Russian science fiction masters the Strugatsky Brothers (Roadside Picnic, Definitely Maybe) wrote one detective novel. Just that one, but the book is a weird funny ride way more inventive than most mystery novels. It's subtitled One More Last Rite for the Detective Genre, and, among other things, it is in fact a send-up of the classic locked-room, isolated country house murder mystery. Well, it's that, and much more. I took a look at the novel over at Criminal Element.
