There is a French story about a nobleman in present-day Bretagne, a horrifically ugly man with a blue beard and enough gold to build and fill a castle. As the story goes, Bluebeard at one point decided that he wanted to marry a young girl, who initially rejected his proposals due to his disgusting features and the fact that all his previous wives had mysteriously disappeared. However, Bluebeard managed to win her over by inviting her and her friends to stay at his estate for eight days, giving them feasts, luncheons, picnics, and taking them fishing. After this, the woman decides that Bluebeard is a respectable man, and decides to marry him despite his blue beard. After they're wed, Bluebeard tells her that he must leave for a few weeks, and he gives her the keys to all the rooms in the house, but forbids her from entering one small closet. After his departure, she invites guests over, and allows them to roam free. While they amuse themselves with Bluebeard's riches, the woman decides that whatever was in that closet could be worth checking out. She opens the door, and is so shocked from what she finds that she drops the key; the bodies of all of Bluebeard's previous wives, hung up and strewn about. She eventually picks up the key and leaves, but finds that there is blood on the key. She tries to clean it off, but it is cursed and will not wipe off. When Bluebeard returns, he finds the key covered in blood and immediately says that she must die for her disobedience. She asks him if she may have a few more minutes to pray, and buys enough time for her brothers to come and slay Bluebeard.

I believe that, while the subject of the story is still Bluebeard, it is instead told from the perspective of one of Bluebeard's earlier wives, who appears much more cynical and less naive than the one in this story. Obviously, however, the earlier Mrs. Bluebeard met a much more... gruesome fate than the newest one.
I believe this is from the perspective of Bluebeard, singing to his final wife after he is killed by her brothers. He feels betrayed by her because she looked in the closet that he forbade her from entering. He cannot see anything wrong with his actions and is appalled that she would betray his trust. It's the passive aggressive musings of a delusional, abusive man.
Ghost's Rebuttal to "Erase"
The first song off the Glean album is clearly sung from the point of view of a person committing murder by strangulation. (It's an ugly word, but I'll say it anyway.) This song is sung from the point of view of a murder victim, and it's only logical to suspect that it's the same person the "Erase" murderer killed. The narrator is basically blaming themselves for what happened, failing to see the warning signs of the culprit, and ultimately resigning themselves to their fate, as though they somehow deserved to die for loving the wrong person.
Caught in the Loop?
There are two clear options here: this song is either a parallel to I’ll Be Haunting You, or it’s part of the memory erase loop of songs. The loop begins with Erase, where the narrator considers erasing his memory after some sort of relationship problem. This branches out to Let Me Tell You About My Operation, where the narrator undergoes the precedure, from the point of view of the surgeon. From there, we stem to Good to Be Alive, when the narrator recovers and Aaa, when the narrator decides to look at old, erased memories. The loop circles back to Erase, when the narrator decides to erase the old memories he saw erased. This will mean in the next loop, the narrator, during Aaa, will try to see himself looking at old memories, erase it, and continue the loop. Mrs. Bluebeard, while it seems obvious this is a murder victim, because of the constant murder references in the song, could potentially be a part of this loop that conjoins Glean and I Like Fun. The I’ll Be Haunting You theory makes sense, as this song has some haunted themes, but the one difference is this is more accepting that you have been murdered by the one you love (if taken literally in this sense) whereas the other is more discovering what people do when you’re not there, for example, when you die. If this is a part of the loop Erase started, (which might also hypothetically include the songs I Like Fun, Music Jail Parts 1 & 2, and Let’s Get This Over With,) the metaphors are subtle, and the timeline is messy, but it’s possible.
