In Haunted Adelaide, Allen Tiller views ghost stories through a pragmatic lens. Rather than sensationalise the stories, Haunted Adelaide investigates the paranormal through fact-checked, historical information that adds authenticity to some stories, and debunks others. Unlike other paranormal research books, Haunted Adelaide values evidence-based stories over psychic hearsay and gives an unbiased, factual account of the hauntings of the City of Adelaide. Haunted Adelaide is the culmination of 20 years of research on hauntings in the City of Adelaide. It includes research and stories from the world first, Adelaide City Libraries 'Paranormal Historian in Residence' project 'Haunted Buildings in Adelaide', and Allen Tiller's extensive research and investigation into the paranormal in the City of Adelaide.
