The "Lord of the Hollow Dark" is set at the same Belgrummo estate first encountered in "Belgrummo's Hell" where an evil cult led by the Aleister Crowley-like character Apollinax have assembled to secure for themselves the "Timeless Moment" of eternal sexual pleasure by sacrificing two innocents, an young woman named Marina and her infant daughter in an ancient warren called the Weem under the Belgrummo Estate. Assisting Apollinax is Archvicar Gerontion, who is really Arcane in disguise. Inspired by the novels of H.P. Lovecraft, Kirk in the "Lord of the Hollow Dark" has Arcane survive a "horrid chthonian pilgrimage" as he faces dark supernatural forces, confront his own family's history of evil, and refuse the appeal of a "seductive, hubristic immorality". The novel concludes with Arcane's own definition of a true "Timeless Moment" which he states: "it comes from faith, from hope, from charity; from having your work in the world; from the happiness of the people you love; or simply as a gift of grace". During his lifetime, Kirk also oversaw the publication of three collections which together encompassed all his short stories. (Three more such collections have been published posthumously, but those only reprint stories found in the earlier volumes.) Many of Kirk's short stories, especially the ghost stories, were set in either Scotland or in the rural parts of his home state of Michigan.
