He is a wealthy but kind-hearted, elderly book lover in London. Seeing the face of a friend with a deep and painful past (the man who was Oliver's father) in Oliver, whom he initially judges for supposedly stealing his handkerchief on the street, he takes the boy home, nurses him back to health, and trusts him. Despite the objections of Grimwig and various unfortunate events, he never loses hope, and he uses his own money and energy to sever the ties between Oliver and the criminal gang and to seek justice. He is the man who eventually solves the mystery.
He had good friendships in the past but experienced sorrowful losses (the tragedy of Oliver's father and Agnes). That sorrow, which he could never cast aside, gave birth to the compassion in his eyes.
