The Admiralty has opened an inquiry into the Olympic accident, and Pirrie, Andrews, Morgan and Mark are invited to London. Mark is pleased to see his old friend Kitty, who has become a star. At the inquiry, the First Lord of the Admiralty, Winston Churchill, suggests that the yard could serve several ends in case of military escalation. Joanna Yaeger, Mark's old friend from New York, and Morgan's protégée, is forced into a very dangerous position: a spy. With her unparalleled access she can prove to be extremely useful to the Austro Hungarian and German causes. Back in Belfast, Mark faces a new crisis. Andrea, Sofia's old fiancée, has seen her with him and has told Pietro. Sofia is forced to choose. Sofia stays Mark. Finally he agrees to follow Sofia: they will move to London, together. He will leave Harland & Wolff and all hopes to ever find his own daughter. In a breathtaking ceremony, the Titanic is finally launched.

Titanic's sister ship, the Olympic, is damaged again. Mark can't leave. Sofia also has to postpone her plans. Pietro has been injured at work and she must look after him. Mark and Andrews look for new solutions. The gashes in Olympic suggest that the steel is just too weak. Eventually they have to concede that the steel, combined with the sheer scope, is just not good enough. The double hull would have protected the ship - Perhaps the bulkheads too. For this to become a serious problem, Titanic would have to crash into something very solid. An occurrence that seems remote on the Atlantic Ocean. While Mark and Andrews slowly come to their conclusions, Emily is sentenced to an astoundingly unfair six months in jail. But another terrible event occurs: Conor is shot dead while the Unionists start advocating a new, separate State, Northern Ireland.

The time has come for the great ship to leave for the New World. As Morgan always wanted, Titanic's maiden's voyage will become one of the first great PR events. Sofia and Joanna Yaeger are friends and she gets her a job as an illustrator for the New York Times. Pietro uses most of his money to buy her a ticket. Mark himself only gets on board by chance. The group also includes Jack Lowry, a young riveter we met since the beginning of the story. Violetta with the baby, whom Michael MacCann, has come back to marry. Joanna will be onboard – and so will Kitty, by now an acclaimed actress. A little girl by the name of Sarah, with her mother, will board Third Class. Neither Mark nor his daughter are aware of their presence onboard the Titanic. And, while the ship sails for New York, and Mark and Sofia finally find happiness and reconciliation, we are left asking ourselves: who amongst our characters will survive the great disaster?
