Is cannibalism the expression of an evil urge for revenge? A form of punishment? A religious rite or a sexual depravity? Or is the taste for the flesh of another human being so irresistible that it is a mixture of all of these, driving one person to kill and devour another. This books delves into the gruesome history of cannibalism and explains the psychology behind anthropophagy – the four medically recognised areas of criminal cannibalism – sexual, aggressive, nutritional and spiritual/religious.
