A mean landowner is reluctant to share an inheritance with his hard-up brother, who is a friend of Jane's. Then Lovejoy intervenes, as a favour to Jane, with a cunning plan which depends on a fake statue.

Vicky finds an old claymore (a Scottish sword) in her attic. Lovejoy buys it at auction and is offered much more than it's worth for it. Puzzled, he investigates and finds the claymore is a map to buried treasure. Someone tries to steal it, so Lovejoy is not the only one hot on the trail. But the treasure is elusive - a supermarket has been built on top of it.

The Lovejoy Antiques team is in Ireland looking for new stock (and also hoping to find a painting by Jack Butler Yeats, for Jane to give her uncle). A bungled robbery leaves them in possession of a page from a rare ancient book, and the search is on for an expert - Brendan Hennessey.

A friend of Charlotte's who runs a nursing home has asked her to sell some things, and Charlotte wants Lovejoy's help with valuations. One patient, Virginia, believes she has a very rare bureau. Then somebody tries to kill Lovejoy. When Charlotte recognizes his resemblance to a dead poet, they begin to suspect who might be behind the attempts on his life. Tinker and Beth are sent off to London in search of the answers.
