How Agatha Christie saved the Latin Mass

Earlier today, my dad and I were talking about Agatha Christie. Well, I was talking and he was looking at the stock market and half listening to me fangirling... But anyway, after a while he asked me if I knew the story of how Agatha Christie saved the Latin Mass. "Uh...NO. TELL ME." was my reply. So he proceeded to tell the following story.

After Vatican II, when the Latin Mass was replaced with the English Mass or Novus Ordo, a group of prominent people came together to sign a petition. Among these people where Catholics, Protestants and even Atheists. All agreed that the Latin Mass had been a huge influence on the Western Culture in terms of art, music, traditions etc... And they all wanted the Latin Mass to be celebrated periodically in England and Wales so that the traditions and rites would not be forgotten. Among these people who signed the petition was Agatha Christie.

The petition was signed and sent of to the Pope. When it was received by the Vatican, it was tossed carelessly on the Pope's desk along with other petitions that were of little consequence. The Pope was reading through the signatures  in silence, when suddenly he exclaimed, "Ah! Agatha Christie!" and signed the petition right then and there. The petition has been nicknamed the "Agatha Christie Indult" ever since.

So apparently the Pope was a fan.
