Mystery vs. Horror
There are several similarities and differences between horror stories and mysteries.
Mysteries and Horrors both create suspense, but Horrors draw on the emotional sense of fear to stay exciting and they also tend to include more supernatural occurrences such as monsters. Mysteries on the other hand draw on the infamous sense of curiosity to keep the reader interested and unlike horror stories, they’re often more logical and realistic.
