Case 9: Extended Text - The Raven

Once upon a midnight dreary
, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotton lore—
While I nodded, nearly napping, suddenly there came a tapping,

As of some one gently rapping, rapping at my chamber door.

"'Tis some visitor,"
I muttered,
"tapping at my chamber door—

Only this and nothing
more."
