Ghosts I Have Seen (1919) is Violet Tweedale’s memoir of her psychic experiences, some of which involved ghost hunts she conducted. In fact, the very first chapter recounts the investigation she shared with her father of Scotland’s Broughton Hall, alleged to be haunted. Though Tweedale doesn’t mention how old she was, there’s something in her father’s encouraging to her to join him on a prowl around the Hall that suggest she was probably a teenager or close to it. After many disappointing visits to the Hall, a soundless apparition — a woman in white sleepwear — rushed toward and past them. Young Violet was bowled over with fear, but her father managed to chase the ghost a short distance before it vanished before him. More father-daughter ghost hunts were to follow.
