|Oh no, you didn't!|
A Scandal in Belgravia is inspired by A Scandal in Bohemia, that famous story where Sherlock Holmes is beaten by Irene Adler. After the episode gets Moriarty out of the way, it launches into an impossible crime, when a man comes to visit Holmes. While his car broke down and he attempted to fix it, he spotted a hiker—and eventually, he spotted the same man dead, murdered somehow but without a single footprint around the body. The police seem to consider this man the prime suspect, but Holmes has a different outlook on things altogether.
