Sir Charles Baskerville was the admiration of all because he was a good and generous person.
When Holmes was asked to take the case of the mysterious death of a Baskerville, Dr. Mortimer read from an article of the Devon County Chronicle that Sir Charles Baskerville was admired for his “amiability of character and extreme generosity” (ch 2). After becoming rich in South Africa, Sir Charles moved into Baskerville Hall and began renovating it.
Being himself childless, it was his openly expressed desire that the whole countryside should, within his own lifetime, profit by his good fortune, and many will have personal reasons for bewailing his untimely end. (ch 2)
Charles made generous donations, and was even considered for public office. He was a good man who was loved by his neighbors, and especially by those who lived on the sparsely populated moor. When he died mysteriously, people began to blame the family curse. Holmes was hired to find out what really happened.
It turned out poor Sir Henry was murdered. He had become interested in a certain lady, Laura Lyons, and was paying for her divorce. Stapelton did not approve, and used a huge dog to scare him to death.
