Just throwing this out there but what if ss22 really isnt a cemetery. yeah we have a game that shows a cemetery with Lady Elizabeth Hawthorne's tombstone but if the house of cards may link to that soundstage, perhaps the house of cards IS ss22 and its about the death of Lady Elizabeth Hawthorne... who may be Lady Luck.
This may be irrelevant, someone earlier on this thread posted a search on google about Elizabeth and a book in amazon mentioned that Lady Elizabeth Hawthorne became a widow because her husband was murdered. There are multiple roles in ss22 that are "widow".

"Elizabeth Hawthorne was in love with Marcus Ashford. They were to be married and she thought life couldn't be any better. Little did Elizabeth know her world was about to fall apart. When fate presses her to seek out her fiancé for help late one night, she discovers him with another. Heartbroken she leaves Marcus, jilting him to marry Lord Hawthorne, a man who offered less risk to a tender heart. While she never loved her husband as she did Marcus, she felt it was a safe life, one she could be content with.
Now fate once more compels her to Marcus' sphere. Her husband is killed, leaving her in deep mourning. As she returns to the functions of the world, she receives a strange journal, which had been written by her husband. It's hard to make heads or tails; the writings are in code. Only someone out there can read it and is willing to stop at nothing to get his hands on it. "
I think that is a romance novel, but it is a coincidence.
