Harold Xavier returns to Glenbogle after a 25 year absence. He is a genealogist and has returned to check the records for the Ballantine clan and to deliver a bequest to the rightful heir. Duncan's grandmother may have been part of that family and he's now convinced that he is going to become a laird in his own right. While digging the records out of the attic, Archie finds a case belonging to the family's onetime cook who turns out to have been Katina's mother. Her diary reveals a long hidden secret that suggests Katrina may be part of the family and results in Molly moving out of the house.
