Things about London BBC Sherlock did not tell you:
1. It smells like fried rubbish. Like a chippy poured their grease into an open container only the container is London.
2. Foxes scream all night long and it sounds like murder. Eventually you stop going to the window to check. I think this is what they want.
3. No place in London is that white. Maybe inner city, but that place also eat souls so you know. makes sense.
