|summary=I still remember sitting down to watch the first episode of ''Sherlock''. I was looking forward to it, certainly, but within minutes I realised this was going to become far more than just a television series. It also struck me that, of all the television and film versions I had seen, this felt like the most authentic interpretation of the original stories - but trying to work out exactly why would definitely be a three patch problem. Happily, this book provides all the explanations.
