Netflix on Tuesday dropped the teaser for the much-anticipated fourth season of its royal drama 'The Crown'. It featured a spine-chilling soundtrack more suited to a dark psychological thriller that offers a deep sense that all is not well with The Windsors.

As the teaser started, the narrator says, "Here is the stuff of which fairy tales are made. A prince and princess on their wedding day. But fairy tales usually end at this point with the simple phrase, 'They lived happily ever after.'"
