this is terrifying

Whether the Dark Ones were terrifying or psychological crimes were terrifying depended on one's definition and preference of terror. The Dark One was a horror novel with a crime theme. It mainly told the story of a detective who went deep into a criminal organization to expose the dark forces. The characters in the novel, including the psychologist, the killer, the police, etc., their behavior and psychological activities were described in detail, which easily caused the reader's fear and uneasiness. The psychological crime was a horror novel with psychological suspense as the theme. It mainly told the story of a police officer who found a deeper psychological mystery hidden behind the case by investigating a series of suspicious cases. The characters in the novel included the psychologist, detective, criminal, etc. Their psychological state and personality characteristics were all deeply described, which easily aroused the curiosity and desire of the readers. These two novels were excellent horror novels. The readers could choose according to their preferences and horror tolerance.

The combination of creepy visuals and suspenseful storylines usually does the trick. The way the characters and settings are drawn can really send chills down your spine.

Often, it's the reality and the fact that it actually happened that makes a true story terrifying. Knowing that these horrors are not just fictional but part of the real world can be very disturbing.

The Tenants Downstairs was a dark horror novel that told the story of a mysterious and strange rented house. The landlord in the story used spying and slightly changing the life trajectory of others to obtain a completely different ending. The novel was loved by the readers for its fascinating plot and the author's writing skills. Although I don't know of any other horror novels that I would recommend, The Tenants Downstairs might be a good choice.

Well, in some of the stories, the sudden appearance of a ghostly figure can be really terrifying. For example, a character might turn around and see a pale, translucent figure just standing there, with eyes that seem to pierce through their soul.

For some of these novels like 'The Girl with All the Gifts', it's the subversion of traditional zombie concepts. The idea that the zombies are evolving and have more to them than just being a threat makes it terrifying. It challenges our preconceived notions of the genre.

It could be the fact that it was a real event. Knowing that people actually faced this plague, with all its consequences like the spread of disease, the breakdown of communities, and the helplessness in the face of it, makes it terrifying. It might also show the ineffectiveness of initial responses, which added to the horror.

There were two novels with terrifying intelligence that recommended romance. The two novels were The Professor Guessed It Again and Because Twilight Was Hard to Find. " The Professor Guessed It Again " was a modern romance novel. The plot depicted a professor who invited a group of highly intelligent people to his house for a party. They eventually found themselves in a deadly horror game. 'Because Twilight is Hard to Find' was a high-quality mystery romance novel. It told the story of a psychologist and a technical geek, and it involved hackers with high IQ and suspense. I hope these recommendations can satisfy your needs for intellectual horror novels.

I don't think it'll necessarily meet your needs, but I'll try my best to recommend a novel that's most relevant to your description.

His voice was lazy and dangerous."You seem to have a lot of opinions about me." The alarm bells in her heart rang loudly. Danger! He ran over like a lackey, kissed, hugged, and acted coquettishly.
