First of all, the journalist and author Gitta Sereny should be known and valued because of the many books she wrote - not just the two which link to the heinous '60s Mary Flora Bell case: The Case of Mary Bell (1972) and Cries Unheard (1998). Second: do we really lack a thread regarding the crimes of Mary Bell (Wiki) - who was convicted of manslaughter, committed between the ages of ten and eleven, of two small boys (ages four and three) in 1968 - here at WS? Perhaps I'm missing something.

Although much of her work concerned the Third Reich, Ms Sereny became perhaps best known for her investigations into Mary Bell, who served 12 years’ imprisonment for the manslaughter of two young boys in the late 1960s when she was aged between ten and 11.
An acclaimed study by Ms Sereny at the time of the killings was followed in 1998 by a second book, Cries Unheard, which became highly controversial after it emerged that the author had shared her publishing fee with Ms Bell, by then a mother-of-one who had been granted an anonymity order.
In a letter to the mother of one of Bell’s victims, Ms Sereny, who used the book to explain for the first time the child killer’s account of the abuse she herself suffered, said her purpose had been “not to re-live these terrible crimes, but to find some understanding of how they could happen.”
She was a favorite and she will be missed.
