What is a best example of an author including plot elements that contribute to mood suspense?

Example: In Edgar Allan Poe's "The Tell-Tale Heart," the author creates a mood of suspense by:

- Gradually intensifying the narrator's anxiety about the old man's eye.

- Using vivid imagery to describe the old man's appearance and the setting.

- Employing sound effects, such as the beating of the heart, to create a sense of tension.

- Building to a climax in which the narrator finally kills the old man.

All of these elements work together to create a sense of suspense and dread, keeping the reader on the edge of their seat until the very end.
