The Last of Sheila influenced Knives Out

Rian Johnson has championed The Last of Sheila, written by Stephen Sondheim and Anthony Perkins, as a favourite whodunit and a model for his own. What he took is the puzzle as a game staged by a rich host for guests who all have something to hide, with the audience given every clue the detective has. Glass Onion, the sequel, borrows its island party setup even more directly.
