Book Description
How far would you go to save those you love?
Pluck an ordinary man from the normality of his existence – and throw him into hell....
London chiropractor, David Stichell, a man in the business of freeing others from pain, may seem an unlikely, if intriguing, protagonist. Yet there are dark shadows in his past intent on catching up with him. As murder victims pile up, Stichell finds himself dragged into a remorseless web of treachery and lies, pursued not only by the police, but by very particular powers who want him dead.
