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. 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'.
