What kind of a person is Harold?

Do you mean Mr. Harry Kember? He is a handsome but distant man; he is an object of curiosity at Crescent Bay’s. Mr. Harry Kember is not popular with other men who find him too quiet. Yet he does get on well with women, suggesting that he has extramarital affairs. Kember’s marriage is often a topic of gossip, and the women of Crescent Bay believe he will one day murder his wife. Although charming in his own way, Mr. Harry Kember is not trusted in the community. In the last section of “At the Bay” he appears at Beryl’s window and persuades her to leave the bungalow in the middle of the night. It is uncertain what happens next although sinister implications are implied.
