From the publisher's website: "This book tells the incredible story of the cross-correspondence automatic writings, described by one leading scholar of the field, Alan Gauld, 'as undoubtedly the most extensive, the most complex and the most puzzling of all ostensible attempts by deceased persons to manifest purpose, and in so doing to fulfil their overriding purpose of proving their survival'. It is an intensely personal and passionate story on so many levels: May Lyttelton trying to convince her lover Arthur Balfour of her continued existence; Frederic Myers with indomitable persistence trying to produce evidence to prove survival generally; Edmund Gurney and Francis Balfour striving from beyond the grave to influence the birth of children who would work for world peace; Gerald Balfour and his lover Winifred Coombe-Tennant believing that their child, Henry, would be the Messianic leader of this group of children."
