How is Sir Henry Baskerville brave?

Sir Henry Baskerville is the nephew of Sir Charles Baskerville, and heir of the Baskerville estate and fortune. He shows himself to be bold, practical and straightforward, but also impatient, hasty and stubborn. Though not initially superstitious, he later grows anxious over the legend. Sir Henry refuses to take Holmes's advice to stay away from Baskerville Hall until the murderer is behind bars. Sir Henry has physical courage and self-confidence. He is willing to walk the moor at night even as his relatives have been murdered doing just that. He is a very likable person, which makes his murder all the more horrible to contemplate.
