Book excerpt: Cannibalism is unquestionably one of the oldest and deepest-seated taboos. Even in an age when almost nothing is sacred, religious, moral and social prohibitions surround the topic. But even as our minds recoil at the mention of actual acts of cannibalism there is some dark fascination with the subject. Appalling crimes of humans eating other humans are blown into major news stories and gory movies: both Hitchcock's 'Psycho' and 'The Texas Chainsaw Massacre' were based on the crimes of Ed Gein, who is profiled, along with others, in this book. In ' Eat Thy Neighbour' the authors put the subject of cannibalism into its social and historical perspective.
