To Let is the third and final book in the saga (although Galsworthy later published two further trilogies which extend the story). We are now in 1920, about twenty years since Irene married Young Jolyon and gave birth to John and since Soames married Annette, who gave him a daughter, Fleur. The two sides of the family have not met since those times and John and Fleur do not even know of each other's existence.

All the old Forsytes are dead except for Timothy. Val and Holly have returned from South Africa and Val is training racehorses in Sussex. June has opened her gallery near Cork Street.
