Who was Jerry Fisher? What did he say to try and convince Bill to change his mind?

Jerry Fisher was Mr. Bramble’s trainer. They were practising at White Hart, down the road, for the due fight between Bill and the American Murphy at the National Sporting Club. When he came to know that Bill had decided not to fight on Monday, tears came to his eyes. He tried to convince him to come back and practice for the fight. He reminded Mr. Bramble of the money, he reminded him of how the press would react on his decision and most of all he asked him to think of him once before taking any final decision. At last when Bill did not agree to fight, Jerry threatened to disclose the secret of Bill’s profession to Harold. He even told the kid the truth about his father, but to everybody’s surprise, Harold was happy to know that it was his father after all known as “Young Porky” and he was also annoyed that had his father not concealed the truth from him, he would have told all the lads in the school and would have felt proud of it. After the whole drama, when Mr. Bramble was finally convinced that his profession, rather than letting down, is making his son proud. He decided to come back to practice for the 20 round fight.
