S3·E6 The Frighteners

An elderly woman, Jane Thompson who lives in a cottage is receiving threatening phone calls and hears noises in the middle of the night. A landowner, a Mr Walker is keen to get his hands on the her cottage. Nick at first suspects Walker of being behind the threatening behaviour, but Blaketon warns him off. The ladies son-in-law sells the cottage and she eventually is forced to move into a home, but she's not happy and goes back to her cottage. She then refuses to vacate it. Nick arrives and discovers the cottage was not her son-in-law's to sell, making her the rightful owner. It turns out that her son-in-law was responsible for all the threats. Meanwhile Alf finds a kitten and takes it to the station as Mrs. Ventress doesn't like cats. Blaketon orders someone to go and get it put down, but everyone refuses. Blaketon ends up not being so hard and keeps the Kitten as a pet.
