What’s the next great locked room mystery?
First, let's investigate what one is ...
While browsing new mysteries, you see this description:
Your first reaction would probably be: “That’s been done so many times!”
And you’d be right. This is a description of one of the classic variations on the “locked-room murder mystery.”
A family is gathered together. Everyone has a motive to kill the old man. He dies suddenly under circumstances that appear to be impossible. All the family members are suspects, but who done it?
(If you saw the 2019 film Knives Out, you saw an exceedingly well-crafted example.)
If the blurb above were written today, it would be doomed unless the story had some very unique twist or amazingly crafted characters and subplots. In this case, the description is from the 1946 novel, Suddenly at His Residence, by Christianna Brand. So, at the time, it wasn’t such an old cliche.
Even in 1946, however, the trope was not original.
In 1935, John Dickson Carr in his classic, The Hollow Man, had his protagonist, Dr. Fell, give a lecture in which he expounded upon the seven types of locked-room mysteries:
The mystery-writing community has been trying to come up with new variations for the locked room mystery trope for nearly a hundred years.
There are anthologies of them, including Locked Room Murders and Other Impossible Crimes: A Comprehensive Bibliography, by Robert Adey (1992). Mr. Adey identified thirteen more “standard” tropes that had evolved over the intervening years.
Does that mean they’ve all been done?
Without reading them all, including the thousands (hundreds of thousands?) written and self-published in the past decade by indie authors, it’s impossible to know.
There are certainly many that have been done to death (sorry!). Certainly, those should be retired from future use (feel free to comment on which are your least favorites).
The question is: what are the great ideas that have not been written yet?
Here are a few crazy ideas:
Have any of these been done already? Comment and let me know.
Can you come up with a variation that can’t be forced into one of the existing 7 (or 20) boxes? Do you have better ideas? Great – let us all know.
Or, write the book, register the copyright, and then tell us about it!
