Monarch of the Glen

A visiting genealogist friend of Hectors discovers a diary which records Katrina's mother, a former servant in the house, as having an affair with someone called ‘H'. Molly is understandably upset by the implications until it is discovered that Katrina's father, the mysterious ‘H' is the genealogist himself.

Archie's wayward sister Lizzie turns up with her New Age boyfriend Gerald and it seems the pair have big plans to turn Glenbogle into a kind of hippy retreat. Archie and Gerald end up at loggerheads, however, when some of their New Age ideals seem to involve Hector rediscovering his lost youth and taking an ill advised swim in the lake.

As the Laird of Glenbogle Archie takes part in a traditional boat race across the loch. He is up against Laird Kilwillie, a neighbouring land-owner. Archie finds himself having to race to win back a MacDonald heirloom ring which has ended up in Kilwillie's possession.

Archie tries to juggle his life in London with his new role as Laird of Glenbogle. He and Lexie make a hectic journey down to London for a special Highland night in his restaurant and he dashes back north just in time to see Katrina beat Kilwillie in the local elections. Understandably Justine's patience is wearing very thin.

Inevitably, Justine gives Archie an ultimatum: come back to London, to the restaurant and her or give up both. Archie offers to sell out of the restaurant to help save Glenbogle, but is that what he really wants. Justine arrives at Glenbogle and Archie must decide where his loyalties and his heart lie, London or Glenbogle. Either way, Justine is determined not to lose her man.
