Lovejoy is invited to spend the weekend with Charlotte at her best friend's house. The friend is short of money and has a clock she wants valued, but Lovejoy finds a stuffed fish which is worth selling, and misunderstandings arise... Meanwhile, Tinker is keen to thwart Charlie Gimbert's plans to turn Felsham Hall into a health farm, and after studying a twelfth-century charter he starts grazing a flock of sheep around the Hall. Charlie responds by threatening to evict Lovejoy Antiques from the stable yard, so Tinker and Beth take a trip to a health farm.
