Jim Leonard (Lovejoy's antiques mentor) resurfaces, wanting Lovejoy's help with a harmless little scam to catch out a famous dealer. The plot centres on a fake painting by Klimt... Eric plays the role of a rich gentleman farmer, Tinker falls heavily for Jim's wife, and Jane is also drawn into the scheme, but Lovejoy finds out just too late that he too is a victim.

A tough-talking business man hires Lovejoy to recover a sixteenth-century samurai sword which has been stolen from him. Another dealer, Lovejoy's mentor Jim Leonard, buys the sword at an auction, but it is promptly stolen from him by Joanna, the daughter of the original owner. Lovejoy stays on the trail.
