Simmering hostilities can be found in any family unit and as everyone knows are particularly evident between siblings of the same gender and similar age.
In Susie and Sally's experience their profound animosity towards each other began in early childhood and continued on into adolescence.
The two sisters had always competed for their mother's affection and arguments were frequent, often violent and as the pretty Fraser girls got older, tensions would only increase.
But then suddenly when the youngest girl goes missing and the police are called in, speculation about what may have happened to Sal is inevitable. Sally's disappearance is difficult to understand and hard to contemplate ... but the question is ... did she finally leave home of her own free will after years of rejection ... or is it possible that sibling rivalry might be the reason why she never returned home and perhaps even more crucially ... was her young life cut tragically short up on the West Pennine Moors above the old market town of Chorley? ... The truth can't stay hidden forever ... it never does!
