S5·E10 A Close Run Thing

James and Letty are to be married on board ship by Captain Baines but this nearly does not happen when a group of shanghaied sailors attempt to overwhelm them, the plan being foiled by elderly Captain Jack and the marriage does go ahead. Daniel Fogarty has returned from Australia a rich man. He has begun a charity, the Albert Fund, and is knighted for his services. He marries Elizabeth at last but James's experience has prevented him from being their best man.
