Mother Dearest by Wensley Clarkson
The bond between a mother and daughter is like no other. But in the case of the Knorr family, with deranged and deluded mother Theresa Knorr at its head, the love and trust that a child naturally places in a parent was grotesquely betrayed under a perverse and terrible set of circumstances. To friends and neighbours, dark-haired Theresa was a devoted, loving mother struggling to bring up five children on her own. Little did they know that, behind closed doors, the same woman was driven by religious extremism, terrible paranoia and an all-consuming jealousy of her daughters' beauty that led to one of the worst cases of serial abuse and murder in history. This is the true story of a family unit twisted out of all recognition by a mother who perpetrated the most evil of crimes. A story that would not have been told was it not for one surviving daughter.
