S5·E4 The Trade Winds

Having exposed Macauley's insurance scam James proposes to Letty, who accepts. Daniel also returns to Liverpool, now a very wealthy man. Robert considers opening a department store and travels with Captain Baines and Samuel to New York, where he is robbed and very nearly press-ganged. James takes on a voyage to import some sheep but it causes him to postpone the wedding and Letty, as a consequence, declares the engagement and wedding off.
