Stim, I have to thank you for linking us to that essay.

BUT "impossible for even the best writers to adhere to"?
No way. Difficult, yes; even "almost impossible", perhaps.

If that essay sets up a real impossibility, as you suggest, then there are and will be no detective stories. Or certainly no GOOD detective
stories.

But to write a really proper detective story, applying those rules (as must be done) is damnably difficult.
