And the silken sad uncertain rustling of each purple curtain
Thrilled me--filled me with fantastic terrors never felt before;
So that now, to still the beating of my heart, I stood repeating
"'Tis some visitor entreating entrance at my chamber door--
Some late visitor entreating entrance at my chamber door;--
     This it is and nothing more."

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.
