It would seem best to me, in order to avoid controversy and still provide the requested information, to create a "Killer in Agatha Christie's 'The Mousetrap'" article, move the entire plot spoiler there and then reference it in the introduction to the article. In this way, the final wishes of the author are upheld (and a fundamental part of the play's structure) and Wikipedia gets to post everything just as before.--eleuthero (talk) 13:55, 1 September 2010 (UTC)

I disagree. We don't do that for other articles and we shouldn't do it for this one. If you don't want to know the plot, don't read the plot section of the article (or maybe don't read the article at all). --Two Bananas (talk) 14:55, 1 September 2010 (UTC)
This would just be another form of spoiler, and would still be covered by WP:SPOILER. If a section called "Identity of the murderer" isn't enough of a clue to the reader that the identity of the murderer is about to be revealed, an article entitled "Killer in Agatha Christie's 'The Mousetrap'" presumably wouldn't help them much either (and could even be worse, if they got there from a Google search and the one-paragraph article got straight to the point). I'm not sure how hiding the ending behind a link would uphold Christie's final wishes any more closely - the Telegraph article suggests that her grandson considers it a "pity" when any reference work includes the plot in its entirety. --McGeddon (talk) 14:59, 1 September 2010 (UTC)
