The Hound of the Baskervilles 5 - 8 final

On the moors, Watson encounters strange locals, including the Barrymores, who harbor secrets, and Jack Stapleton, a naturalist with a mysterious sister. As eerie howls echo across the moor and danger mounts, Holmes reveals that Stapleton is actually a Baskerville relative, plotting to kill Sir Henry and claim the family fortune. Stapleton uses a real dog, painted with phosphorus to appear ghostly, to carry out his plan. Holmes and Watson intervene just in time, killing the hound and saving Sir Henry. Stapleton flees into the Grimpen Mire and is presumed dead. The case ends with Holmes once again proving that logic and reason can unravel even the darkest of legends.
