Renowned journalist and biographer Gitta Sereny covered the Mary Bell case in the 1960s and wrote about it at the time. Mary, then eleven, was charged and subsequently convicted of the manslaughter of two younger boys. Following Mary's release on licence, and in collaboration with her, Sereny provides a thought-provoking biography of someone who was considered to have committed an evil crime of unparalleled horror. She brilliantly delves into the mind of this complex and damaged human being and reveals how little was done to investigate Mary's own troubled circumstances. A powerfully disturbing book, it will resonate with all who read it.
