The Devil Aspect

Craig Russell

★★★★☆ Read October 2, 2026

The Devil Aspect has an absurdly good premise, and Craig Russell mostly delivers on it. In 1930s Czechoslovakia, a remote medieval castle has been converted into an asylum housing six of the country's most notorious murderers. A young psychiatrist arrives, determined to dissect their minds and discover what makes them evil, while a Ripper-style killer works the streets of Prague.

The atmosphere is the book's best feature. There's the looming castle, the surrounding forest, the superstitious village nestled below, the damp streets of Prague, and a rich undercurrent of Slavic folklore. It feels as though evil has been accumulating in the landscape for centuries. Each member of the "Devil's Six" carries his own dark history and his own self-justifying mythology, which makes the psychiatrist's interviews with them the most compelling stretches of the book. Russell understands that the most disturbing thing about a killer isn't only what he did, but the story he tells to explain why.

Yet, at times, the psychology feels more suggestive than deep. The Jungian archetypes and regional folklore give the story immense texture, but they ultimately serve a gothic thriller rather than a searching study of human nature. The book also juggles too many moving parts, leaving the middle section overextended, with horrifying backstory stacked on backstory, mythology on mythology, theory on theory. Certain scenes lean into pure pulp, where explicit gore occasionally gets in the way of the ambient dread. Readers sensitive to graphic violence should consider skipping this one.

The resolution is a mixed bag. I saw some of the core twists coming, and by the climax the book's competing ambitions start bumping into each other. I finished it thinking "that was a hell of a story" rather than "what a beautifully constructed novel."

Overall, I enjoyed The Devil Aspect despite its flaws. It's a bit overlong, melodramatic in spots, and not quite as intellectually penetrating as I'd hoped, but it's so atmospheric, inventive, and good at making you want just one more chapter in that castle that I forgave a lot. Recommended if you like murder, madness, folklore, and ancient castles in your gothic horror, and don't mind a predictable stretch or two along the way.
