A long story but only half a mystery
“The Mystery of Marie Rogêt” is a sequel to Edgar Allan Poe’s better-known mystery “The Murders in the Rue Morgue.” Both stories feature the Parisian detective C. Auguste Dupin. Both “Rue Morgue” and “Marie Rogêet” are generally classified as short stories, but the latter—the longest of Poe’s “short” stories—is probably lengthy enough to be called a novella. “The Mystery of Marie Rogêt” was originally serialized in three issues of the magazine Snowden’s Ladies’ Companion in late 1842 and early 1843.
Marie Rogêt is a beautiful young working woman—what the French would call a grisette—who is well-known and well-liked in her neighborhood. One morning she leaves her home, stating that she’s going to visit her aunt nearby. She never arrives at her aunt’s house, however, and instead goes missing. A few days later her body is found floating in the Seine, showing signs of struggle indicating that she was murdered. Poe based this on the real-life murder of a Mary Rogers that happened in New York. There’s nothing wrong with how Poe uses the facts of the Rogers case as the basis for his fiction. He writes, however, as if he expects the reader to know all about Mary Rogers and the details of her case, in the same way that a writer of today might expect everyone in America to know about the Nicole Brown Simpson murder.
This story really makes it obvious that Dupin was an influential precursor to Arthur Conan Doyle’s Sherlock Holmes. Much like Holmes, Dupin is a master of deduction. His cases are narrated by his best friend who is also his roommate, much like Dr. Watson. The two are hanging out in their apartment when they are consulted by a police detective, “G,” who asks for their help—shades of Inspector Lestrade. Then the detective and his friend consult the newspaper accounts of the crime, and they have half the case figured out before they ever even venture out of their sitting room. This is the plot framework of “The Mystery of Marie Rogêt,” and it became the template for the majority of Holmes and Watson stories.
The deductive reasoning that Poe writes for Dupin in this story is impressively ingenious. One wonders how he even thought up some of these details. The way Dupin analyzes the accounts of the case and infers details about the crime would be commendable for a mystery written today; for a mystery written way back at the dawn of the genre, it’s rather stunning. This is a fantastic detective story up until the ending, or rather the lack of an ending. Whereas Holmes and Watson eventually get off the couch and go after the killer, here the reader is robbed of that satisfaction. The resolution of the case happens “off-camera,” so to speak, and the read never really gets to know who the killer is. How utterly disappointing! While Poe may have been a pioneer of the detective fiction genre, he still had some kinks to work out in his narrative approach.
Conan Doyle, of course, added a great deal to the mystery genre. Holmes and Watson certainly have more vivid personalities than Dupin and his unnamed narrator, who could just as well be soulless computers. Based on “Rue Morgue” and “Marie Rogêt,” however, one wonders what a marvelous series of mysteries Poe could have written if he had made a career out of it like Conan Doyle did. Dupin makes a third and final appearance in “The Purloined Letter” (1844).
