The sound of pacing footsteps, lights that go on and off and doorbells that ring by themselves even when disconnected, strange rappings, knockings and things that move, ghostly pingpong games and swinging chandeliers are but some of the strange occurrences this family encounters when they move to a new house or so a diary found by workmen. Is it true or the figment of a child's imagination? The finders may never know for the family moved away many years ago leaving the decision of whether the house is haunted or not up to the reader.
