I read it on the train last night! Very entertaining and neat. Although I've never been a subscriber to the whole Schroedinger's Cat thing, as I think that things 'are', independent of whether we perceive them or not.

I rewatched The Reichenbach Fall on Monday and I'm none the wiser about how it all happened. But at the moment I am favouring the theory that virtually the whole episode was an elaborate plan hatched by Sherlock and Mycroft to eliminate Moriarty, and that Sherlock was acting the part throughout. He planned his jump with Molly (and did indeed jump) but into the lorry of rubbish bags. I'm not sure he expected Moriarty to blow his brains out though. His reaction to that was quite strong, but I suppose it could be for the benefit of the watching assassins.

Either that, or there has been a rip in the space-time continuum somewhere....
