Obviously a good song. Looking retrospectively its slow intro is very refreshing; no singing, short and to the point. The song continues the brutal energy of Wrathchild, however without musically reaching its heights. The fact that there's (essentially) no solo is another plus for me. Early Maiden seemed to be very mature and flexible regarding solos, resulting a high ratio of songs without them.
But no matter the music qualities of the song, what really gets me here are the lyrics:
First, the author. This is based on a story written by one of the world's favorite writers, Edgar Allan Poe. It's said to be one of the first pieces of detective literature.
As far as Maiden is concerned, this is their second plain reference on a piece of literature; establishing a beloved tradition throughout their discography. And it's even better than that: Instead of faithfully following the tale's narrative, Harris cleverly alters it* and we follow a person who is on the run falsely suspected of crimes he didn't commit.
The storytelling within the song is fascinating as the guy cannot speak French to explain his innocence and we left wondering how he even arrived there then. Eloy's Love Over Six Centuries comes to mind; time travel and all, until the final 2 verses will give us a hint that the guy must be a schizophrenic:
I know that it's on my mind That my doctor said I've done it before.
Murders in the Rue Morgue's lyrical innovations make it a great song, ranked somewhere between
52 -68 in Maiden's catalogue, probably ~65.

* Bruce in Flight of Icarus is the prime example of a clever alteration of a known story but Harris did that a full 2 years prior.
