The Keep by F. Paul Wilson

 

(pb; 1981: first book in The Nightworld Cycle, aka the Adversary Cycle)

From the back cover

“The message is received from a Nazi commander stationed in a remote castle high in the Transylvanian alps: ‘Something is murdering my men.’

“Immediately an elite SS extermination squad is sent to destroy whatever enemy dares to challenge the might of the Third Reich.

“And the battle is joined. A battle more awesomely terrifying than anything ever experienced. Between the ultimate evil created by man. . . and the unthinkable, undreamed of, undead horror it has awakened from centuries of darkness to suck the life from living souls again.”

 

Review

Keep is one of my all-time favorite reads. Its setting (World War II-era Romania), with its pulp-meets- classic-story elements, is immediately immersible, Wilson’s penwork deftly balancing horror, story- and character-organic development and turns, action, pacing, and overall writing. It takes familiar tropes and characters and adds intriguing wrinkles to them, making Keep stand out in a wow-that's-great way—worth owning, this, if the above description sounds intriguing to you.

Keep is the first of seven theme- and character-linked books, originally titled The Nightworld Cycle (later, it was supposedly officially renamed the Adversary Cycle). While the first technical sequel, publishing-wise, is The Tomb (1984), Wilson’s official site—according to Wikipedia in February 2025—suggests that the next story-chronological entry is Reborn (1990).

I’ve read that Wilson also has stories linked to the Nightworld/Adversary universe but I’ve yet to check them out.

The studio-butchered film was released stateside on December 16, 1983. Director/screenwriter Michael Mann’s 210-minute version was trimmed to 96 minutes by the studio; because of this, Keep is said to have a jump-around-storyline feel.

The film features these actors: Jürgen Prochnow as Klaus Woermann; Gabriel Byrne as SS Commandant Erich Kaempffer; Ian McKellen as Dr. Theodor Cuza; Alberta Watson as Eva Cuza (in the book her name is Magda Cuza); Michael Carter as Radu Molasar; Scott Glenn as Glaeken; and Robert Prosky as Father Fanescu.
