Have now consulted DS who identifies this as 'water-cooler TV' as all his colleagues have been discussing this too. The consensus seems to be that the power of suggestion was used to convince Watson that the body was Sherlock's. Was the Molly in the path lab in on it? And what about Mycroft? If he had to identify the body he would have to be in on it too!
If Watson "saw what he expected to see" that harks back to last week's Hounds of Baskerville - so maybe a clue? Perhaps the girl provided the drug to that effect? Annobel I agree about the "I am you" clue - sort of ties in doesn't it?
The plot thickens...... and Cumberbatch is assured of work in another series. Nothing actors ike less than being written out, as poor Nigel Pargeter's actor found out!(Somebody Seed??)
Notsogrand Last read Sherlock Holmes when I was about 10 but I think you are right. Conan Doyle was heartily sick of Sherlock and tried to kill him off only to bring him back. Apparently only Moriarty went over the falls. Can't wait to see how they explain his reappearance. It's so brilliantly done, reinterpreting and updating the stories, but keeping the spirit of the originals.
I re-read the original just to check and indeed only Moriarty dies. Sherlock stays hidden because Moriarty's friends are still a danger and he needs to saty "dead" for a bit. It made me realise that on my Kindle the books are listed alphabetically so I had to get out the books to check what happened next!
And a whole year of Ambridge has to be rewritten! I remember that business of Bobby in the shower in "Dallas "(I think) but cannot remember how on earth the writers got themselves out of that! So Will and nauseous Nik would not be married, Pat and Tony would not have had eColi, Kathy's awful kid would still be awful, but Ruth would still be bleating "Deeavid....." Would Henry have been a girl perhaps? I know, I need to get a life.
And Tony Pat, Will and Nic are all a ghastly hallucination brought about by someone putting LSD in the yoghurt, probably awful kid of Kathy, and he is lingering in jail as they have thrown away the key.
In Dallas, didn't someone get taken up in a UFO? But that wouldn't help re the body.......but they could have save his brain/mind and put it in another body. Like Doctor Who. Oh dear this is getting too much for me...but I do miss Nigel.
On the subject of The Archers I think I'll give it up if they have that wretched cow prison built.
Watched the last episode of Sherlock again yesterday in the afternoon when I could be moderately sure of staying awake and I get it all now and how he he did it - wont spoil if for you though!
