When two five-year-old twins are abducted from a campsite in the Lake District, their grandfather Major Stanley Timms doesn't trust the floundering police investigation in this increasingly complex case, and decides to bring his own Special Forces unit in to investigate. Headed by the unconventional and irrepressible John Tankersley, members of this force are beyond police jurisdiction and have their own rules - but even these may not be enough, as the chilling case seems to implicate both a sophisticated international people-trafficking ring and the family themselves... An intense thriller full of twists and turns.
