Notes from a Haunted Isle. In 'Ghoul Britannia', Andrew Martig takes us on a journey through our country and the darkest corners of the sub-conscious. He visits haunted homes, talks to sceptics and believers, attends an exorcism, and asks what meaning lies buried deep within the most famous ghost stories. This rich, absorbing, often very funny, book is a study not just of ghostliness but of Britishness, an exploration of why, now perhaps more than ever, we need the unexplainable - a sense of the unknown.
