Overview: Walter's death has changed the whole picture. Malcontent breeds amongst workers, especially at the shipyard. Larkin has been forced to leave the city. Andrea, to Sofia's embarrassment, is staying at her house. The Chairman, Lord Pirrie, is shocked, and fights with his former friend Henry Carlton – Kitty's father – whom he holds responsible. He seeks an understanding with Michael MacCann, one of the leaders of the workers' movement. They are both intelligent and moral men. Mark keeps his mind on his job and finally identifies the problem with the steel: impurities. But the steel complies with regulations. Eventually Thomas Andrews will see his point, and a new relationship will form. But work is not Mark's only occupation: he finally kisses Sofia. As he goes back to his father, he is assaulted by Bernard Doyle. He accuses him of having left behind his fiancée, Bernard's daughter Siobhan, who died at childbirth.
