Andrew Green, who died in 2004, was for sixty years one of Britain's most active and best-known ghost-hunters. "The Daily Telegraph" famously christened him 'the Spectre Inspector'. The author of best-sellers such as "Our Haunted Kingdom" and "Ghost Hunting, a Practical Guide", he investigated hundreds of reported hauntings during his career, from famous cases such as 'the poltergeist girl of Battersea' to cases where a client had simply taken the wrong medication before bed. His interest in the supernatural began on a summer's day in 1944.As he explored the roof of a haunted house, a compulsion suddenly gripped him - 'Walk over the edge', it urged. Only his father's intervention saved him; he later discovered that several other visitors had not been as fortunate. This experience resulted in a life-long fascination with the paranormal, and the most important cases from his lifetime of research are collected together in this volume - alongside new research and many reports that have never previously been published. This is an essential guide to the career of Britain's most famous ghost-hunter, and indeed to the paranormal history of 'our haunted kingdom'.
