Nestled in the Heidelberg Hills of New York State lies Lake Wankoona. Beneath its tranquil blue surface broods another world, a place inhabited by a race of beings unknown in human history.Impelled by an eerie summons he cannot comprehend, archeologist Hugh Lambert is drawn into the lake's placid depths--and into a vortex of unreality. There, he encounters the unearthly Little Men, who work their scientific necromancy upon the cold corpses of those who had the misfortune to fall into the lake's uncanny bottomlessness. There, also, he meets the coldly beautiful and cruelly enthralling Nalinah, and learns of a sinister scheme to conquer the Upper World--with he, himself, destined to be in the vanguard!Arthur Leo Zagat was famed as "The Horror Story Man," owing to his numerous Weird Menace stories written for Terror Tales and similar magazines of horror. But Zagat also proved capable of writing quality fantasy fiction in the style of A. Merritt, as he proved in the pages of Argosy magazine with memorable novels such as the classic Seven Out of Time and the haunting Drink We Deep.
