I am trying to find the name of a movie I saw as a little girl in the mid 1970's. The main character was a little girl who has been befriended by a ghost. The ghost goes about killing off everyone around the little girl: one gets hit with a tree swing gone wild, another falls down the stairs after the ghost ties a string across the top and the person trips, and an older lady, possibly a grandmother, tries to help the girl find the ghost in the attic inside a trunk and then gets hit in the head with the lid of the trunk. I think in the end the girl finds the ghost (you never actually see the ghost at any time, just what it is doing) at his tombstone and the name on it may be 'Paul'. Any help anyone can give me would be greatly appreciated! Thanks!
