What is a good summary of "The Raven"?I know a lot of you have links to long-winded explanations, but I just want to know a brief description of...

It is midnight on a cold December night. A man has been reading
well into the evening and ruminating about the death of his lover, the "lost Lenore," when he
hears a tapping outside. Assuming it is a visitor, he calls out, but there is no answer.
Eventually he discovers that it is merely a bird--a raven. Happy for any company, he begins
talking to the bird and, like some ravens, the bird can speak--but only one word: "Nevermore."
The man begins a long conversation with the bird, and the questions he asks are always answered
simply--"Nevermore." The man, in a state of near madness because of his lost love, begins to
think that the bird has a higher consciousness whose answers have some great philosophical
meaning. He believes the bird has been sent by God to further anguish him. Though he commands the
bird to leave, it remains; the man believes it will stay on its hellish roost within the home
forever as a reminder of the man's unhappiness and "self-torture."
