The Price of Fish (S05E13)

Lovejoy receives an invitation to join Charlotte for the weekend at her best friend's home. The friend is in financial trouble and seeks to have a clock appraised, but Lovejoy stumbles upon a valuable stuffed fish that could be sold, leading to a series of mix-ups. Meanwhile, Tinker is determined to stop Charlie Gimbert's plans to convert Felsham Hall into a health retreat. After examining a twelfth-century document, he begins grazing sheep around the Hall. In retaliation, Charlie threatens to kick Lovejoy Antiques out of the stable yard, prompting Tinker and Beth to visit a health retreat.
