Since 1952, Agatha Christie's murder-mystery play 'Mousetrap' has been playing in London theaters, clocking an estimated 24,000 performances. And each time, at the end of the play, theatergoers are warned not reveal the murderer and thus spoil the ending for prospective audiences. Agatha Christie's family, and fans, would now like to extend that quaint courtesy to potential viewers who may stumble upon the play's Wikipedia page.

The London Independent's Paul Bignell and Matthew Bell speak with Christie's grandson, Matthew Prichard:

My grandmother always got upset if the plots of her books or plays were revealed in reviews – and I don't think this is any different," [Prichard] said. "I think it is a pity if a publication, if I can call it that, potentially spoils the enjoyment for those people who go to see the play. It's not a question of money or anything like that. It's just a pity."

He, and apparently hordes of fans, are petitioning Wikipedia to take down the spoiler from the page--or at least add a "Spoiler Alert" caveat. Wikipedia, according to a spokesperson interviewed by The Independent, isn't budging:

It's exceedingly easy to avoid knowing the identity of the murderer: just don't read it.
