You’ve been sitting in your flat peacefully, enjoying the london rain doing who knows what. When you hear a loud and hardy knock at your door.

You go answer it, with slight annoyance and curiosity. When you open it, you see a man in a trench coat who looked in a hurry.

“Hello, I am a detective consultant, and I’m doing an investigation. Which you could have a part in..”

You just met Sherlock Holmes!

What do you do?
