His old servant, Parks--who died early in 1930--had spoken of the strangely aromatic and hideously carven box he had found in the attic, and of the undecipherable parchments and queerly figured silver key which that box had contained: matters of which Carter had also written to others. Carter, he said, had told him that this key had come down from his ancestors, and that it would help him to unlock the gates to his lost boyhood, and to strange dimensions and fantastic realms which he had hitherto visited only in vague, brief and elusive dreams. Then one day Carter took the box and its contents and rode away in his car, never to return. Later on, people found the car at the side of an old, grass-grown road in the hills behind crumbling Arkham--the hills where Carter's forebears had once dwelt, and where the ruined cellar of the great Carter homestead still gaped to the sky. It was in a grove of tall elms near by that another of the Carters had mysteriously vanished in 1781, and not far away was the half-rotted cottage where Goody Fowler, the witch, had brewed her ominous potions still earlier. The region had been settled in 1692 by fugitives from the witchcraft trials in Salem, and even now it bore a name for vaguely ominous things scarcely to be envisaged. Edmund Carter had fled from the shadow of Gallows Hill just in time, and the tales of his sorceries were many. Now, it seemed, his lone descendant had gone somewhere to join him! In the car they found the hideously carved box of fragrant wood, and the parchment which no man could read. The silver key was gone--presumably with Carter. Further than that there was no certain clue. Detectives from Boston said that the fallen timbers of the old Carter place seemed oddly disturbed, and somebody found a handkerchief on the rock-ridged, sinisterly wooded slope behind the ruins near the dreaded cave called the Snake Den. It was then that the country legends about the Snake Den gained a new vitality. Farmers whispered of the blasphemous uses to which old Edmund Carter the wizard had put that horrible grotto, and added later tales about the fondness which Randolph Carter himself had had for it when a boy. In Carter's boyhood the venerable gambrel-roofed homestead was still standing and tenanted by his great-uncle Christopher. He had visited there often, and had talked singularly about the Snake Den. People remembered what he had said about a deep fissure and an unknown inner cave beyond, and speculated on the change he had shown after spending one whole memorable day in the cavern when he was nine. That was in October, too--and ever after that he had seemed to have an uncanny knack at prophesying future events. * * * * *
