Okay so thoughts and theories for Sherlock and Co Spoilers for Hound of the Baskervilles:
In no particular order:
- I don't think Henry is making it out alive
-I don't think that was Beryl Stapleton's note he's been kidnapped or murdered or both
-I think Marianne is gone. Either she's faking her illness to go looking for the Spanish girls' murderer or she's been kidnapped. Or it's something to do with the arsenic tunnels
- I BET the house has a secret passage into the tunnels
- I think Rosemary and her husband might have women trapped in the house Or in the Tunnels. Or both (see above)
- And I wonder if the man on the moor is the escaped prisoner. My gut tells me the prisoner stuff is connected to this (that and there's been a ton of foreshadowing to do with the escaped prisoner
- the lights flashing are some way of signalling something. Maybe it's like human trafficking or smuggling. It feels smuggling coded. Though if it's morse code, I imagine John would have caught that, being ex army and all
- Also I think Jack Stapleton is in on it, I dunno what it is, but he's in on it. And his sister, is a prisoner.
