Hi there! I read your comment on my story "Casey Redwood's Written Death". And I'll just explain the answer here on your MB to avoid spoiling the story for future readers. Hope that's okay :)
Well, Casey is a writer. She's too desperate to make a new story when after all, she's still suffering a writer's block. And with that "desperation", she was too driven to what she was writing until she herself has done the crimes (which she wrote on her story) to herself. Nobody thought that the crime wasn't really murder bcoz there were evidences that somebody could've entered her room, like the opened windows and a rope hanging from her room. She really committed suicide. And after her death her book became a best-seller.
That's why in the end, there written, "But no one knew... there were even thousands... or even millions of people who knew how she died. Because Casey Redwood's death was written. But no one would suspect it."
Her death is written in her published book which could have been read by thousands and even millions of people.
I hope I made it clear! :)
If you have any more questions, kindly leave it on my MB, and I'll do my best to answer it.
Thank you so much for reading! ♥
