Gimbert is on the warpath with Lovejoy as he his behind on his rent again. We also find out Lovejoy deflowered Gimbert's young sister when she was 15 years old. Something the BBC could get away with in the mid 1980s. It certainly would make Lovejoy something more than a lovable rogue in the post Jimmy Savile, Operation Yewtree era.
Lovejoy while doing some work for Gimbert by looking at a deceased's possession he finds out that the late gentleman who was an engineer was also a skilled art forger, did Victorian caricatures and left some papers with clues. Some American relatives of the dead man turn up claiming to be his relatives.
When two Roman coins are stolen from the local museum, Lovejoy thinks that there were reasons why the forgeries were just nearly perfect. Lovejoy goes to the Isle of Man to talk to the deceased's housekeeper and hears a story of a roman horde which is buried in Manx land even though the Romans never invaded the island.
We get to see more of Lovejoy's daughter who gives some exposition about Romans. We also see Gimbert's sister in this episode. It is quite obvious that the pushy Americans are a villainous pair.
It is an enjoyable episode and once the action moves to the Isle of Man, I got a fair idea where the climax would be set. It is not because I know anything about antiques but I grew up in the island and figured out the obvious clue.
