Edward's calls now grew a trifle more frequent, and his hints occasionally became concrete. What he said was not to be believed, even in centuried and legend-haunted Arkham; but he threw out his dark lore with a sincerity and convincingness which made one fear for his sanity. He talked about terrible meetings in lonely places, of cyclopean ruins in the heart of the Maine woods beneath which vast staircases led down to abysses of nighted secrets, of complex angles that led through invisible walls to other regions of space and time, and of hideous exchanges of personality that permitted explorations in remote and forbidden places, on other worlds, and in different space-time continua.
