Dr Mortimer, a doctor from Devon visits the detectives in London, he reads them a paper about the legend of the Baskervilles: many family members die all of a sudden because of strange deaths and some nights people see an animal on the moor like the Hound of the Baskervilles. Everyone is frightened, no-one wants to cross the moor at night.
After the death of Sir Charles, Henry Baskerville is the last of the Baskerville. Mortimer and Watson go to London. There they tell the story of the Hound to Henry. They want to go to Baskerville Hall in Devon. Later Holmes goes to Devon too, and he meets Stapleton, a neighbour of Charles.
One day Holmes looks at the picture of Hugo Baskerville, the first Baskerville that died in the moor, and Holmes discovers that Stapleton is a Baskerville and he thinks that… he wants to murder Sir Henry and inherit the Baskerville fortune, and this picture is an important clue: Stapleton bought the huge dog in London and takes it to Devon by train. The huge black creature is a dreadful sight and Sir Charles runs away screaming and falls dead on the path from shock. Then Stapleton takes the hound back to its hiding place on the Grimpen Mire, so Sir Charles’s death is a mystery to all.
The mystery of the Hound of the Baskervilles is solved.
