Quebra-cabeça Edgar Allan Poe's Nevermore

Edgar Allan Poe was an American author, poet, editor and literary critic famous for his tales of mystery and the macabre. He is generally considered the inventor of the detective fiction genre and also is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to try to earn a living through writing alone, we all know how that wen. But hey! these geniuses were doing this for the passion of doing it (plus it was a really bad time for writers then) :)
