I'm starting to note that Sir Arthur Conan Doyle was certainly fascinated by the moors and cliffs of England. They seem to figure prominently in his stories, most prominently of course in The Hound Of The Baskervilles. Silver Blaze based on his story The Adventures Of Silver Blaze also has a setting on the moors.
It's on the moors on one of those English murder mystery nights that the prominent race horse Silver Blaze disappears from the stable of his owner Peter Barkworth. Later on those desolate English moors the trainer Barry Lowe is found dead with a bad head wound.
In this one Jeremy Brett as Sherlock Holmes has to not just deduce clues from humans, but reason why a pair of animals, the selfsame race horse Silver Blaze and a dog behave as they do. As it turns out the current whereabouts of the horse and what happened to its trainer have only the slightest of connections.
This particular Holmes story is a well put together one, the conclusion will perk the interest. And we even learn that Edward Hardwicke as Dr. Watson has a fancy for the sport of kings.
