Today's Google logo (or Google Doodle, as the company calls its everchanging logo) is one of the most elaborate we've seen: It's a murder scene with one of Google's o's depicting a lady lying dead in the middle of a room full of other characters.
But who's the murderer: the butler, the elegantly attired woman, the gentleman, or the stable boy? There's only one person who can find out: Agatha Christie's fictional detective Hercule Poirot, represented by the capital G in the image, sporting his famous bow tie and mustache.
The logo is, of course, a tribute to the famous crime writer, who was born on September 15, 1890 -- exactly 120 years ago. According to the Guinness Book of World Records, Christie is the world's bestselling author, having sold more than 2 billion copies of her books in 44 languages (puts Stieg Larsson's success on the Kindle in perspective, doesn't it?).
Google often highlights famous writers with its logo; it even had a series of UFO-related doodles celebrating the work of famous science fiction author H.G. Wells.
