When the arrogant aristocratic family of Inkpen Manor decide to develop a memorial garden into a commercial tea shop, the Midsomer Deverell villagers are up in arms. However, when two members of the Inkpen family are then murdered, Troy and Barnaby must weed through the townspeople's sordid lives to uncover the culprit.

When a man's naked body is discovered in the centre of a crop circle in Midsomer Parva, DCI Tom Barnaby laughs off tales of alien abduction. But as more corpses are discovered - each bearing peculiar injuries - it's up to him to uncover who is responsible, or if extra-terrestrial powers are truly at work in Midsomer.
