This question is about the following stanza from "The Raven:"
Presently my soul grew stronger; hesitating then no longer, "Sir," said I, "or Madam, truly your forgiveness I implore; But the fact is I was napping, and so gently you came rapping, And so faintly you came tapping, tapping at my chamber door, That I scarce was sure I heard you"–here I opened wide the door– Darkness there and nothing more. How does Edgar Allan Poe create suspense in this stanza?
Answer:
The source of the noise is not yet revealed, as no one is standing at the door.
Step-by-step explanation:
The uncertainty about what is going on and who or what is doing the “tapping” behind the narrator's door builds suspense, makes the narrator's soul grow stronger and makes the readers feel anxious and excited about the mysterious situation, and then the narrator goes and opens the door but there is no one!: “Darkness there and nothing more.”
