Well, I watched it without subtitles and some nuances may have slipped me, but why is Frankland up to Harry after all these years? Is his possible recollection a threat to him, did I get it right?

During John's case notes, he refers to the H.O.U.N.D project as being RUN by Frankland. Now this wasn't quite so, was it?

I noticed that as well! A mistake!

The H.O.U.N.D project was ran by the five people whose names make up the acronym. Frankland was only a young man at the time but always believed in the project and wanted to continue it.

So...I suppose you could say that Frankland was running the H.O.U.N.D project NOW...

This threat has been "dead" for some time so my question might revitalize it:

What is it that they do in Baskerville?
Sherlock asked this question and got no answer. He is curious and so am I.
We see many pipes and valves with hot water steaming out. When Sherlock and John enter Baskerville for the first time there are many sand bags on the ground as if they expect some flooding. And in the background we see a military vehicle with a red cross driving through. Are they preparing for a dangerous experiment and therefore need eventually medical treatment?
When Sherlock and John leave the red cross vehicle can be seen again. Leaving after the experiment is done?
Has Sherlock deduced something about this experiment? Maybe something useful to blackmail Mycroft with to get access into Baskerville again. I negotiated meaning blackmailed?
Was Maycroft even expected to show up in Baskerville to watch the experiment? Sherlocks first question: You were expecting us?

 

I was always wondering why Sherlock used the "bet" subject of all things in order to obtain information from Fletcher who wasn't very keen to talk to him at first.
I only saw this recently:


 
 So Sherlock must have deduced that someone with a horse racing magazine in his trouser pocket apparently would respond to "betting" of any kind.
Of course, it worked - but only because John played along to Sherlock's spontaneous idea so well.

Oh, finally there is something I recognised long before you!
Sherlock took a quite long look at that headline before he started with the bet subject if I remember right.

Then, maybe, you also have an idea why John deduced from Sherlock's appearance (covered in blood, with the harpoon)
"You went on the tube like that?"
I can't see an Oyster card...

Oh, the harpooning-a-pig thing is a reference to the canon story "The Black Peter".
But as for the tube - I have no idea.

Maybe it's the face Sherlock always makes when being forced to use the tube ...

But he's to lazy to walk all the way.

I still don't know most of the canon stories. Shame on me.

Taught in the army.
