Who is Frankland in the book THE HOUND OF BASKERVILLES and what role does he play?

There is no character named "Frankland" in Sir Arthur Conan Doyle's "The Hound of the Baskervilles." You might be thinking of Selden, a character who plays a relatively minor role in the story.

Here's what you need to know about Selden:

* Occupation: He is a retired army officer living on the moor.

* Personality: He is described as a solitary and eccentric individual, known for his gruff demeanor and tendency to mutter to himself.

* Role: Selden is primarily important because he is the only person other than the protagonists (Holmes and Watson) who sees the Hound.

* Significance: His observation of the hound, coupled with his knowledge of the moor, becomes crucial evidence for Holmes in solving the mystery. He also provides information about the strange happenings on the moor, particularly the unexplained fires.

Perhaps you have confused the name "Frankland" with another character or story. If you can provide any more context or clues, I might be able to offer a more specific answer.
