ABANDONED. Murder mystery which breaks the fourth wall; Based on 'And Then There Were None' by Agatha Christie, an isolated group of people are murdered, one by one, in gorier and gorier ways, until no one is left

Based on 'And Then There Were None' by Agatha Christie, an isolated group of people are murdered, one by one, in gorier and
gorier ways, until no one is left. Finally, the murderer is revealed: it is the author, of course. I read this book 25-30 years ago, but I would love to read it again.

Where and when is it set?
Did it seem old or new when you read it? (when was it published)

I don't know if this helps, but here's a link to a Goodreads forum about books similar to 'And Then There Were None'.
