We lived in a farm cottage just outside Marondellas (now Marondera) in the early 1970s.
It was a one story house which had been built onto on a number of occasions and it had a lovely beamed ceiling in the living room.
We had a Labrador dog - which sat with us every evening.
We had not been in the house very long when we noted that the dog's hair would stand up on end and she would growl while looking at the door to the guest wing of the house.
We could see nothing but she was obviously very agitated by what she saw or heard.
On enquiring of our landlord we discovered that the house had been built for her parents and her father had passed away in the house.
Once we knew who was visiting us we would invite him in when the dog growled and soon even the dog got used to our ghostly visitor
