Hes being chased by… something.
Its growling; its vision is strange.
Its clearly some sort of animal, but what?

Then, the man narrowly escapes, jumping off an embankment and down to the road below.
As he looks back at what was chasing him though, hes hit by a truck.
His wallet lies in the middle of the road, his I.D.
boasting a familiar name in the Sherlock Holmes canon: Charles Baskerville.
When Sherlock and Joan inform Henry Baskerville of his brothers accidental death, hes suspicious.
That brings Joan to a homeless Iraq vet asking for money on a street corner.
He describes exactly what he saw, even if Joan can hardly believe it.
He says that Eugenes work has been slipping as of late and hes concerned about him.
Eugene insists hes fine though and promptly ends the conversation.
NEXT: Thats how he says patent?
Cornwall turns out to be a dead end though.
Hes a big teddy bear… or dog… and his whereabouts are constantly monitored.
Could someone within the government have wanted Charles dead?
If only things were that simple.
The man behind the research for the War Dogs laughs off all accusations.
Obviously that would anger a lot of inventors, so thats where the detectives turn next.
Sherlock tells him to go outside and put the pool between the two of them.
He seems to have an idea of what theyre dealing with.
When they arrive at Henrys mansion they find the animal in the pool.
Its a robotic dog of sorts, but clearlyverypowerful.
He seems like a real stand-up guy.
Still, it doesnt seem like Stapleton is the killer.
She even has forged documents and everything!
All that work and she doesnt get a cent though.
Instead, shes confronted by Roger and the detectives and her whole plan crumbles.
After delivering its take onThe Hound of theBaskervilles, Hounded once again seesElementaryend on a more dramatic note.
Hes agreed to take some time off for recovery.
Either way, he thanks Sherlock for his help.
Sometimes its nice to see Sherlock saving lives rather than investigating how one was lost.
