Sir Charles Baskerville, Baronet was a British gentleman and member of the Baskerville family. He lived at Baskerville Hall in the parish of Grimpen, Dartmoor, England. The sinister circumstances surrounding his death prompted his friend and physician, Dr James Mortimer, to seek Sherlock Holmes' help in protecting his only heir, Sir Henry.
Sir Charles had two younger brothers, Henry's late father and Roger, who passed away in South America. He was married, but was a widower at the time of his death. After he made his fortune, he moved to Baskerville Hall and did a lot of good work and charity for the locals.
