So. Boring. There are only two good things about this short story that are worth mentioning. First of all, because of this story
Mary Rogers, who was brutally murdered in 1841, has been immortalized. Chances are, without Poe's interest in the case of her murder, and his subsequent writing of this story, Mary Rogers would have been a murdered woman lost to history. So there's that.
The second good thing that came out of this short story is
[b:The Beautiful Cigar Girl: Mary Rogers, Edgar Allan Poe, and the Invention of Murder|171112|The Beautiful Cigar Girl Mary Rogers, Edgar Allan Poe, and the Invention of Murder|Daniel Stashower|http://d202m5krfqbpi5.cloudfront.net/books/1309200783s/171112.jpg|1537176]. The Beautiful Cigar Girl does a wonderful job of exploring the murder of Mary Rogers, the life of Edgar Allan Poe, and the processes and events that went into the production of The Mystery of Marie Rogêt. If you like Edgar Allan Poe, then The Beautiful Cigar Girl is a book worth reading. You can probably skip this short story, though.
