Dear Sherlock,
The posters have all been taken down now by the police. They said it wasn't appropriate for people to be supporting a murderer and giving encouragement to a man who was evil in all aspects. I nearly went out and fought your corner, but I didn't want to get into any more trouble with the police. Nor did I want to undo all your hard work you did to take the focus off me when you 'kidnapped' me and called me your hostage.
The street's less lively without the posters, but their memory remains, and it's nice for me to know that I am not alone in my beliefs.
Everything's going fine here in Baker Street, asides that. Mrs Hudson is enjoying life and is very happy with the increased income she gets from having Nina's rent. Nina and I have been spending a lot more time together, because we do get on very well. I've been looking at her artwork, which is amazing, by the way. It's beautiful to say the least. I can understand now how she manages to pay all her rent by herself; she could sell those paintings for hundreds, even thousands, of pounds.
And what about me? Well, surely you don't need me to tell you that, Sherlock.
I left today's paper, because I found something you might want to look at. There is a potential seriel killer on the loose, and I know how much you love those.
Watch out for cabbies. I know I will.
Your John.
