought that some obscure foot-hold might exist.
What the thing was, he would never tell. It was like some of the carvings on the hellish altar, but it was alive.

Not long after his mother’s departure, Charles Ward began negotiating for the Pawtuxet bungalow. It was a squalid little wooden edifice with a concrete garage, perched high on the sparsely settled bank of the river slightly above Rhodes, but for some odd reason the youth would have nothing else.
