After her exhausting mission in Amazonia, Kathy Austin is off to Scotland on holiday. She intends to take possession of a house her great-aunt bequeathed her. Unfortunately, she finds the house ruined, burned down a few weeks earlier - and it also appears that the police find the circumstances of the old lady's death a tad ... strange. While the locals blame the ghosts and goblins that haunt the moors, Kathy soon discovers signs that point to a very different explanation: 'crop circles' of ... alien origin?!
