and this is the Google Banner in honor of the special occasion! Sadly, we can't see it here in the US (I don't know why...does Google think Americans are any less fond of Agatha Christie? Shame on you, Google!) Here's an article if you're interested. So if the grande dame were still around, I think she'd be absolutely thrilled that her birth 120 years ago actually had an incredible impact on the world. A lot of authors come and go, but Christie has been immortalized through her millions of readers, her books and short stories, and by those for whom she was an influence on their own crime-writing careers.
So...happy birthday, Dame Agatha! It may seem silly to be celebrating the birthday of someone who's passed, but she's given me so many hours of absolute enjoyment for many, many years and continues to do so.
