However, rather than investigate personally, Holmes opts to send his trusted colleague Doctor Watson (André Morell) to take up residence at Baskerville Hall to protect Sir Charles' heir, Sir Henry Baskerville (Christopher Lee) and attempt to get to the bottom of the mystery.But Holmes is not far away and on-hand to unravel the mystery.
