Some old sketches put Lovejoy and Jane on a trail which takes them up to Scotland, where they uncover a plot by another antiques dealer to con one of Jane's friends. At home, Eric is involved with a young woman with some unsavory relations, but she also has an antique mirror to sell. Lovejoy and Jane are moving closer to romance... but who is the girl Lovejoy keeps seeing in the woods?

Lovejoy makes an exhibition of his 'sixth sense' for antiques on a television programme. Later, working on a house clearance, he overlooks an important item and starts to think he may be abusing and losing his talent. After he gets a letter, Lovejoy goes to see another 'divvie' who has lost the magic touch.
