When a farmer is kicked to death by his favourite horse, the horse breeder claims it is impossible, while an examination of the farmer´s body provides new clues to the cause of death.
The neighbours confirm that the farmer lived alone, but there had been a mysterious woman, that he met through the personal ads, staying at the house. Searches for the woman turn up nothing until the police discover the farmer´s bank accounts were emptied the day he died.
Kurt and Linda play cat and mouse with the killer when they place their own personal ad. The bait works and Kurt finds himself in deep water.
