The death, quite suddenly, of Sir Charles Baskerville in mysterious circumstances is the trigger for one of the most extraordinary cases ever to challenge the brilliant analytical mind of Sherlock Holmes. As rumours of a legendary hound said to haunt the Baskerville family circulate, Holmes and Watson are asked to ensure the protection of Sir Charles' only heir, Sir Henry - who has travelled all the way from America to reside at Baskerville Hall in Devon.

"You are a wronged woman and shall have justice. Do not bring police. If you do, all will be in vain. Your unknown friend." When a beautiful young woman is sent a letter inviting her to a sinister assignation, she immediately seeks the advice of the consulting detective Sherlock Holmes.

Now it appears the sender of the pearls would like to meet her to right a wrong.
