I’m so glad I could provide you a term! But I think you should know it wasn’t my coinage – it comes from the tabloid press of the era, though I got it myself from Murder Must Advertise by Dorothy Sayers.
While it does not per se contain LESS death than Gatsby, MMA it is a significantly more entertaining read, so I strongly recommend it. It was the first Dorothy Sayers novel I ever read, and is a pretty good introduction to Lord Peter, her protagonist, as long as you’re willing to stick it out for a few chapters.
