Aaarrgh, a cliffhanger! You are torturing me, woman.
I love the atmosphere in this chapter and all the imagery.
Not to mention some of the descriptions which had me grinning like a loon... 'bellowing martinet' for instance to describe Sherlock. That's one of the most accurate descriptors I've ever read. And learning that the smell of old books makes John 'mildly horny' due to associating it with early make-out sessions... priceless.

Hope the next chapter is up soon; I'm really enjoying this.
