Answer:
Gothic.
Step-by-step explanation:
Modern day thrillers could be said to be an extension or adaptation of the earlier 18th and 19th century form of literature called “gothic”. This latter one employed a combination of horror, a detective-like narrative (like in Poe), death and mystery, and at times even romance, to explore themes of the human psyche and the potential of science. As such, it is easy to see how contemporary thrillers are inspired in that earlier form of fiction.
