Culverton will kill Sherlock’s business
So as we have seen from setlock, Culverton Smith has some sort of reality-tv show called ‘Business Killer’.
Sherlock has a business, his business is detective work and consultancy. He figures out Culverton is up to no good and decides to come on this show.
A famous Sherlock Holmes quote is : “My name is Sherlock Holmes, it is my business to know what other people don’t know”. Culverton Smith is a ‘business killer’, therefore he will kill Sherlock’s ability to ‘know what other people don’t know’, AKA he will seek to harm Sherlock’s deducing capabilities as much as he can. I’m not sure how he will do this, perhaps a drug? but in any case, Sherlock won’t be able to just go to his mindpalace and use his deduction powers.
At this time it will be absolutely crucial to have John’s guidance and help in order to defeat this evil man.
