What a useful experiment. Listen, let's get Mycroft to send in a couple of his goons, whisk away the Moff and lock him in a secret cell, where he will be forced to write a woman soldier returned from Afghanistan who teems up with a slightly Aspergers woman detective to unravel a conspiracy involving sex boys in Belgravia.

And while we're at it, can I just say that Mycroft is yet another Godlike character. Groan. The smug will kill me.
