Who is Father Larkin?

Father is the parson/pastor of the only religious institute in the town of Swampsea. He serves as the religious protector of the community, supplying them with Bible Balls in order to ward off the Old Ones in the swamp. During the novel he is a rather sad and awkward individual, showing the pain and suffering he has faced during the deaths of both of his wives, the second from an apparent suicide. He no longer has a real relationship with either of his two daughters, having drawn away from both of them leading to a silence between them that is unbearable. What makes this worse is that he and Briony disagreed publicly on the cause of death for Stepmother, Briony stating in the inquest that suicide could never have been an option for her, more or less accusing Father of murder.
