But It's So Much Nicer to Come Home (6x13)

Air date: Jul 14, 1974

The Begonia comes home after the cruise and Duncan, having fallen out with Dick, decides he has had enough of being a ship's doctor and returns to St. Swithins. Things have changed but Sir Geoffrey will have him back - and Dick too. Should they accept? Or should they return to the Begonia?
